Airtight Self-Seal Ducting

Please note most of our hoods have a motor outlet of 150mm. You will require a reducer collar to use System100 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.

100mm Round Aluminium Flexi Hose 1.5 mtr

100mm Aluminium Flexi Hose

This duct extends from 200mm to 1.5m.

This aluminium flexi hose is designed to be installed from the top of the motor unit to the start of the flat or round ducting system. Ideally this should be used as it is fire retardant and will not melt or shrink when excessive cooking temperatures are reached.

*You should never use the white PVC washer dryer hose vent kits as cooker hood ducting. They are not fire retardant and are a *fire hazard*

This is part number 2 from the quick link chart.

This clip is part of our System100 range, commonly referred to as 4 inch ducting due to the round pipe being 100mm / 4" wide. This system includes both 100mm x 60mm rectangular ducting and 100mm round ducting as they both have similar airflow rates. We supply adapters should you need to switch between these sizes:
