Air Vent 17.8 in. H X 20 in. W X 20 in. L X 12 in. D Mill Aluminum Brace Turbine LED INDOOR FIXTURES Fits Pipe Size: 3/4-inchA 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. SPECIFICATIONS Maintenance free dual bearing system
