Green-Vent Wind — Wind Driven Roof Ventilators

The Green-Vent Wind is a premium wind-driven roof ventilation system developed using Australian engineering and manufactured locally in the Philippines.

Designed to operate without electricity, the Green-Vent Wind uses the natural energy of wind to continuously expel hot, stale air from within a building — replacing it with cooler, fresher air from outside. Even minimal wind speeds are sufficient to activate the system.

With a 15-year manufacturer's warranty and a proven track record in demanding Philippine conditions — including heavy monsoon rainfall — the Green-Vent Wind is one of the most reliable roof ventilation solutions available in the market.
