1,200 - 1,800




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. 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.

In our pursuit of constant improvement, our belt-driven whole house fans are constructed using a re-engineered bracing system to eliminate excess vibration that not only offers a quieter operation in your home, but is stronger than traditional tube-style bracing.


Our whole house fan line features a shutter that opens and closes automatically with the fan's operation, making startup a breeze. In winter when the fan is not in use, the shutter maintains a 95%+ air closure to keep heated air in your living areas and out of your attic space.

Whole house fans use open windows and doors to cool your home.

Whole house fans pull cool air from open windows and doors throughout the house and push stale, warm air upwards to escape through your attic, making them a perfect alternative to an air conditioner in moderate climates. Feel instantly refreshed with this energy-saving cooling measure!

Our whole house fan line is designed to work with joist-in or joist-out install methods. Your fan arrives with an easy-to-follow instruction manual and quick start guide to make the installation process simple. This fan is 14 inches high.
