What is an inline duct exhaust fan 100mm?

An inline duct fan sits inside a round duct run, pushing or pulling air through it. Its round inlet and outlet match standard duct sizes, commonly 100, 150, 200, 250 and 315 mm.

Mixed-flow and centrifugal designs give enough pressure for long ducts, grilles and filters. Metal-cased fans suit warmer or tougher sites, while PVC-cased fans are light and resist moisture.

Key terms explained

Mixed-flow fan: A fan between axial and centrifugal, giving good pressure in a compact round case.
Duct diameter: The round duct size the fan connects to, such as 150 mm.
Airflow (m3/h or CFM): How much air a fan moves. 1 m3/h is about 0.59 CFM.
Static pressure: The resistance a fan must push against from ducts, filters and grilles, in pascals (Pa).
Air changes per hour (ACH): How many times the air in a room is replaced each hour.
