Air Vent Gable Ventilator 53315 Attic and Whole House Fans, Multicolor,Medium

This fan provided the volume of air flow I needed, and was cheaper and easier to install than typical ceiling-mounted exhaust fans that are available. I used this fan as a hot air exhaust fan in my garage to help get hot air out when hot vehicles are driven in. It is mounted in the back corner of my garage and exhausts into the attic space above. It draws in cooler air from my heavily shaded back yard through a walk-in door in my attached workshop, and helps keep the temperature much more comfortable when working in the shop. I installed with a manual switch in addition to the thermostat so that I could turn the fan on whenever I needed air flow through the workshop and garage. This fan also aids with evacuating any smoke or dust I create in my workshop so serves a dual purpose. This fan avoids having to leave the south-facing garage door open for ventilation and reduces the amount of leaves and other yard debris that otherwise used to blow into the garage, and it avoids having hot air come in from the sun-baked concrete driveway. The fan was of the perfect design for installing in my special application and is reasonably quiet.

There are questions here about horizontal mounting and I will confirm that this fan will run when mounted that way, in a roof (not on a gable). I've had mine installed for several weeks and running almost daily. No problems so far. I will report again if that changes.My previous attic vent fan died after 25 years, and the local big-box construction stores did not have any roof-style models with my size opening (14 inches), only 18-inch or larger, meaning I'd have to cut a larger hole, install new shingles around it, etc. Fun, fun, fun in the summer heat. All I really needed was a fan of the same size with a new motor, which I could install from inside the attic, leaving my old fan cover "dome" in place on the roof.(Mine is old and made of metal, not the plastic kind you typically see on new models today). I took a chance after careful consideration that this item, the Air Vent Gable Attic Ventilator 53315, would fit the bill and it did. It arrived well-packed and in good condition.My roof is not steeply pitched, perhaps 25 degrees, so the fan is not perfectly horizontal but at a slight angle near the peak. I disassembled my current thermostat to "unplug" the old fan (is your POWER OFF? make sure!), then easily disconnected the new thermostat as well, re-connecting the new fan's wiring to the old thermostat. This avoided another step in the installation process (mounting the thermostat at a good location) while crouching in my attic, and I know the old thermostat works fine. You may find it easier to just use the new thermostat.The "wings" with the screw holes on the fan extended nicely past the 14-inch opening in my attic "ceiling", and I quickly drove screws into each of them (check screw length, don't go up through your shingles!) and I had this installed in 30 minutes or so. Before screwing it in place, I put some closed-cell foam pieces, about 1/2 inch thick, which I made from some old packaging material, between the new fan assembly's "wings" and the plywood roofing above. I also put some foam pieces around the disk of the outer fan assembly (I used double-stick tape to hold the foam pieces in place until installed). The foam pieces compressed slightly as I tightened the screws. The foam probably helps isolate vibration and noise. We CAN hear this fan on the floor directly below the attic, but we don't find the noise overpowering or annoying. My old fan was probably out of balance and made quite a bit more of a rumble in the house below.I hope you find this information helpful if you are in my situation needing a roof fan replacement.

Based on reviews, I bought this fan with the understanding that I was most likely going to have to change the thermostat. Electrician friend of mine installed it. It was not the cheapest install; however, the registered temp in my attic was 155 degrees so, had to be done. Hopping over ceiling joists? In that heat was a feat however; he did it. Hard wired the attic; gave me outlets and neatly installed fan. Let me tell you that thing took off spinning and spun all night long without stopping; ran for about 30 hours. Thermostat was set at 78. Outside temp was 96 degrees. We felt the difference in temp at about hour 16. Still hot but didnt feel like our skin was being burned off. We wondered why I'd didnt stop based on set temp. So when my local home maintenance crew stopped by to check my central air ducting and system, I asked about changing the thermostat. He praised the quality of the fan and it's installation and asked why. I explained why. He took a closer look at the thermostat! Moved the dial to 80 degrees and the thing stopped. Oops. He explained that they typically set temps in most unoccupied attics at approx. 90 to 110 degrees. Here I was asking for 78 so it was working towards my 78.It has tripped off and on based on that 80 degrees without issues.Two weeks ago we decided to add flooring to the attic for ease of access and to organize storage. We set it back to 78. On 9. 2.20, I spent four hours in the attic organizing storage. It was 78 degrees outside. Humid. It did not trip on at all. That's when I took the above pics. So far so good. I've seen this at my local hardware store for $116. Worth every penny.Note: I have also hung a regular fan from the big box store over the little triangular vents at the north end of the attic. It does a decent job of hauling in fresh air through those tiny slots. The exhaust fan is mounted on the south end of the attic.

I replaced a similar fan in the top gable of my home. I had to install this one twice, due to noise level when it ran. I could hear it 'rattling' all over the interior of my home. I took it back down intending to return it, but after several tests, I determined the fan blades were slightly loose on the center shaft, allowing it to shake. Simply moved the blades up a a little and tightened the allen screw that holds them to the shaft.Finished the second install and it's working great. Make sure you do it in the early morning, ...dang but it's hot up there!
