Air Vent Air Hawk 18.4 in. H X 12 in. D Weatherwood Aluminum Turbine and Base

Wind Turbines are a type of attic exhaust vent that make up half of a balanced attic ventilation system for each roof. Intake vents make up the other half of the system. Together they help remove any built-up heat and moisture inside the attic for year-round ventilation. A non-electric alternative to ventilation, turbine 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. Brand Name: Air Vent Sub Brand: Air Hawk Height: 18.4 in. Diameter: 12 in.
