Active Vent
PATENTED WIND-POWERED VENTILATION — NO ELECTRICITY, EVER

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.

✓ Continuous cross-ventilation ✓ Retrofit in minutes ✓ Works in sealed rooms ✓ 100% recycled option

WHY MOULD KEEPS COMING BACK

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.

PASSIVE TRICKLE VENT
✗ No extraction — air drifts, humidity stays ✗ Mould returns after cleaning ✓ Cheap
EXTRACTOR FAN + VENT
✓ Cross-ventilates — when switched on ✗ Needs wiring, maintenance & electricity ✗ Gets turned off
ACTIVE VENT
✓ Continuous cross-ventilation, 24/7 ✓ No power, no wiring, no running cost ✓ Works in sealed rooms & HMOs — can't be switched off

THE TECHNOLOGY

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.

01Wind hits the vent face and accelerates through the channel
02Suction actively extracts humid air from the wall or room
03Fresh air flows in through the inlet — humid air is continuously drawn out

Engineers call it the venturi effect.
