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 4" Round Ducting Pipe

100mm Round Ducting Pipe 1m

100mm round ducting pipe is ideal for powerful cooker hoods with motor speeds up to 750m³/hr. It is far better at extracting the odours and vapours more efficiently that flexible aluminium pipe.

Using our patented air tight connectors ensures very high extraction without loss of suction and requires no ducting tape on the joint.

This is part number 4a from the chart below.

This clip is part of our 100mm 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:
