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. All the components needed to complete your run are available as related products at the bottom of this page — add everything to your basket in one visit without having to search for each part separately.
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
