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, while keeping your whole house more comfortable. It works by pulling fresh air in from the outside and expelling the warm air up into the attic and pushing it out through your attic exhaust vents. This unit requires a minimum of 8-10 sq. ft. of net free exhaust vent area to perform quietly and efficiently. Low vibration direct drive design with a precision-balanced 4-blade aluminum fan assembly contribute to quiet and reliable performance.
