I could not reach my gable area of the home as it was too tight. My home has four (4) existing static air vents that are about 14 inches in diameter in the roof of the home so that air can naturally flow up from the vents in the eves and out the roof by simple physics of heat rising. But that really is not that optimal and never has been for any home. I have searched for any forced air electrical unit that could be installed below one of those static vents and force a lot more air out of the attic through the roof. There is nothing on the market. I am an engineer, so I just took the time to research enough gable vents to find the right one and this is it. What is important to know is that most gable vents have a high CFM (Cubic Ft Per Minute) of airflow of around 1600-2500. Forcing that much air into a static roof vent will cause a venturi effect due to the inability of the roof vent to accommodate that much air flow. This actually causes more noise. This is why I chose this unit. Much smaller, 820 CFM, easy to install and comes with a rheostat to control the speed of the fan in case the existing static roof vent cannot accept that much air flow. I found that the unit works just fine on full speed of 820 CFM and there is absolutely no noise at all. The unit is ultra quiet. If anyone plans to do the same thing I have done, just get the unit without the rheostat and only the thermostat and save the money. It will work without any noise if you have a decent size existing roof static vent. IMPORTANT INSTALL INSTRUCTIONS: In order for this to work, you will need to install two 2 X 4's between the roof joists 10.5" inches apart and centered over the hole that was cut for the existing roof static vent (photos included). Then two more 2 X 4's between the two I just mentioned, and once again, 10.5 inches apart and centered over the existing hole for the static roof vent. This creates a 10.5" inch square box. The 2 X 4's need to be mounted upright (not flat) so there is a 3.5" inch deep square to insert this new attic fan. YOU MUST REMOVE THE AUTOMATIC SHUTTER that comes with the fan. Very simple and only has 3 screws that hold it in place on each side of the fan. Now you have just a fan and a square metal box that holds the fan. Screw that metal box into the 10.5" inch wooden square you framed as mentioned above. Then plug the unit in using the 6ft long cord and you are done. If you do not have a plug nearby, you can use an extension cord. But the extension cord should be a 3 prong grounded plug since the cord that comes on the fan is a 3 prong plug. I have enclosed photos. Very easy to do and took me less than an hour start to finish, and I also ran wiring and installed an outlet to plug into. One of the photos is of the rheostat that comes with this unit. It has a 3 prongs on the rear to plug directly into an outlet and the cord from the fan plugs into the bottom of this rheostat. The manufacturer of this unit give you no information to know that or the length of the cord, among other things. This is why my review is so long. Now you should know everything so you can do this yourself. My plan is to add another one at the other end of the house since the home is quite large. Already making a difference in the amount of heat in my attic.

I installed this fan in my attic to replace an old crusty fan that was seized up and it's been great.I put it in in 2022 and it's still going quiet and strong.The controller is great, simple and works perfect.

This fan not only works great moving air but it's even quiet at its max speed. And it comes with a temp/speed controller too which is amazing at this price point.

This is the third time I purchased this fan. I keep replacing it because the hole is already in the shed and it is easiest to keep replacing with the same unit. I am in Southern California and it can get above 100° F in the summers. First installed in 2020, exactly two years later I replaced it in 2022. Now, two years and a month later, time for number three. It is a good fan, just costs me $50 a year to replace. I will do a little research and buy a more robust product in 2026. I see other reviewers state their fan lasted longer, not sure why. I will budget more for two years from now (if it indeed lasts that long) and save climbing up the ladder in my workout shed if a "better" unit can last longer. Not too bad, works well as long as it works until the motor seizes.

Fan works great in the She-shed. Adjustable speed and temp. It actually works. Runs most of the day in Florida but does a good job at keeping the temp down in the shed and shuts off in the evening. Boxed up good when it came in and had the destructions with it. Pretty simple installation for the most part. I will recommend this unit.

The Horsepower is good, quality of the housing and switches are good, weight of the metal tells you it is sturdy. Fit is great and conforms to the measurements described in the listing. Nice deal and dependable product that moves the air through my garage.

Works great, makes a world of difference. Ended up using a different thermometer but the included one seems good. The one I am using allows for "smart" control so I don't need to go in the attic to change it (because I can't). As you can imagine, I want it hot up there when it is winter. Ran this through a GFCI for safety and it's been keeping the 2nd floor significantly cooler, and it is not very loud at all from inside. I can hear a slight hum.

With a west facing metal garage door heated my garage to 120 degrees. Install this fan in my garage wall and temp dropped 25 degrees! Wish I had done sooner! Like the 3 speeds and thermostat control! It's very well made!

Pour transfert d’air chaud de l’atelier à la salle mecanique

I purchased 2 of these units to install in my Cottage. One mounted inside the cottage on the wall to extract air and the the other in the Cottage Attic where one of the exit vents was located. I am not at the cottage often and I want fresh air all the time, so, I crack the windows at one end of the building and the fan is mounted in the wall at the other and I have it set on a timer. I should have thought of this years ago. What a difference in air quality when I arrive at the cottage. So far, so good. The bearings are holding up and the fans still run like new.

I have been running this fan almost constantly for one year now to vent out my garage to avoid humidity and it works great ! Nice and smooth and if it fails, it's cheap and I'll just throw another one in. Looking to also put one in my attic to vent out the heat in the summer.
