Active cross-ventilation: every room breathing in and out, driving out damp and humidity for good.
The Active Vent range uses the same physics that lifts an aeroplane wing to pull humid air out of your walls and every room in your home — continuous cross-ventilation with no fans, no wiring and no running costs.

Cleaning mould isn't fixing it. Removing humidity is.
Only cross-ventilation drives humid air out of a room. Until now that meant a powered fan plus a passive vent. Active Vent does both jobs in one unit — its own air inlet and exhaust, powered by wind.
One technology. Every part of the building.


The same physics that lifts an aeroplane wing dries your walls.
As wind passes the vent, it speeds up through a narrowing channel and creates suction — actively pulling humid air out while fresh air is drawn in through a separate inlet. Continuous cross-ventilation, powered entirely by nature.
Active Vent is the world's first, patent-protected wind-powered cross-ventilating vent.
Engineers call it the venturi effect.
