AC InfinityAIRLIFT S14, Shutter Exhaust Fan 14” with 10-Speed Controller, EC Motor - Wall Mount Ventilation and Cooling for Sheds, Attics, Workshops, and Greenhouses

Came packaged well, installed easily, and everything works. Should help out alot in the chicken coop. Only complaints from the install:1. The screw heads provided are not a standardized size so you will have to use a Philips bit. You'll understand when you go to secure it. I ended up using something else.2. There isn't much space between the fan cage and the mounting holes so you'll have to be precise on your rough opening.**I'll update if there are any problems.

I used 4 of these in my attic in an unconventional way - I do not have a gable but I do have the typical square vents in my older roof. I mounted them under 4 of those vents. yes 12's might have been a better fit but I went with the 14's to run them slower for less potential noise. I also took the time to properly wire 4 outlets for the fans which the power feed came from the one attic light that the house had. If you do this take the time to do it right for safety sake!I took the shutters off since these would be mounted on a 45 degree angle and mounted them to the the studs on the roof and boxed it in with 2 other 2X4's connecting the existing studs. it seals it well enough against the roof vents. I picked these because they could be mounted on an angle and because they have efficient motors which will pay for themselves in a short period of time.I have a 3130 sq house with a mostly 1st floor layout so there is a lot of roof that all the heat goes right to the 2nd floor and right above the 3 kids rooms. There use to be a wall of heat you would hit when going up the stairs and no amount of vent boosters in those rooms would help. Now with these 4 fans running we no longer have that issue and the A/C runs less. I only run the fans on half speed because they are blowing through a vent that is smaller than the fans and running them full speed would just create noise and extra power draw for no reason. I've been waiting on the Wifi controller to be available again but I might just get the bluetooth one for now so I can play with the fan speeds through out the year and not need to go into the attic. I'm VERY HAPPY with these purchases!

This fan does the job! It moves lots of air and is not as loud as expected. Great product. I am going to get one for the attic.

I bought this to pull the hot air out of our condo in the summer. Works awesome for that.I knocked a star off only because the shutters don't fully seal off, so you need to add a screen to keep bugs from getting in.Very glad I bought it.

Great product. Well made, noise level is tolerable but may be difficult to live with if in an environment such as a basement play room or TV room. In a garage or shed no problem. The kit comes with everything you need for mounting. I mounted in our garage and am really impressed with the air flow this product generates. At the 8 speed level it's actually hard to hold your hand against the flow of air from its suction power. At the 4 speed level it's much quieter but no less efficient. Thoroughly impressed and happy with the purchase.

Air flow and value for money.

I use this as an exhaust fan above my drop ceiling in a building without windows that can be opened. It drops the temperature over 6 degrees in my case, allowing AC to work less hard, less often. Well worth the money. The star ratings are confusing: I gave 5 stars because there is LITTLE to no noise. It was super easy to install (45 minutes after opening the box to finish).

I was shocked at how much air this thing can move. I actually use this in a window. I removed the louvers on the front, fit it into my window, and used a piece of that foam presentation board cut to fit and closed off the rest of the window. Opened a couple windows in the other part of the house, and turned this on medium. I could feel a pretty strong breeze going through the house. Both open windows had a lot of air coming through, so my windtunnel hopes paid off.I have always used ac infinity fans to cool my home entertainment center equipment, but this was my first experience with something larger than a 140mm fan from them. As usual, they delivered.
