Product Overview

The cool attic 24 in. belt 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. Dual, self-aligning ball bearing mechanisms, and precision-balanced 4-blade aluminum fan assembly, contribute to quiet, reliable performance and longevity.

Customer Questions & Answers

Does anyone know if normal operation is for the fan to only turn on when speed switch is set to high?

Just had this whole house fan installed and the installing is telling me that the fan will turn on only when the speed switch is set to high? When the switch is set to low and the power switch is turned on the fan doesn't turn on. Is this normal operation for this fan? I had a whole house fan in my previous house and it was able to start in low. The installer is ensuring me that it was installed per the mfg'ers instruction. So maybe I have a faulty fan? Thanks for your help.
Asked by: wrbird
I have the same fan as you do - installed it a couple months ago. It turns on from both low and high speed switch positions. Guessing that your switch is either wired incorrectly, or it's bad.

Can I use a variable speed control wall switch for this? Or at least a 3-speed switch?

I'd like to know if an option for a lower setting for the fan to run on is possible. Thanks! Also, is this the Cool Attic brand fan?
Asked by: Jenna
The fan comes with a 2-speed motor and a 2-speed switch. A 3-speed switch won't work on a 2-speed motor, and a variable-speed switch would be unsafe (as in potentially damaging the fan and/or starting a fire).

Exterior wall mount

Can this mount on wall and is this rain resistant
Asked by: rdmpiolot
While technically the unit could be mounted on a wall, it is not designed for such and would probably void any sort of warrant. It is NOT weather resistant. It sounds to me like you are looking for something more like an attic exhaust fan that mounts in the side wall of an attic. Those would be designed for a vertical installation and would be weather resistant.

Can a Master Flow 12-hour timer be used with this 24" whole house fan?

Asked by: Robert
Absolutely yes. I've installed 3 of these fans in my last 3 houses - complete with timers. Just install the timer in line with the hot (black) wire that's coming from the circuit breaker.
