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.exhaust-vent-300x225

  • Air Vent’s wind turbines are available in both internally and externally braced styles
  • Patented Delrin® bearings assure long-lasting, quiet operation with no metal parts to squeak

  • Large flashing allows for easy installation
  • Galvanized steel or aluminum construction in 12- and 14-inch sizes
  • Colors: Mill, Black, Brown and Weatherwood



  • 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 ventilation
  • You’ll need to replace your turbine vent when it stops spinning, because properly functioning turbine vents spin with the slightest wind
