Airhawk Aluminum Externally Braced Wind Turbine is 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.

Features:

• Dual ball bearing system assures long-lasting, quiet operation
• Two-piece base
• Large flashing allows for easy installation
• Provide year-round ventilation
• Low cost and high efficiency make them an extremely popular ventilation component
