This system includes both 220mm x 90mm flat ducting and 150mm round ducting as they both have similar airflow rates. The 1m venting kit is suitable for high power hoods and extractors with air-flow in excess of 500m³/h. This 150mm diameter vent pipe is suitable supplied in 1 metre lengths and suitable for all 150mm diameter venting systems with a round connection. This adapter is part of our System150 range, commonly referred to as 6 inch ducting due to the round pipe being 150mm wide.

If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space.

Will comply with Building Regulation Part F if installed in accordance with the manufacturer's instructions and by a competent person. This venting adaptor allows connection between 150mm diameter round pipe or flexible hose and 220mm x 90mm flat channel box section ducting or flexible PVC ducting.
