The Luxair 100mm 90° round ducting elbow connector
joins two 100mm (4") round ducting pipes at a right angle, allowing your cooker hood ducting run to change direction cleanly and efficiently through a 90° bend. Self-sealing push fit construction means no ducting tape is required at the joint — the connector simply pushes together and forms an airtight seal. Made from solid, rigid, fire-resistant and mould-resistant polymer, it's built for permanent installation behind kitchen walls, ceiling voids, and cabinet runs.
Self-Sealing Push Fit — No Tape, No Mess
Unlike flexible ducting hose connections that rely on tape for an airtight seal, Luxair's rigid round ducting system uses a self-sealing push fit joint — the connector and pipe click together with enough precision to form an airtight connection without tape, sealant, or clips. This makes installation faster, cleaner, and more reliable over the long term.
What This Part Is For — And When You Need It
A 90° elbow is used when your ducting run needs to turn a corner. The most common scenarios are routing ducting from a wall-mounted cooker hood horizontally through an external wall directly behind the hood, changing direction from a vertical run up through a ceiling cavity to a horizontal run across the loft space, or navigating around a joist, structural element, or pipework that sits in the direct ducting path. If your ducting run requires a 45° bend rather than a full 90°, Luxair also stocks 45° elbow connectors in the same 100mm diameter — check the related products below.
Is 100mm the Right Size for Your Hood?
100mm (4") ducting is suitable for cooker hood motors rated below 450 m³/hr. If your hood has a higher-rated motor, you'll need larger ducting for full extraction efficiency — undersized ducting restricts airflow, reduces motor performance, and increases noise. Luxair's recommendation by motor rating:
- Below 450 m³/hr → 100mm (4") ducting
- 450–750 m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2000 m³/hr → 150mm (6") or 200mm (8") ducting
If you're unsure what size your hood requires, check the motor airflow rating on your product label or installation guide, and match it to the guide above. Luxair stocks 90° elbow connectors in 100mm, 125mm, 150mm, and 200mm — all available in the ducting section.
Self-Sealing Push Fit — No Tape Required
Rigid round-to-round connection forms an airtight seal on contact. No ducting tape, sealant, or clips needed at the joint.
90° Right Angle Bend
Connects two 100mm round ducting pipes at a precise 90° angle — ideal for navigating corners, changing direction through walls, or routing around joists and structural elements.
Fire Resistant Polymer Construction
Manufactured from solid, rigid fire-resistant polymer — built for permanent concealed installation behind walls, in ceiling voids, and within kitchen cabinet runs.
Mould Resistant
Resistant to moisture and mould growth — suitable for the warm, steam-heavy environment of a kitchen ducting run.

The Luxair 100mm round rigid ducting pipe
provides a clean, permanent, airtight ventilation run for cooker hoods rated below 450 m³/hr. Each length is 1 metre of solid, rigid fire-resistant and mould-resistant polymer pipe — the core building block of a rigid round ducting installation that connects your cooker hood to an external wall vent or ceiling outlet. Self-sealing push fit ends mean individual lengths connect to each other and to Luxair's full range of 100mm elbows, connectors, and adaptor collars.
Rigid vs Flexible — Why Rigid Ducting Performs Better
Most DIY cooker hood installations use flexible aluminium hose because it's easier to route. Rigid ducting outperforms flexible hose in every measurable way — lower airflow resistance means your motor works less hard to move the same volume of air, less noise because there are no corrugations for airflow to vibrate against, and longer lifespan because rigid polymer doesn't degrade, collapse, or develop leaks over time the way flexible hose can. For any permanent kitchen installation, rigid round ducting is the professional choice.
Self-Sealing Push Fit — No Tape at Any Rigid Joint
Each 1-metre length has push fit ends that connect to Luxair's 100mm elbow connectors, straight connector collars, and adaptor fittings with an airtight seal on contact — no ducting tape, sealant, or clips required at any rigid-to-rigid joint. Ducting tape is only needed when transitioning from rigid pipe to flexible aluminium or plastic flexible hose. For a full rigid run from hood to external wall, no tape is needed at any point.
Build Your Full Ducting Run
A complete 100mm rigid ducting run typically combines several lengths of this 1-metre pipe with the appropriate connectors from Luxair's 100mm range. Common components needed alongside this pipe include 90° elbow connectors for right-angle turns, 45° elbow connectors for gentler direction changes, straight connector collars for joining two pipe lengths end-to-end, round-to-flat adaptors for transitioning to flat rectangular ducting where space is tight, and an external wall vent or grille to terminate the run outside the property. All are available in Luxair's 100mm ducting collection.
All the components you need to complete your 100mm ducting run are available as related products at the bottom of this page — add elbows, connector collars, flat adaptors, flexible hose, and external wall vents to your basket in a single visit without searching for each part separately.
Is 100mm the Right Size for Your Hood?
100mm (4") ducting suits cooker hood motors rated below 450 m³/hr. Using undersized ducting on a higher-rated motor restricts airflow, reduces extraction performance, and increases motor noise. Luxair's size guide by motor rating:
- Below 450 m³/hr → 100mm (4") ducting
- 450–750 m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2000 m³/hr → 150mm (6") or 200mm (8") ducting
Luxair stocks 1-metre rigid round ducting pipe in all four standard sizes — 100mm, 125mm, 150mm, and 200mm — all available in the ducting section.

The Luxair 100mm round ducting connector collar
...is a straight inline joiner that connects two lengths of 100mm round rigid ducting pipe end-to-end, extending your ducting run in a straight line without any change in direction. Also known as a straight connector, inline coupler, or ducting joiner, it's the most frequently needed component in any rigid round ducting installation — used wherever a 1-metre pipe length ends and the run needs to continue straight.
When You Need This Part
You need a connector collar every time one length of 100mm round ducting pipe ends and you need to continue the run in the same direction. In practice that means any ducting run longer than one metre will require at least one connector collar, and longer runs through ceiling voids, wall cavities, or above kitchen cabinets will typically need several. It is also used to repair a ducting run where a section of pipe has been cut, damaged, or needs to be extended — push the collar over both cut ends and the joint is sealed without tape or adhesive.
Self-Sealing Push Fit — Airtight Without Tape
The connector collar slides over the ends of two 100mm rigid pipes and forms an airtight push fit seal on contact. No ducting tape, sealant, or fixings are needed at a rigid-to-rigid connection. The only time ducting tape is required in a Luxair rigid ducting run is when connecting to flexible aluminium or plastic flexible hose — all rigid-to-rigid joints throughout the run are fully self-sealing.
Part of Luxair's Complete 100mm Ducting System
This connector collar is designed to work seamlessly with every other component in Luxair's 100mm round ducting range — 1-metre rigid pipes, 90° elbow connectors, 45° elbow connectors, round-to-flat adaptors, flexible aluminium hose, and external wall vents and grilles.
All the other components you need to complete your 100mm ducting run are available as related products at the bottom of this page — add everything to your basket in a single visit without having to search for each part separately.
Is 100mm the Right Size for Your Hood?
100mm (4") ducting is correct for cooker hood motors rated below 450 m³/hr. For higher-rated motors, use larger ducting to avoid restricting airflow and increasing motor noise:

The Luxair 100mm round to flat rectangular horizontal ducting adaptor
...converts a 100mm (4") round ducting outlet to a 220mm x 90mm flat rectangular duct, running horizontally — the transition piece used when your cooker hood has a round outlet but your ducting run needs to travel along the top of kitchen wall cabinets in a flat profile. Self-sealing push fit on both the round and flat ends, and the slim 220mm x 90mm flat profile fits neatly into the space between the top of a standard wall cabinet and the ceiling.
Why You Need a Round to Flat Adaptor
Most cooker hoods — wall-mounted, canopy, and telescopic models — have a round outlet, typically 100mm, 120mm, 125mm, or 150mm in diameter. But in many kitchens, the most practical route for the ducting run is along the top of the wall cabinets, across the ceiling void, or through a narrow space where round pipe simply won't fit cleanly. Flat rectangular ducting sits flush against the cabinet top, takes up far less visual space, and routes cleanly through tight gaps that round pipe can't navigate. This adaptor is the transition piece that makes that change possible — from round outlet to flat run — in a single fitting.
Horizontal Orientation — What That Means for Installation
This connector is specifically designed for a horizontal transition — where the flat duct exits the adaptor running parallel to the ceiling or cabinet top, travelling left or right away from the hood. If your ducting needs to transition from round to flat in a vertical direction — travelling upward through a cabinet or ceiling void — Luxair also stocks the 100mm round to flat vertical 90° elbow, which makes the same transition but with the flat duct exiting upward. Check which orientation your installation requires before ordering.
Dimensions — Round and Flat Ends
Round inlet: 100mm (4") diameter — fits directly onto 100mm round rigid ducting pipe or 100mm hood outlet collars. Flat outlet: 220mm x 90mm — the UK standard flat rectangular duct size used across Luxair's full flat ducting range. Both ends are push fit and self-sealing against their matching pipes and fittings. No ducting tape required at rigid-to-rigid connections.
Part of Luxair's Complete 100mm Ducting System
This adaptor connects seamlessly to Luxair's full range of 100mm round components on one side and the 220mm x 90mm flat ducting range on the other — including flat duct lengths, flat 90° horizontal elbows, flat 90° vertical elbows, flat inline connector collars, and flat ducting clips.

Is 100mm the Right Size for Your Hood?
100mm (4") ducting is correct for cooker hood motors rated below 450 m³/hr. For higher-rated motors, use larger ducting to maintain full extraction efficiency:
- Below 450 m³/hr → 100mm (4") ducting
- 450–750 m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2000 m³/hr → 150mm (6") or 200mm (8") ducting
Luxair stocks round to flat adaptors in multiple sizes — all available in the ducting section.

📊 Why This Page Has High Conversion Potential
Buyers searching "100mm round to flat ducting adaptor cooker hood" or "how to connect round duct to flat duct kitchen" are at a very specific point in installation — they have the hood in, they have the flat duct, and they're missing the one piece that joins them. The horizontal vs vertical distinction in the description is genuinely useful content that no competitor page explains clearly, and it directly prevents a wrong purchase — which reduces returns, builds trust, and keeps buyers on your site rather than returning the part and going elsewhere.
The Luxair 100mm round to flat 150mm x 70mm vertical 90° ducting elbow
...transitions a 100mm (4") round ducting outlet upward into a 150mm x 70mm flat rectangular duct at a right angle — the fitting used when your cooker hood has a round outlet and the ducting run needs to exit vertically upward into a cabinet void, ceiling cavity, or wall chase before continuing as flat rectangular duct. Self-sealing push fit on both the round and flat ends.
Vertical vs Horizontal — Which Elbow Do You Need?
This is the question that causes the most wrong purchases in the ducting range, so it's worth being precise. This fitting makes the transition from round to flat with the flat duct exiting upward — used when the ducting run needs to go straight up from the hood outlet into a wall cabinet or ceiling void before running horizontally. If your ducting run needs to transition from round to flat and then travel horizontally along the top of cabinets immediately — without first going upward — you need the 100mm Round to Flat Horizontal Connector instead, which has the flat duct exiting sideways rather than upward. Check which direction your duct exits the adaptor before ordering — the flat duct exit direction is fixed on each fitting.
150mm x 70mm — The Slim Flat Duct Profile
This fitting connects to 150mm x 70mm flat rectangular ducting — the slimmer of the two flat duct sizes in Luxair's range. At 70mm deep, this profile fits into very tight spaces above cabinets, inside wall chases, and in ceiling voids where the larger 220mm x 90mm flat duct profile won't fit. If your installation has restricted vertical space above the cabinets or within the wall void, the 150mm x 70mm system is the right choice. All flat duct lengths, elbows, connectors, and clips in the 150mm x 70mm size are available in Luxair's 100mm ducting collection — make sure every component in your run matches this size, as the two flat duct sizes are not interchangeable.
When This Fitting Is Used in a Typical Installation
The most common installation scenario for this elbow is a canopy or built-in hood recessed inside a kitchen cabinet, where the round outlet exits upward through the top of the cabinet carcass into the void above. The round-to-flat vertical elbow sits at the top of the cabinet, transitions the round outlet into a flat profile, and the flat duct then runs horizontally through the void toward an external wall vent. It's a neat, low-profile solution that keeps all ducting hidden within the cabinet and ceiling structure with no visible pipework anywhere in the kitchen.
Part of Luxair's Complete 100mm Ducting System
This elbow works seamlessly within Luxair's full 100mm ducting range — connecting to 100mm round pipe on one side and the 150mm x 70mm flat system on the other.

Is 100mm the Right Size for Your Hood?
100mm (4") ducting is correct for cooker hood motors rated below 450 m³/hr. For higher-rated motors use larger ducting throughout the entire run:
- Below 450 m³/hr → 100mm (4") ducting
- 450–750 m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2000 m³/hr → 150mm (6") or 200mm (8") ducting
Round to Flat Transition Elbow — Vertical 90° Converts 100mm round duct to 150mm x 70mm flat rectangular duct, with the flat duct exiting upward at 90°. For installations where duct runs upward before transitioning to flat.
Self-Sealing Push Fit on Both Ends Airtight connection at round and flat ends without ducting tape. Tape only needed when connecting to flexible hose.
Round Inlet: 100mm (4") Diameter Fits directly onto 100mm round rigid ducting pipe and standard 100mm hood outlet collars.
Flat Outlet: 150mm x 70mm Slim flat duct profile — fits tight cabinet voids and wall chases. Not interchangeable with the 220mm x 90mm flat duct system.

⚠️ One Dimension to Double Check
Your page title says 150mm x 70mm flat outlet but your product images appear to show a larger fitting that could be the 220mm x 90mm size — the image filenames reference both sizes. Before publishing, physically measure the flat outlet on the actual product and confirm it's 150mm x 70mm, not 220mm x 90mm. If the flat outlet is actually 220mm x 90mm, this and the horizontal connector are the same flat duct size and the distinction in the description above still applies — just update the dimensions throughout to match what the product actually measures.
The Luxair 100mm x 60mm flat rectangular ducting pipe
...is a 1-metre length of rigid, low-profile flat duct — the core building block of a flat ducting run for cooker hoods where a round pipe profile won't fit or where a slim, concealed installation above kitchen cabinets or within a wall chase is required. At just 60mm deep, the 100mm x 60mm profile is the slimmest flat duct in Luxair's range, fitting into tight spaces where the larger 220mm x 90mm flat duct profile would be too bulky. Self-sealing push fit ends connect to all Luxair 100mm x 60mm fittings.
Why Choose Flat Ducting Over Round?
Round ducting is fine for direct runs through walls, but in kitchens where the duct needs to travel along the top of wall cabinets, through a narrow void between ceiling and cabinet, or along the inside of a wall chase, flat rectangular ducting is the practical choice. The 100mm x 60mm profile sits flush against a flat surface, takes up minimal vertical space, and routes cleanly through gaps that round pipe simply can't navigate. It's also far less visible if it happens to be partially exposed — a flat rectangular profile blends into ceiling lines and cabinet tops far more discreetly than round pipe.
The Slimmest Flat Profile in the Range — Only 60mm Deep
At 60mm deep, this is Luxair's slimmest flat ducting option — narrower than the standard 220mm x 90mm flat duct used in most UK kitchen installations. It's specifically suited to installations where the void above the wall cabinets is tight, where a wall chase has limited depth, or where the duct needs to route through a space that won't accommodate a deeper profile. If your installation has more clearance available and your hood has a higher motor rating, the 220mm x 90mm flat channel provides greater airflow capacity and is recommended for hoods rated above 300 m³/hr.
Self-Sealing Push Fit — No Tape at Rigid Joints
Each 1-metre length has push fit ends that connect directly to all Luxair 100mm x 60mm flat fittings — elbows, connector collars, clips, and adaptor pieces — with an airtight seal on contact. No sealant or fixings are needed at any rigid-to-rigid joint throughout the run.
Build Your Complete 100mm x 60mm Flat Ducting Run
A complete flat ducting installation using this pipe typically combines several 1-metre lengths with fittings from Luxair's 100mm x 60mm range — 90° horizontal elbows for left or right turns along the cabinet top, 90° vertical elbows for direction changes into ceiling voids, inline connector collars for joining pipe lengths end-to-end, ducting clips for securing the run to ceiling joists or cabinet tops, and a round-to-flat adaptor to transition from the hood's round outlet into this flat profile.

Is 100mm x 60mm the Right Size for Your Hood?
The 100mm x 60mm flat duct is an equivalent airflow cross-section to 100mm round ducting and is suitable for cooker hood motors rated below 450 m³/hr. For higher-rated motors use larger ducting to maintain full extraction efficiency and avoid restricting airflow:
- Below 450 m³/hr → 100mm round or 100mm x 60mm flat ducting
- 450–750 m³/hr → 125mm or 150mm round, or 220mm x 90mm flat channel
- 750–2000 m³/hr → 150mm or 200mm round ducting

The Luxair 100mm x 60mm flat ducting 90° horizontal elbow connector
...joins two lengths of 100mm x 60mm flat rectangular ducting at a right angle in the horizontal plane — turning the duct run left or right along the top of wall cabinets, across a ceiling void, or within a wall chase without changing the vertical height of the run. Self-sealing push fit, and the smooth interior bore maintains airflow efficiency through the bend.
Horizontal vs Vertical — Which Elbow Do You Need?
This is the question that causes the most wrong purchases in the flat ducting range. A horizontal elbow turns the duct run left or right — the duct stays at the same height throughout the bend, travelling along a flat surface like a cabinet top or ceiling line. A vertical elbow turns the duct run upward or downward — used when the run needs to change floor level, drop into a cabinet void, or rise up through a ceiling. If your ducting run travels along the top of your kitchen wall cabinets and needs to turn a corner at the end — left or right — this is the correct fitting. If your run needs to go up or down at any point, use the 100mm x 60mm 90° Vertical Elbow instead.
Where This Fitting Is Used in a Typical Installation
The most common scenario for this elbow is a flat ducting run travelling horizontally along the top of kitchen wall cabinets that needs to turn a corner — for example, when the hood is on one wall but the external vent is on an adjacent wall. The flat duct runs straight from the adaptor at the hood outlet along the cabinet top, hits this horizontal elbow at the corner, turns 90°, and continues along the next run of cabinets toward the external wall vent. Two horizontal elbows back-to-back can also be used to create a U-shaped offset where structural elements or pipework block a straight run.
Self-Sealing Push Fit — No Tape at Rigid Joints
Both ends of this elbow are push fit and self-sealing against 100mm x 60mm flat ducting pipe and matching fittings — no ducting tape, sealant, or clips required at any rigid-to-rigid joint in the run. Tape is only needed when the run transitions to flexible aluminium or plastic flexible hose at any point. The smooth interior bore through the bend minimizes airflow turbulence compared to sharper or poorly fitted junctions, maintaining extraction efficiency through the corner.
Part of Luxair's Complete 100mm x 60mm Flat Ducting System
This elbow connects seamlessly with every other component in Luxair's 100mm x 60mm flat ducting range — 1-metre flat duct pipes, vertical 90° elbows, inline connector collars, ducting clips, and round-to-flat transition adaptors.

⚠️ Image Check Required
One of your three product images has a filename referencing 220mm x 90mm — the larger flat duct size. Before publishing, confirm all three images show the 100mm x 60mm fitting and replace any that show the wrong product. Mismatched product images are one of the most common causes of returns on ducting parts and will hurt your seller ratings if left uncorrected.
The Luxair 100mm x 60mm flat ducting 90° vertical elbow connector
...joins two lengths of 100mm x 60mm flat rectangular ducting at a right angle in the vertical plane — turning the duct run upward or downward at 90° where it needs to change height, drop into a cabinet void, rise through a ceiling, or transition between different levels within a wall or ceiling structure. Self-sealing push fit.
Vertical vs Horizontal — Choosing the Right Elbow
This is the most important distinction in the flat ducting range and the most common source of wrong purchases. A vertical elbow changes the height of the duct run — it turns the duct upward or downward. A horizontal elbow keeps the duct at the same height and turns it left or right. If your ducting run travels along the top of kitchen cabinets and needs to drop down into a cabinet void at the end, or rise up through a ceiling at the end of the run, this vertical elbow is the correct fitting. If the run needs to turn a corner left or right at the same height — along the cabinet top or ceiling line — use the 100mm x 60mm 90° Horizontal Elbow instead. Getting this right before ordering saves a return trip.
Where This Fitting Is Used in a Typical Installation
The vertical elbow appears most commonly in two places in a kitchen ducting run. First, at the start of the run — where a flat duct coming horizontally out of a round-to-flat adaptor needs to turn downward to route inside a wall cavity or upward to exit through the ceiling above the cabinets. Second, at the end of the run — where a flat duct travelling along the top of cabinets needs to turn downward to exit through the wall at a lower height, or upward to enter a ceiling void before connecting to an external wall vent. In both cases the vertical elbow makes the direction change cleanly in a single rigid fitting.
Self-Sealing Push Fit — No Tape at Rigid Joints
Both ends are push fit and self-sealing against 100mm x 60mm flat ducting pipe and matching fittings — no sealant, or fixings needed at any rigid-to-rigid connection. The smooth interior bore through the bend minimises turbulence, maintaining extraction efficiency through the direction change.
Part of Luxair's Complete 100mm x 60mm Flat Ducting System
This vertical elbow works seamlessly with every other component in Luxair's 100mm x 60mm flat ducting range — 1-metre flat duct pipes, 90° horizontal elbows, inline connector collars, ducting clips, and round-to-flat transition adaptors.

1. Meta description — currently says "45 degree" and "220mm x 90mm" — both completely wrong. Replace with the new meta description above immediately.
2. Product images — two image filenames reference 150mm x 70mm. Confirm all images show 100mm x 60mm fittings and replace any that don't.

The Luxair 100mm x 60mm flat duct inline connector collar
...is a straight joiner that connects two lengths of 100mm x 60mm flat rectangular ducting pipe end-to-end, extending the run in the same direction without any change in height or angle. Also known as a straight connector, inline coupler, or duct joiner, it's needed in any 100mm x 60mm flat ducting installation where the run exceeds one metre — and in longer runs through cabinet tops, ceiling voids, and wall chases, you'll typically need several. Self-sealing push fit construction.
When You Need This Part
Every time one length of 100mm x 60mm flat duct ends and the run continues straight, you need a connector collar. In practice that means any installation requiring more than one metre of flat duct will need at least one, and runs of three or four metres will need two or three. It's also the correct part for repairing an existing flat ducting run — if a section has been cut, cracked, or damaged, slide the collar over both ends and the joint is sealed without tools, adhesive, or tape. Always order one or two more than you think you need before starting installation — running short mid-job means a wasted trip.
Self-Sealing Push Fit
The connector collar slides over the ends of two 100mm x 60mm flat duct lengths and forms an airtight push fit seal on contact. No sealant, or fixings are needed at any rigid-to-rigid joint, all rigid push fit joints throughout the run are fully self-sealing.
Part of Luxair's Complete 100mm x 60mm Flat Ducting System
This connector collar works seamlessly with every other component in Luxair's 100mm x 60mm flat ducting range 1-metre flat duct pipes, 90° horizontal elbows, 90° vertical elbows, ducting clips, and round-to-flat transition adaptors.

The Luxair 100mm x 60mm flat ducting clips
...secure flat rectangular ducting pipe to ceiling joists, cabinet tops, wall surfaces, and timber framing throughout your cooker hood ducting run. Sold in a pack of 2, they prevent flat duct from sagging, shifting, or pulling apart at joints over time — particularly important in longer runs through ceiling voids and above wall cabinets where the duct is unsupported over distance. Designed specifically for 100mm x 60mm flat rectangular ducting and compatible with all Luxair 100mm x 60mm flat duct pipe.
Why Ducting Clips Matter — And Why Most Installers Forget Them
Flat ducting clips are the most commonly forgotten component in a kitchen ducting installation. The duct goes up, the elbows connect, everything looks secure — and then six months later the run has sagged at the midpoint, a joint has partially separated, and extraction performance has dropped noticeably. Clips prevent all of this. Fitted every 600–900mm along a horizontal run and at every change of direction, they anchor the duct securely to the structure above, eliminate sag, keep joints tight, and ensure the ducting run performs at full efficiency for the lifetime of the installation. Order them with your duct — they cost less than £5 and save a much more expensive remediation later.
How Many Do You Need?
As a general guide, fit one clip approximately every 600–900mm along any horizontal flat duct run, plus one clip on each side of every elbow connector. For a 3-metre run with two elbows that means a minimum of 5–6 clips — so two packs of 2 as a minimum, three packs to be safe. Always order slightly more than your calculation suggests — running one clip short at the end of an installation means leaving the last section unsecured, which is exactly where sagging and joint separation starts.
Compatible With 100mm x 60mm Flat Ducting Only
These clips are sized specifically for 100mm x 60mm flat rectangular duct pipe. They will not fit 220mm x 90mm flat channel ducting, 150mm x 70mm flat duct, or any round ducting profile. Luxair stocks ducting clips in all flat duct sizes — make sure you select the clip that matches your duct size exactly.

The Luxair 125mm to 100mm ducting reducer collar
The Luxair 125mm to 100mm ducting reducer collar connects a 125mm (5") round ducting outlet to a 100mm (4") round ducting run — the transition fitting used when your cooker hood has a 125mm outlet spigot but your existing ducting run, wall duct sleeve, or external wall vent is sized for 100mm. The collar is push fit on both ends, and ducting tape is recommended around both joints to ensure a fully airtight seal — particularly important on a reducer fitting where any air leakage at the size transition will reduce extraction performance and allow cooking odours to escape into the void behind your cabinets.
When You Need a Reducer — And When You Don't
A reducer is needed in one specific situation — when the outlet size on your hood doesn't match the size of your ducting run. The most common scenario is a new cooker hood with a 125mm outlet being connected to an existing 100mm duct sleeve in the wall — common in older UK properties where 100mm ducting was installed as standard and a newer, higher-rated hood is being fitted. Rather than replacing the entire ducting run, a single reducer collar solves the mismatch at the connection point. However, it's important to understand the trade-off — reducing from 125mm to 100mm will restrict airflow compared to running 125mm throughout. For hoods rated above 450 m³/hr, Luxair recommends running the correct 125mm, 150mm, or larger ducting throughout rather than reducing, to maintain full extraction efficiency.
The Right Way to Use This Reducer
Fit the reducer at the hood outlet only — connecting the 125mm spigot on the hood to the start of a 100mm run. Do not use a reducer mid-run to reduce pipe size after a straight section of larger ducting, as this concentrates the airflow restriction at a single point and significantly increases motor noise. The reducer is a practical solution for connecting to an existing 100mm wall sleeve — it is not a substitute for correctly sized ducting throughout a new installation.
125mm to 100mm — Check Your Hood's Outlet Size First
Before ordering, confirm the outlet diameter on your specific hood. The outlet spigot is usually found on the top of the hood body and is clearly marked in the installation manual. Common UK outlet sizes are 100mm, 120mm, 125mm, 150mm, and 200mm — and they are not interchangeable. If your hood has a 120mm outlet rather than 125mm, this reducer will not fit — check Luxair's full reducer range for the correct size.
All the other components for your ducting run are available as related products at the bottom of this page — add everything to your basket in one visit.
Ducting Size Guide by Motor Rating
Using this reducer means your effective ducting size is 100mm throughout. Confirm your hood's motor rating is suitable for 100mm ducting before using this fitting:
- Below 450 m³/hr → 100mm ducting is correct
- 450–750 m³/hr → 125mm or 150mm ducting recommended
- 750–2000 m³/hr → 150mm or 200mm ducting recommended
If your hood is rated above 450 m³/hr, consider whether upgrading the wall sleeve to 125mm or larger is a better long-term solution than reducing.
125mm to 100mm Round Ducting Reducer
Connects a 125mm (5") round ducting outlet to a 100mm (4") round ducting run. Solves size mismatches between hood outlet and existing ducting.
Push Fit on Both Ends — Ducting Tape Recommended
Push fit connection on both the 125mm and 100mm ends. Ducting tape is recommended around both joints to ensure a fully airtight seal at the size transition.
Tapered Internal Profile
Smooth tapered bore minimizes airflow turbulence through the size reduction.
Use at Hood Outlet Only
Fit at the connection between hood and duct run only — not mid-run. Mid-run reduction significantly increases motor noise.
Check Hood Outlet Size Before Ordering
Confirm your hood has a 125mm outlet spigot. Not compatible with 120mm, 100mm, 150mm, or 200mm outlets.
Suitable For Hoods Rated Below 450 m³/hr
Reducing to 100mm restricts airflow. For hoods rated above 450 m³/hr, correctly sized ducting throughout is recommended instead.
Fire Resistant Polymer Construction
Solid rigid fire-resistant polymer — safe for permanent installation.

The Luxair 100mm aluminium flexible ducting hose
...is a 1.5-metre length of corrugated aluminium flexible duct — used for the final connection between a cooker hood outlet and a rigid ducting run, or for short sections where rigid pipe cannot be routed due to tight bends, awkward angles, or restricted access. Flexible enough to navigate spaces that rigid pipe cannot reach and compressible for easy routing, it's the practical solution for the last section of any installation where a direct rigid connection isn't possible. Ducting tape is recommended at both ends to create a fully airtight seal at every connection point.
Where Flexible Hose Is Used — And Where It Isn't
Flexible aluminium hose is a connection tool, not a full ducting solution. It's used in three specific situations — as a final connection between the hood outlet and the start of a rigid ducting run where the hood needs a small amount of movement tolerance, as a short bridge section over a gap of up to 1.5 metres where rigid pipe cannot be fitted due to a structural obstruction, and as a transition piece between a rigid run and an external wall vent where the last section needs to flex into position. For the main body of any ducting run — the sections running along cabinet tops, through ceiling voids, or within wall chases — rigid ducting always outperforms flexible hose in extraction efficiency, noise, and long-term reliability. Use flexible hose where you need flexibility, rigid ducting everywhere else.
Always Use Ducting Tape at Every Joint
Unlike Luxair's rigid push fit ducting which forms an airtight seal without tape, flexible hose connections require ducting tape at both ends to achieve an airtight joint. Without tape, the corrugated hose end will not seal fully against the spigot or rigid pipe it connects to, allowing cooking air, odours, and moisture to leak into the void behind your cabinets. Wrap ducting tape firmly around the full circumference of both connection points — the end connecting to the hood outlet and the end connecting to the rigid pipe or wall vent. Don't stretch the tape as you wrap — lay it flat and overlap each pass by at least half the tape width for a reliable seal.
Keep Flexible Hose Runs as Short as Possible
Every metre of flexible aluminium hose adds measurably more airflow resistance than the same length of rigid pipe — because the corrugated internal profile creates turbulence that smooth-bore rigid pipe doesn't. As a practical guide, keep any flexible hose section to 1.5 metres or less, avoid compressing it tightly around bends (a gentle curve always outperforms a sharp kink), and never fold or crush the hose at any point — a kinked section can reduce airflow by 30–40% and significantly increase motor noise. If your connection requires more than 1.5 metres of flexible hose, use rigid ducting for the main run and reserve the flexible hose for the final 0.5–1 metre connection only.
Is 100mm the Right Size for Your Hood?
100mm (4") flexible hose matches 100mm round ducting and is suitable for cooker hood motors rated below 450 m³/hr. For higher-rated motors use the correct larger size throughout — mixing sizes with a reducer at the flexible hose connection is not recommended as it compounds the airflow restriction:
- Below 450 m³/hr → 100mm flexible hose
- 450–750 m³/hr → 125mm or 150mm flexible hose
- 750–2000 m³/hr → 150mm or 200mm flexible hose

100mm Aluminium Flexible Ducting Hose — 1.5 Metres
Corrugated aluminium flexible duct for final connections, short bridge sections, and tight-access runs where rigid pipe cannot be fitted.
Ducting Tape Required at Both Ends
Unlike rigid push fit ducting, flexible hose connections are not self-sealing. Ducting tape must be applied at both the hood outlet and the rigid pipe or vent connection for an airtight joint.
1.5 Metre Length
Sufficient for most final connection requirements. Keep flexible sections as short as possible — under 1.5 metres — to minimise airflow resistance and motor noise.
Aluminium Construction
Corrugated aluminium profile — flexible, lightweight, and heat resistant for use in kitchen ventilation environments.
Use for Final Connections Only
Rigid ducting is recommended for all main runs. Use flexible hose only for the final connection or short bridge sections where rigid pipe cannot be routed.
Avoid Kinking or Compressing Tightly
Sharp bends or crushed sections reduce airflow by 30–40% and increase motor noise significantly. Always use gentle curves with the minimum bend radius maintained.
Suitable For Hoods Rated Below 450 m³/hr
Matches 100mm round ducting. For higher-rated motors use 125mm, 150mm, or 200mm flexible hose throughout.

Louvred External Wall Vent with Backdraft Shutter
Luxair louvred external wall vents combine a durable polystyrol construction with a built in backdraft shutter system — preventing cooking odours, cold draughts, and insects from entering the property through the wall duct when the extractor is not in use. Available in four colours and three size options to suit any exterior finish and any standard ducting diameter up to 150mm.
Red Dot Design Award Winners
These vents are Red Dot Design Award winners — recognised for combining aesthetic appeal with practical ventilation performance. The louvred face design provides effective airflow when the extractor is running while maintaining a clean, considered appearance on the external wall.
Colours and Sizes
- White (RAL 9010) — 100mm, 125mm, 150mm
- Brick Red Terracotta (RAL 8004) — 125mm, 150mm
- Light Grey (RAL 7042) — 125mm, 150mm
- Anthracite Grey (RAL 7016) — 125mm, 150mm
Select your colour and size from the options above. Check the product title to confirm the exact size and colour before purchasing.
Material and Durability
Constructed from robust synthetic thermoplastic polystyrol — polystyrol does not decay, rot, or degrade over time when exposed to humidity or atmospheric dampness. The backdraft shutter is built into the vent body and operates mechanically — opening under airflow pressure from the extractor and closing when the extractor is off, blocking reverse airflow without any power or maintenance requirement.
Pair With the Luxair Heat Retention Cartridge
For maximum energy efficiency — particularly in airtight or modern fabric first homes — pair these louvred vents with the Luxair heat retention valve. The combination eliminates backdrafts entirely and significantly reduces heat loss through the wall duct when the extractor is not running. Click here to view these.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
The Luxair premium square steel wall vent
...is a handmade steel ventilation grille designed for the external or internal termination of a cooker hood ducting run — available in stainless steel, matt black, white, and anthracite to match your kitchen exterior, internal wall finish, or existing fixtures. Unlike mass-produced plastic louvre vents, this is a hand-finished steel grille built to last the lifetime of your kitchen installation, with an integrated fly screen and a weighted backdraught shutter that closes automatically when the extractor is off. Available with an optional 100mm or 125mm connector collar to complete the connection in a single order.
External or Internal — Two Uses, One Grille
This vent works equally well as an external wall vent — terminating the ducting run on the outside face of an exterior wall, allowing extracted cooking air to exit the building — or as an internal wall grille — used where ducting passes through a partition wall into another void or space and a clean, finished face is needed on the internal side. The square steel profile sits flush against brick, render, timber cladding, and internal plaster equally well, making it the right choice for both applications in a single product.
Integrated Fly Screen — Keeps Insects Out
Every Luxair square steel wall vent includes a built-in fly screen behind the grille face — essential for external installations where insects, wasps, and spiders would otherwise enter the ducting run when the extractor is off. The fine mesh screen is integrated into the vent body rather than clipped on separately, so it stays in place permanently without the risk of falling out or being accidentally removed during cleaning.
Four Finishes — Matched to Your Kitchen or Exterior
Stainless steel suits kitchens with stainless appliances and modern exteriors — and resists corrosion and weathering indefinitely on external walls. Matt black coordinates with dark kitchen schemes, black window frames, and contemporary exterior finishes where a standard white vent would stand out. White is the most popular choice for painted rendered exteriors, white PVC window surrounds, and internal walls with white plasterwork. Anthracite is the go-to for grey rendered exteriors, aluminium window frames, and kitchens with dark grey or slate colour schemes — the fastest-growing finish choice in new-build and renovation projects.
Optional Connector Collar — Complete the Job in One Order
Add a 100mm or 125mm connector collar to connect the duct pipe inside the wall directly to the back of the vent grille — the fitting that completes the connection between your ducting run and the vent face. 6" options will fit straight onto 150mm rigid pipe or semi rigid ducting. Ducting tape is recommended around the collar joint to ensure a fully airtight seal at the wall termination point. If you already have the correct collar, select "Not Required". All other components for your ducting run are available as related products at the bottom of this page — add everything in one visit.

Round vs Square Which Wall Vent Do You Need?
Both the round and square Luxair steel vents perform identically and share the same features — the choice is purely about aesthetics and compatibility with your wall and ducting run. The round vent is the natural choice when your ducting run uses round pipe throughout, as the circular profile aligns directly with the round duct and requires no transition at the wall face. It also suits period properties, brick-built homes, and any exterior where a circular vent reads as more traditional or sympathetic to the building's architecture. The square vent suits contemporary rendered exteriors, new builds, and modern kitchens where clean geometric lines are preferred. Both are available in the same four colours choose based on your building and personal preference.
External or Internal One Grille, Both Uses
The round steel vent works equally well as an external wall vent terminating the ducting run on the outside face of an exterior wall, or as an internal wall grille where ducting passes through a partition wall and a finished face is needed on the internal side. The steel construction handles outdoor exposure without rusting, warping, or discolouring — unlike plastic louvre vents that become brittle and discoloured within a few years of UV and weather exposure.
Integrated Fly Screen Insect Protection Built In
Every Luxair round steel wall vent includes a built-in fly screen permanently integrated behind the grille face — preventing insects, wasps, and spiders from entering the ducting run when the extractor is off. The screen is fixed into the vent body rather than being a clip-on component, so it won't fall out, get lost, or be inadvertently removed during cleaning.
Four Finishes Matched to Your Exterior or Interior
Stainless steel is the most weather-resistant option and suits modern kitchens and contemporary exterior finishes — corrosion-proof and low maintenance indefinitely. Matt black coordinates with dark exterior joinery, black window frames, and bold kitchen schemes where a standard white vent would stand out. White is the most versatile choice for rendered exteriors, painted brickwork, white PVC surrounds, and white-walled interiors. Anthracite suits grey render, aluminium framing, and the darker exterior palettes increasingly popular in new build and renovation projects across the UK.
Optional Connector Collar Complete the Job in One Order
Add a 100mm or 125mm connector collar to connect the duct pipe inside the wall directly to the back of the vent grille — the fitting that completes the connection between your ducting run and the vent face. 6" options will fit straight onto 150mm rigid pipe or semi rigid ducting. Ducting tape is recommended around the collar joint to ensure a fully airtight seal at the wall termination point. If you already have the correct collar, select "Not Required".

150mm × 70mm Flat Ducting Pipe — 1 Metre
This is the standard 1 metre straight section of 150mm × 70mm flat rectangular ducting pipe, suitable for cooker hood installations with motor speeds up to 750m³/hr. It is part of the Luxair 5" push-fit airtight ducting system.
Why Flat Rigid Ducting Outperforms Flexible Aluminium Pipe
Rigid flat ducting is significantly more efficient than flexible aluminium pipe. Flexible aluminium tube has a corrugated interior surface that creates turbulence and resistance in the airflow, reducing extraction performance — particularly over longer duct runs. The smooth interior walls of rigid flat ducting allow air to travel freely with minimal resistance, delivering consistently higher extraction rates from the same motor. Luxair recommends rigid flat ducting for all ceiling extractor hoods and all extractors with a minimum motor speed of 350m³/hr.
The 5" Push-Fit System
This pipe is part of the Luxair 125mm (5") push-fit airtight ducting range. The system combines 150mm × 70mm flat rectangular ducting and 125mm round ducting — both formats carry equivalent airflow rates and are fully interchangeable within the system.

150mm × 70mm Flexible Ducting Hose — Extends to 500mm
This flexible hose connects two 150mm × 70mm flat rectangular ducting sections and extends up to 500mm, bending at virtually any angle to route the duct run around obstacles or through tight spaces. It is part of the Luxair 5" push-fit airtight ducting system.
Where This Component Is Used
Unlike rigid bends which are fixed at 90°, this flexible hose adapts to any angle — making it the correct solution wherever a precise bend angle isn't known in advance or where rigid components can't be fitted. It is particularly suited to ceiling cooker hood installations where the duct must navigate between ceiling joists, up and over structural obstacles, or through irregular ceiling voids where a fixed-angle elbow would be impractical.
When to Use Flexible Hose vs Rigid Bends
Rigid 90° elbows and bends should be used wherever the installation allows — they offer lower airflow resistance than flexible hose. Use this flexible hose where the installation requires it: tight joist spaces, irregular angles, or where rigid components physically cannot be fitted. Keep the flexible section as short and straight as possible to minimise resistance in the duct run.

This connector joins two 150mm × 70mm flat rectangular ducting sections together on a straight duct run, extending the run beyond a single pipe length. It is part of the Luxair 5" push-fit airtight ducting system.
Important — Use Pipe Clips Either Side of Each Joint
On longer duct runs of one metre or more, pipe clips must be fitted either side of each connector joint to prevent the ducting from sagging under its own weight. Sagging joints can break the airtight seal and reduce extraction performance. See the 150mm × 70mm flat ducting pipe clips in the Luxair ducting range.

125mm Round Ducting Pipe — 1 Metre
This is the standard 1 metre straight section of 125mm round rigid ducting pipe, suitable for cooker hood installations with motor speeds up to 750m³/hr. It is part of the Luxair 5" push-fit airtight ducting system.
Why Rigid Round Ducting Outperforms Flexible Aluminium Pipe
Rigid round ducting is significantly more efficient than flexible aluminium pipe. Flexible aluminium tube has a corrugated interior surface that creates turbulence and resistance in the airflow, reducing extraction performance — particularly over longer duct runs. The smooth interior walls of rigid round ducting allow air to travel freely with minimal resistance, delivering consistently higher extraction rates from the same motor. For any installation where rigid ducting can be fitted, it is always the preferred choice over flexible aluminium pipe.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting

125mm Round Ducting Straight Connector
This connector joins two 125mm round rigid ducting sections together on a straight duct run, extending the run beyond a single pipe length. It is part of the Luxair 5" push-fit airtight ducting system.
Why Round Rigid Ducting Outperforms Flexible and Rectangular Alternatives
Round rigid ducting delivers superior airflow performance compared to both flexible aluminium tube and rectangular ducting of a comparable size. The circular cross-section and smooth interior walls minimise turbulence and resistance, allowing the motor to extract at its rated capacity across the full length of the duct run. Luxair recommends rigid round ducting for all ceiling extractor hoods and all extractors with a minimum motor speed of 350m³/hr.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:

125mm Round to 150mm × 70mm Flat Ducting Connector
This adapter connects a 125mm round ducting pipe (or 125mm flexible aluminium tube) to a 150mm × 70mm flat rectangular ducting pipe on a straight run. Unlike the 90° bend version, this connector makes the transition between round and flat formats in a straight line and can be used in either a vertical or horizontal position. It is part of the Luxair 5" push-fit airtight ducting system.
Where This Component Is Used
Use this connector wherever your duct run needs to transition between round and flat ducting formats without changing direction — for example, where the round outlet of a cooker hood or ceiling extractor connects to a flat rectangular duct run along a wall or ceiling, or where a flat section terminates into a round pipe to connect to a fan or wall outlet. The connector works equally in vertical and horizontal orientations.

125mm Round Ducting — 90° Elbow Bend
This elbow connects two 125mm round rigid ducting sections at a right angle, routing the duct run smoothly through a 90° corner without restricting airflow. It is part of the Luxair 5" push-fit airtight ducting system.
Where This Component Is Used
This elbow is particularly suited to two common installation scenarios. For wall-mounted cooker hoods ducted directly through an outside wall, the elbow connects the round outlet of the hood to the duct section passing through the wall — turning the run from vertical to horizontal in a single component. For island cooker hood installations, the elbow routes the duct from the hood body up into the ceiling void, turning the run at the ceiling level to continue horizontally above. It can also be used in any installation where a 90° direction change is required in a round duct run.

Aluminium Ducting Joint Tape — 50mm × 45m Roll
This is a silver-faced aluminium foil sealing tape for securing and sealing ducting joints, adapters, and ventilation connections. Supplied on a white paper liner, the tape is self-adhesive and applies directly to ducting surfaces to prevent air escaping at joints — maintaining full extraction power throughout the duct run.
Where This Tape Is Used
Use this tape to seal any ducting joint where an airtight connection is required — including joints between rigid pipe sections, around adapters and connectors, at wall outlets, and for repairs to existing ventilation ducting. Any air escaping at a joint directly reduces extraction performance at the hood, and sealing all joints is recommended for maximum efficiency regardless of the ducting system used.

150mm to 125mm Ducting Reducer Collar — 6" to 5"
This reducer collar steps down the ducting diameter from 150mm (6") to 125mm (5"), connecting a 150mm round spigot or duct outlet to a 125mm round ducting run. It is most commonly used to connect the motor housing spigot of a cooker hood or extractor fan directly to a 125mm round duct pipe where the motor outlet is 150mm but the duct run is 125mm. It is part of the Luxair 6" airtight ducting system.
Where This Component Is Used
Use this reducer wherever the ducting needs to step down from 150mm to 125mm — typically at the motor outlet where the hood's 150mm spigot connects to an existing or preferred 125mm duct run, or where a 6" duct section terminates into a 5" run. Always check your motor outlet diameter and intended duct size before ordering to confirm this is the correct reducer direction for your installation.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
✓ 150mm to 125mm ducting reducer collar — steps down from 6" to 5" round ducting diameter
✓ Connects 150mm motor housing spigot to 125mm round duct run — most common use at the cooker hood or extractor fan outlet
✓ Check motor outlet diameter before ordering — this reducer steps down from 150mm to 125mm; confirm direction before purchasing

The Luxair 125mm to 100mm ducting reducer collar
The Luxair 125mm to 100mm ducting reducer collar connects a 125mm (5") round ducting outlet to a 100mm (4") round ducting run — the transition fitting used when your cooker hood has a 125mm outlet spigot but your existing ducting run, wall duct sleeve, or external wall vent is sized for 100mm. The collar is push fit on both ends, and ducting tape is recommended around both joints to ensure a fully airtight seal — particularly important on a reducer fitting where any air leakage at the size transition will reduce extraction performance and allow cooking odours to escape into the void behind your cabinets.
When You Need a Reducer — And When You Don't
A reducer is needed in one specific situation — when the outlet size on your hood doesn't match the size of your ducting run. The most common scenario is a new cooker hood with a 125mm outlet being connected to an existing 100mm duct sleeve in the wall — common in older UK properties where 100mm ducting was installed as standard and a newer, higher-rated hood is being fitted. Rather than replacing the entire ducting run, a single reducer collar solves the mismatch at the connection point. However, it's important to understand the trade-off — reducing from 125mm to 100mm will restrict airflow compared to running 125mm throughout. For hoods rated above 450 m³/hr, Luxair recommends running the correct 125mm, 150mm, or larger ducting throughout rather than reducing, to maintain full extraction efficiency.
The Right Way to Use This Reducer
Fit the reducer at the hood outlet only — connecting the 125mm spigot on the hood to the start of a 100mm run. Do not use a reducer mid-run to reduce pipe size after a straight section of larger ducting, as this concentrates the airflow restriction at a single point and significantly increases motor noise. The reducer is a practical solution for connecting to an existing 100mm wall sleeve — it is not a substitute for correctly sized ducting throughout a new installation.
125mm to 100mm — Check Your Hood's Outlet Size First
Before ordering, confirm the outlet diameter on your specific hood. The outlet spigot is usually found on the top of the hood body and is clearly marked in the installation manual. Common UK outlet sizes are 100mm, 120mm, 125mm, 150mm, and 200mm — and they are not interchangeable. If your hood has a 120mm outlet rather than 125mm, this reducer will not fit — check Luxair's full reducer range for the correct size.
All the other components for your ducting run are available as related products at the bottom of this page — add everything to your basket in one visit.
Ducting Size Guide by Motor Rating
Using this reducer means your effective ducting size is 100mm throughout. Confirm your hood's motor rating is suitable for 100mm ducting before using this fitting:
- Below 450 m³/hr → 100mm ducting is correct
- 450–750 m³/hr → 125mm or 150mm ducting recommended
- 750–2000 m³/hr → 150mm or 200mm ducting recommended
If your hood is rated above 450 m³/hr, consider whether upgrading the wall sleeve to 125mm or larger is a better long-term solution than reducing.
125mm to 100mm Round Ducting Reducer
Connects a 125mm (5") round ducting outlet to a 100mm (4") round ducting run. Solves size mismatches between hood outlet and existing ducting.
Push Fit on Both Ends — Ducting Tape Recommended
Push fit connection on both the 125mm and 100mm ends. Ducting tape is recommended around both joints to ensure a fully airtight seal at the size transition.
Tapered Internal Profile
Smooth tapered bore minimizes airflow turbulence through the size reduction.
Use at Hood Outlet Only
Fit at the connection between hood and duct run only — not mid-run. Mid-run reduction significantly increases motor noise.
Check Hood Outlet Size Before Ordering
Confirm your hood has a 125mm outlet spigot. Not compatible with 120mm, 100mm, 150mm, or 200mm outlets.
Suitable For Hoods Rated Below 450 m³/hr
Reducing to 100mm restricts airflow. For hoods rated above 450 m³/hr, correctly sized ducting throughout is recommended instead.

Luxair Thermobox® Heat Retention Cartridge — 125mm and 150mm
The Thermobox® is a multi-award-winning heat retention cartridge that fits within a 125mm (5") or 150mm (6") ducting vent or round ducting tube. It is a purely mechanical back-pressure shutter solution — no power required, no wiring, and it can be retrofitted to any existing ducting installation.
The Problem It Solves
Every ducted cooker hood extraction system has one weak point: the wall vent or duct outlet through the external wall. When the hood is not in use, this opening allows cold air to enter the building, warm air to escape, and on windy days produces the characteristic noisy flapping sound of standard vent flaps. In draughty or exposed properties this heat loss is continuous and significant — a permanent gap in the building's thermal envelope directly behind the kitchen.
How the Thermobox® Works
The Thermobox® ShutterTec retention system uses three flaps arranged in sequence, sealed by magnets. When closed, the three flaps create two sealed air chambers within the cartridge body. Air is a poor heat conductor — trapping it in sealed chambers creates an insulating barrier that performs up to 20 times better than a standard wall vent. When the extractor is running, air pressure from the motor opens the flaps automatically. When the hood is switched off, the magnets pull the flaps closed, sealing the chambers and restoring the insulating barrier. No power, no sensors, no maintenance.
Key Benefits
For properties in exposed or windy locations, the Thermobox® also eliminates the noise of flapping vent covers and prevents cold air being pushed back into the kitchen by wind pressure — a common problem with single-flap wall vents that standard back-draught shutters cannot fully address.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
✓ Luxair Thermobox® multi-award-winning heat retention cartridge — insulates up to 20× better than a standard wall vent

Aluminium Inline Ducting Silencer — 125mm and 150mm, Up to 22dB Noise Reduction
This inline ducting silencer significantly reduces the operational noise of a cooker hood extraction system by up to 22dB, depending on frequency. It fits directly into any 125mm (5") or 150mm (6") round ducting run and requires no modification to the existing installation — simply insert inline between two duct sections. Available in lengths from 460mm to 585mm — check the product title for the exact length before ordering.
How It Works
The silencer body is constructed from thick-walled aluminium tube for high stability and durability. Inside, a 25mm glass wool insert at 16kg per m³ density absorbs sound energy as extraction airflow passes through — attenuating noise across a broad frequency range by up to 22dB. The glass wool material is non-combustible, certified to DIN 4102, making it suitable for use in kitchen extraction systems where heat resistance is a requirement.
Where This Component Is Used
This silencer is fitted inline on any round ducting run — positioned between the cooker hood outlet and the wall vent to reduce the noise transmitted through the duct. It is particularly effective for ceiling cooker hood installations using round ducting, where the duct run passes through ceiling voids and the motor noise can resonate through the structure. For installations using flat rectangular ducting, use a round-to-flat converter collar to connect the flat duct sections either side of the silencer.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting

125mm Semi-Rigid Aluminium Flexible Hose — 3 Metres
This is a 3 metre length of 125mm semi-rigid aluminium flexible ducting hose. Unlike fully flexible corrugated tube, this semi-rigid hose can be bent into shape by hand and holds the position it is formed into — making it suitable for duct runs that require a firm, fixed-shape flexible section rather than a loose, unsupported hose.
Important — Not Part of the Push-Fit Airtight System
This hose is not part of the Luxair self-seal push-fit ducting range. To connect this hose to 125mm rigid ducting pipe, a 125mm collar connector is required (available separately in the Luxair ducting range). Ducting tape should also be used at all joints to ensure an airtight seal — unlike push-fit components, this hose does not self-seal at connections.
Specification
- Diameter: 125mm (inner bore)
- Length: 3 metres (compressible for transportation)
- Construction: Single-layer aluminium with 4mm corrugation depth
- Flexibility: Semi-rigid — hand-bendable and shape-retaining
When to Use Semi-Rigid vs Rigid Ducting
Semi-rigid flexible hose is the correct choice where rigid pipe sections cannot be installed due to restricted access, irregular angles, or tight spaces — but where a fully flexible corrugated tube would be too unsupported or loose for the installation. The semi-rigid construction holds the formed shape without additional support, making it particularly useful for short transition sections between rigid duct runs. For maximum extraction efficiency, keep the flexible section as short as possible — the 4mm corrugation depth creates more airflow resistance than smooth-walled rigid pipe.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
✓ 125mm semi-rigid aluminium flexible hose — 3 metre length
✓ Hand-bendable and shape-retaining — forms into position and holds without additional support; suitable for firm flexible sections
✓ Not part of the Luxair push-fit airtight system — requires 125mm collar connector and ducting tape at all joints for an airtight seal
✓ 125mm collar connector required — available separately in the Luxair ducting range
✓ Single-layer aluminium construction — 4mm corrugation depth; stated diameter refers to inner bore size
✓ Compressible for transportation — extends to full 3 metre length on installation
✓ Use where rigid ducting cannot be fitted — keep flexible section as short as possible to minimise airflow resistance
✓ Fast UK despatch — express overnight service available
125mm Aluminium Flexible Hose — 1.5 Metres, Fire Retardant
This 125mm aluminium flexible hose is designed to connect directly from the motor unit outlet of a cooker hood to the rigid ducting run above. The 1.5 metre length provides sufficient flexibility to bridge the gap between the motor spigot and the first rigid duct section, accommodating minor misalignments and vibration in the connection.
Fire Retardant — Why This Matters
Aluminium flexible hose is fire retardant and will not melt or shrink when exposed to the high temperatures produced during cooking and extraction. This makes it the only appropriate material for the section of ducting directly connected to the cooker hood motor.
⚠ Never Use Plastic Washer-Dryer Hose on a Cooker Hood
White PVC washer-dryer hose must never be used as cooker hood ducting under any circumstances. PVC hose is not fire retardant — it will melt, shrink, and collapse when exposed to cooking temperatures, creating a serious fire hazard. Despite being the same diameter as some cooker hood outlets, washer-dryer hose is completely unsuitable for extraction use. Always use aluminium flexible hose or rigid ducting throughout a cooker hood installation.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
The 5" Push-Fit System
This hose is compatible with the Luxair 125mm (5") push-fit airtight ducting range. The full system includes rigid round and flat pipe sections, bends, elbows, adapters, and wall outlets. Use ducting tape or a collar connector at joints where push-fit components are not used to ensure an airtight seal throughout the duct run.
Key Features tab:
✓ 125mm aluminium flexible hose — 1.5 metre length
✓ Fire retardant — will not melt or shrink at cooking temperatures; the only appropriate material for direct motor outlet connections
✓ ⚠ Never use plastic washer-dryer hose on a cooker hood — PVC hose is not fire retardant and is a serious fire hazard in extraction installations
✓ Connects directly from motor unit outlet to rigid ducting run — 1.5m length accommodates misalignment and motor vibration
✓ Compatible with the Luxair 5" (125mm) push-fit airtight ducting system
✓ Use ducting tape at non-push-fit joints — ensures airtight seal throughout the duct run
✓ Fast UK despatch — express overnight service available

Available in four colours and three size options to suit any exterior finish and any standard ducting diameter up to 150mm.
Red Dot Design Award Winners
These vents are Red Dot Design Award winners — recognised for combining aesthetic appeal with practical ventilation performance. The louvred face design provides effective airflow when the extractor is running while maintaining a clean, considered appearance on the external wall.
Colours and Sizes
- White (RAL 9010) — 100mm, 125mm, 150mm
- Brick Red Terracotta (RAL 8004) — 125mm, 150mm
- Light Grey (RAL 7042) — 125mm, 150mm
- Anthracite Grey (RAL 7016) — 125mm, 150mm
Select your colour and size from the options above. Check the product title to confirm the exact size and colour before purchasing.
Material and Durability
Constructed from robust synthetic thermoplastic polystyrol — polystyrol does not decay, rot, or degrade over time when exposed to humidity or atmospheric dampness. The backdraft shutter is built into the vent body and operates mechanically — opening under airflow pressure from the extractor and closing when the extractor is off, blocking reverse airflow without any power or maintenance requirement.
Pair With the Luxair Heat Retention Cartridge
For maximum energy efficiency — particularly in airtight or modern fabric first homes — pair these louvred vents with the Luxair heat retention valve. The combination eliminates backdrafts entirely and significantly reduces heat loss through the wall duct when the extractor is not running. Click here to view these.

Rectangular External Wall Vent — 220mm × 90mm and 150mm × 70mm Flat Ducting
This is the correct external wall vent for installations using 220mm × 90mm or 150mm × 70mm flat rectangular ducting. Designed and made exclusively for Luxair, it features a push-fit locking system and a built-in draught-proof non-return internal valve — preventing cold air, wind, and odours from entering through the duct when the extractor is not in use. Available in White, Terracotta, and Anthracite Grey.
Push-Fit Lock System
This vent uses the same patented push-fit system as the Luxair flat ducting range — connecting with an airtight seal and locking securely in place with no ducting tape, adhesive, or fixings required. It is designed to work as an integrated component of the Luxair flat ducting system rather than a generic add-on vent.
Non-Return Draught-Proof Valve
The internal non-return valve closes automatically when the extractor is switched off, sealing the duct outlet against reverse airflow, cold draughts, and wind pressure. The valve opens under extractor airflow pressure and requires no power or maintenance.
UV-Protected Plastic Construction

The Luxair premium round steel wall vent
Please note- the 4" AND 5" VENTS REQUIRE THE CONNECTOR COLLAR
...is a handmade steel ventilation grille for the external or internal termination of a round cooker hood ducting run — available in stainless steel, matt black, white, and anthracite to match your kitchen exterior, render finish, or surrounding fixtures. Built from hand-finished steel rather than moulded plastic, it's a permanent, weather-resistant fitting with an integrated fly screen, available with an optional 100mm or 125mm connector collar to complete the installation in a single order.
Round vs Square Which Wall Vent Do You Need?
Both the round and square Luxair steel vents perform identically and share the same features — the choice is purely about aesthetics and compatibility with your wall and ducting run. The round vent is the natural choice when your ducting run uses round pipe throughout, as the circular profile aligns directly with the round duct and requires no transition at the wall face. It also suits period properties, brick-built homes, and any exterior where a circular vent reads as more traditional or sympathetic to the building's architecture. The square vent suits contemporary rendered exteriors, new builds, and modern kitchens where clean geometric lines are preferred. Both are available in the same four colours choose based on your building and personal preference.
External or Internal One Grille, Both Uses
The round steel vent works equally well as an external wall vent terminating the ducting run on the outside face of an exterior wall, or as an internal wall grille where ducting passes through a partition wall and a finished face is needed on the internal side. The steel construction handles outdoor exposure without rusting, warping, or discolouring — unlike plastic louvre vents that become brittle and discoloured within a few years of UV and weather exposure.
Integrated Fly Screen Insect Protection Built In
Every Luxair round steel wall vent includes a built-in fly screen permanently integrated behind the grille face — preventing insects, wasps, and spiders from entering the ducting run when the extractor is off. The screen is fixed into the vent body rather than being a clip-on component, so it won't fall out, get lost, or be inadvertently removed during cleaning.
Four Finishes Matched to Your Exterior or Interior
Stainless steel is the most weather-resistant option and suits modern kitchens and contemporary exterior finishes — corrosion-proof and low maintenance indefinitely. Matt black coordinates with dark exterior joinery, black window frames, and bold kitchen schemes where a standard white vent would stand out. White is the most versatile choice for rendered exteriors, painted brickwork, white PVC surrounds, and white-walled interiors. Anthracite suits grey render, aluminium framing, and the darker exterior palettes increasingly popular in new build and renovation projects across the UK.
Optional Connector Collar Complete the Job in One Order
Add a 100mm or 125mm connector collar to connect the duct pipe inside the wall directly to the back of the vent grille — the fitting that completes the connection between your ducting run and the vent face. 6" options will fit straight onto 150mm rigid pipe or semi rigid ducting. Ducting tape is recommended around the collar joint to ensure a fully airtight seal at the wall termination point. If you already have the correct collar, select "Not Required". All other components for your ducting run are available as related products at the bottom of this page — add everything in one visit.

The Luxair premium square steel wall vent
...is a handmade steel ventilation grille designed for the external or internal termination of a cooker hood ducting run — available in stainless steel, matt black, white, and anthracite to match your kitchen exterior, internal wall finish, or existing fixtures. Unlike mass-produced plastic louvre vents, this is a hand-finished steel grille built to last the lifetime of your kitchen installation, with an integrated fly screen and a weighted backdraught shutter that closes automatically when the extractor is off. Available with an optional 100mm or 125mm connector collar to complete the connection in a single order.
External or Internal — Two Uses, One Grille
This vent works equally well as an external wall vent — terminating the ducting run on the outside face of an exterior wall, allowing extracted cooking air to exit the building — or as an internal wall grille — used where ducting passes through a partition wall into another void or space and a clean, finished face is needed on the internal side. The square steel profile sits flush against brick, render, timber cladding, and internal plaster equally well, making it the right choice for both applications in a single product.
Integrated Fly Screen — Keeps Insects Out
Every Luxair square steel wall vent includes a built-in fly screen behind the grille face — essential for external installations where insects, wasps, and spiders would otherwise enter the ducting run when the extractor is off. The fine mesh screen is integrated into the vent body rather than clipped on separately, so it stays in place permanently without the risk of falling out or being accidentally removed during cleaning.
Four Finishes — Matched to Your Kitchen or Exterior
Stainless steel suits kitchens with stainless appliances and modern exteriors — and resists corrosion and weathering indefinitely on external walls. Matt black coordinates with dark kitchen schemes, black window frames, and contemporary exterior finishes where a standard white vent would stand out. White is the most popular choice for painted rendered exteriors, white PVC window surrounds, and internal walls with white plasterwork. Anthracite is the go-to for grey rendered exteriors, aluminium window frames, and kitchens with dark grey or slate colour schemes — the fastest-growing finish choice in new-build and renovation projects.

Handmade Stainless Steel External Wall Vent
100mm, 125mm, 150mm and 200mm
These external wall vents are handmade from 304 grade stainless steel — rust-proof, corrosion-resistant, and built to withstand all-weather exterior conditions indefinitely. Available in four sizes to suit standard round ducting systems from 100mm to 200mm. Select your size from the options above and check the product title to confirm the correct size before ordering.
Construction and Finish
Fabricated by hand from 304 stainless steel with a brushed finish throughout. 304 grade is the standard for exterior architectural metalwork — it resists rust, salt air, and UV degradation without coating or treatment. Integrated louvres provide effective airflow when the extractor is running while directing moisture and debris away from the duct opening. Suitable for exterior wall mounting on any standard masonry, render, or cladding surface.
Applications
These vents are suitable for any exterior wall ventilation outlet including kitchen extractor fans, bathroom exhaust systems, utility room ventilation, HVAC and air circulation systems, and dryer vents.

Handmade Stainless Steel External Wall Vent with Backdraft Shutter
These premium stainless steel external wall vents are handmade and feature a built-in backdraft shutter — mechanically closing when the extractor is off to prevent cold draughts, cooking odours, wind, and insects from entering through the wall duct. Available in 100mm, 125mm, and 150mm to suit standard kitchen extractor fan and bathroom ventilation ducting. Select your size from the options above and check the product title to confirm the correct size before ordering.
Backdraft Shutter — How It Works
The backdraft shutter is built directly into the vent body and operates entirely by air pressure. When the extractor runs, airflow pressure pushes the shutter open. When the extractor switches off, the shutter closes automatically — sealing the duct outlet against reverse airflow, wind pressure, and draughts. No power, no wiring, and no maintenance required.
Construction and Finish
Handmade from stainless steel with a brushed exterior finish — weatherproof, rust-resistant, and designed to complement modern exterior wall surfaces. The stainless steel construction ensures long-term durability in all-weather conditions without fading, discolouring, or degrading over time.
Pair With the Luxair Heat Retention Valve
For maximum energy efficiency in airtight or modern fabric-first homes, pair this vent with the Luxair heat retention valve for complete draught elimination and significantly reduced heat loss through the wall duct when the extractor is not in use.

Luxair Automatic Airtight Wall Vent — 125mm (5") and 150mm (6")
The Luxair Automatic Airtight Wall Vent seals shut automatically when your extractor fan is switched off, preventing warm air from escaping through the wall duct and cold air from entering. It operates entirely by air pressure — when the extractor runs, the pressure opens the vent; when the extractor stops, low-maintenance springs return the vent to the sealed position. No electricity, no sensors, no maintenance beyond occasional cleaning.
How It Differs From a Standard Wall Vent
A standard wall vent uses a simple gravity or spring flap that provides minimal sealing — warm air escapes around the flap and wind pressure can force cold air back through the duct into the kitchen. The Luxair automatic airtight vent uses a full perimeter seal on the exterior cover, closing flush against the wall surface for maximum heat retention. Internal guide vanes reduce back-pressure within the duct run, improving extraction efficiency and reducing operating noise compared to a standard vent outlet.
Installation Guidance
For optimum performance this vent is recommended for use with cooker hoods rated above 650m³/hr — the motor needs sufficient airflow pressure to open the vent fully. Use with 125mm (5") or 150mm (6") ducting and keep the total duct run under 4 metres for optimal airflow and heat retention performance. Suitable for airtight and energy-efficient homes where standard wall vents create unacceptable heat loss.

Luxair Small Ceiling Extractor Long-Life Matt Filter — Number 15
If your Luxair small ceiling extractor runs in recirculation mode, the Number 15 is the long-life washable matt filter designed specifically for it. Unlike standard granular carbon charcoal filters which are discarded after 3–4 months, this rectangular filter is washable and reusable — lasting up to 3 years with correct maintenance. One purchase covers you for years rather than months.
Compatible models — select your model from the dropdown above:
- LA-350-CE x 1 filter
- LA-400-CE x 1 filter
- LA-600-CE x 2 filters
- LA-650-CE x 1 large filter
- LA-800-CE x 2 filters
- LA-950-CE x 2 filters
Please note, the above order options are set correctly for your model number. Correctly select your model number and the pricing/amount of filters will be automatically calculated and sent.
If you're unsure whether this is the correct filter for your extractor, use the contact form on this page — our UK-based support team will confirm for you.
Washable and reusable — how it works
The Number 15 matt filter uses regenerated washable panels that can be cleaned and reinstated to full performance. The rectangular flat filter installs easily behind the metal grease filters of your small ceiling extractor.
Clean the filter every 4 months — or every 3 months if you cook heavily — and it will continue performing effectively for up to 3 years and up to 5 wash cycles in total. To clean: either wash by hand using warm soapy water, or place flat in the dishwasher on a low-temperature cycle. After washing, allow to air dry vertically at room temperature before refitting. Do not use heat to speed drying.
Why choose the long-life filter over standard replacements
The Number 15 is the more sustainable and cost-effective choice for small ceiling extractor owners. Rather than purchasing replacement packs every 3–4 months, a single filter provides up to 3 years of filtration with straightforward periodic washing — reducing both ongoing costs and filter waste.
How to install
A short installation video is available on this page — watch it before fitting for a clear visual walkthrough. As a general guide: switch the extractor off, remove the mesh grease filter, fit the Number 15 charcoal filter into position, and refit the grease filter.
Frequently asked questions
How do I know if my small ceiling extractor uses recirculation mode?
If your extractor vents air through a duct to an outside wall or ceiling vent, it is ducted and does not require a charcoal filter. If it has no external duct and returns filtered air back into the room, it is recirculating and requires a charcoal filter. Check your manual or look for a charcoal filter housing inside the extractor behind the grease filter.
Do I need the mesh grease filter with my charcoal filter?
If your existing mesh grease filter is intact and in good condition, the charcoal filter only option is all you need. If your mesh grease filter is damaged, missing, or worn, select the option that includes the replacement mesh grease filter to refresh both at the same time.
Can I wash this filter in the dishwasher?
Yes — place the filter flat in the dishwasher on a low-temperature cycle. Alternatively, wash by hand in warm soapy water. After washing, allow to air dry vertically at room temperature before refitting. Do not use heat to speed up drying.
How many times can I wash the Number 15 filter?
Up to 5 wash cycles over the filter's lifespan of up to 3 years. After 5 washes, the filter should be replaced — performance will diminish beyond this point regardless of how it looks.
Is this the same filter as Number 13 or Number 14?
No. The Number 13 fits the Soffitto, Skyline, Celux and Mille ceiling hoods. The Number 14 fits the Orion Recirculating Ceiling Hood. The Number 15 is sized specifically for the LA-CE range of small ceiling extractors (LA-350-CE through LA-950-CE). Using the wrong filter number may result in an incorrect fit — always check your model code before ordering.
What happens if I don't clean or replace the filter?
A clogged or fully saturated filter restricts airflow through the extractor, reducing performance and making the motor work harder. Regular cleaning on schedule maintains performance and protects motor lifespan.
Does the subscription auto-renew?
Yes — the subscription renews automatically. You can skip, pause, or cancel at any time. Full details are in our subscription policy.
