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.

This is my first whole house fan and I just started using it about a month ago. We have a two story home just under 2600 sq ft. I was concerned it may be too small but it works great! I installed it myself and hooked it up to a 3 way switch so that I could control it off the dimmer downstairs. We just turned it on and it's a good ten degrees cooler upstairs now than downstairs after about 20 minutes. You can really feel the cold air coming in! The only issue I had was that the fan louver cover needs to be a bit smaller. I built a wood frame to dampen the sound and the sides of the cover ended up hitting the frame. I had to notch it out after to make it fit. This is much louder than the Quiet Cool fans but of course it's much cheaper too. I am guessing this will pay us back in a year or so.

I bought this fan to replace a 30" whole house fan that I had installed in August of 1972. It took a bit of custom wood working in order to get this 24" fan to fully fill the space of the original 30" fan, but having just completed the rework as well as fan installation yesterday my wife and I are very pleased with the results. Although this fan moves only 64% as much air as the original one based on its smaller diameter it seems quite adequate.

Have add to order a new bearing assembly which is not expensive. Clearly you get what you pay for. Similar sized units at Granger or Northern Tool are more expensive but probably worth the extra

Definitely does cool the upstairs down quite a bit. The important thing is to make sure your attic can handle the volume. I try to position the fan under the peak and super-sized my gable vents to let all that air out.

Rated 4 out of 5 by from Good Fan We've been debating installing a house fan for a few years. Glad we did. We live in the high desert. Cool nights warm days, and not many people have AC. Perfect climate for a house fan. It has made a huge difference in the comfort of our home. I installed with joist in, constructing the frame of 2x12. I also insulated the box with foam board, and I will build a box of foam to cover the unit in the winter. The fan works great in our 1100 foot home, and this climate. It is a little loud in our small home, but not bad. The on off switch they sent was bad. Oh well. Overall a great investment.

Installation is fairly easy but do put some type of insulation between the frame of the fan and the ceiling. We used a heavy styrofoam product and it helped to keep down the vibration. When we put our hand on the wall under the fan there was no vibration. The square footage of the house we put this in was 1000 sq ft and it totally cooled down the house with windows open in the kitchen, 2 bedrooms, living room and breakfast room. We did not have a window open in the 3rd bedroom or bathroom. The house has no basement so all the circulation was happening from the main floor.
