24 Inch Direct Drive Whole House Fan with Shutter - HUB Model

Product code: 356

Availability: In stock

Quick Overview:

Now control your fan using WiFi! The Cool Attic 24 in. direct drive 2-speed whole house fan is designed for houses with 1,200 to 1,800 sq. ft. attics. It offers 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.

This unit requires a minimum of 8-10 sq. ft. of net free exhaust vent area to perform correctly. Low vibration direct drive design and a 4-blade galvanized steel fan assembly contribute to quiet and reliable performance. This fan operates over WiFi using our WiFan app, available for download from most smart devices.

NOTE: Whole House Fans should not be used as exhaust fans. If you are seeking an exhaust fan, please see the Industrial Exhaust Fans catalog.
