Maxx Air, Cool Attic |

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 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!
