Internally Braced
Wind Turbine and Base

A non-electric alternative to ventilation, these vents use the natural force of wind and air pressure to spin and vent out stale attic air. They do it with a series of specially shaped vanes that catch the wind and provide rotary motion. This pulls hot, humid air from the attic. Turbine vents provide a low-cost ventilation alternative in areas where wind speeds of at least 5 mph are typical.

Air Vent's Airhawk wind turbines are available in both internally and externally braced styles
Dual ball bearing system assures long-lasting, quiet operation
Two-piece base fits roof pitches from 3/12 up to 12/12
Large flashing allows for easy installation
Aluminum construction in 12- and 14-inch sizes

Benefits:

Provide year-round ventilation
Low cost and high efficiency make them an extremely popular ventilation component

Design Considerations:

Like roof vents, turbines must always be used with adequate soffit venting to meet minimum ventilation code requirements
Homeowners should not be instructed to cover turbines in winter weather because that would prevent needed ventilation
