Duct extractors

Extractors for fitting in the duct: axial, helical, mixed-flow units and ventilation boxes.

They sit in line, between the room vent and the outside outlet. They do not replace a bathroom wall fan.

FAQ

Common questions

Which diameter?

The duct’s. In a home, 100, 125 or 150 mm is usual. Boxes use larger sizes.

In-line or box?

In-line means the motor is inside the tube. A box is the centrifugal unit, for a higher flow.

Can it serve a bathroom?

Yes if the bathroom exhausts through a duct. If the unit is visible on the wall, see bathroom extractors.
