ATCO Airvent Turbine Ventilators

Ridge & Downslope Roof Ventilator allows hot air to escape through the vents while preventing cold air and moisture from entering. The ventilator works by using a combination of wind and thermal actions which the wind creates a vacuum effect that pulls the hot air out of the attic.

Airvent Turbine Ventilator operates by utilizing the velocity energy of the wind to induce air flow by centrifugal action. The centrifugal force caused by the spinning vanes creates a region of low pressure area which draws air out through the turbine. Air drawn out by the turbine is continuously replaced by fresh air from the outside. Suction is maintained even at low wind velocities.
