Airtight Self-Seal Ducting 

Please note most of our hoods have a motor exhaust of 150mm. We supply reducer collars should you need to use smaller ducting.  

We highly recommend using the largest possible size ducting on every installation to maximise air flow. 

Please check each product specification guide to determine what size duct you require.

150mm To 125mm Ducting Reducer Collar

150mm to 125mm Reducer Collar

This reducer collar is used to reduce the ducting size from 6" to 5" ( 150mm to 125mm)

This part is used as a connector from the top of the motor housing spigot to round 125mm ducting.

This reducer is part of our Airtight 6" range, commonly referred to as 6 inch ducting due to the round pipe being 150mm wide. This system includes both 220mm x 90mm flat ducting and 150mm round ducting as they both have similar airflow rates. We supply adapters should you need to switch between these sizes:

Round to Flat Adapter 

Round to Flat Elbow

This is part number 1 from the quick link chart.
