24 In. 2-Speed Belt Drive Whole House Fan with Shutter and Wi-Fi Controls

Quick Overview


Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our belt drive units have been engineered to offer a superior performance with a more stable motor mount that is stronger than typical tube-style bracing and virtually eliminates vibration alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your ceiling. Install as a joist-in or joist-out configuration and control the unit from anywhere in your home from your smart device. Whole House Fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents. Save on energy costs by taking advantage of the timer setting available only on Wi-Fi hub units, which will automatically turn off your unit after your desired time setting has been reached.
