OPTI-T412

Replacement for Turbine-type Vent (Whirlybird) 



The turbine-type ventilator has always been a popular choice for roof ventilation. This design requires the help of the wind to operate but over time it is rendered useless by snow and rust.The OPTI-T412 is designed to replace the turbine on an existing installation without altering the aperture. It settles directly on the old round base already in place thanks to the adapter of 12 inches (30,5 cm) in diameter.The openings from the ventilator structure eliminate any need for long-term maintenance and prevent the intrusion of birds or rodents. The static ventilator promotes higher suction and, using the wind, produces a chimney effect. The air is exchanged continuously. It exchanges air at a frequency of 418 cubic feet per min, covering an area of 1000 to 1200 sq. ft.
