Rooftop Ventilators/Cyclone

A roof turbine cyclone is a rotating vent that spins when wind passes through it. The spinning action creates a suction effect that draws warm air, moisture, smoke, or dust out of the building through the roof — without using electricity. - How It Works 1. Wind hits the turbine head, causing it to spin. 2. The rotation creates a low-pressure zone inside the ventilator. 3. Hot or stale air from inside the building is sucked up and expelled through the vent. 4. Cooler, fresh air enters through windows, doors, or wall vents — improving ventilation naturally.
