AC InfinityAIRLIFT T14, Shutter Exhaust Fan 14" with WiFi Temperature Humidity Controller, EC-Motor Wall Mount Ventilation and Cooling for Sheds, Attics, Workshops, and Greenhouses

Innovative design, simple to install, love the phone app, customization features and expansion options. While I assume this system was originally designed for grow houses, I installed in my home attic to control temperature and humidity and its works reasonably well. The fan is lightweight and decent quality and reasonably priced. My only suggestion to the company is to allow for an external thermostat so that you measure the difference between internal and external temps (caveat being that you may already be able to do this and I am just not aware of this feature).

Great fan. Does what it needs to do very well. Took me a week to figure out I needed to create an automation for the variable fan function. Basically fan turns on/off at 60 degrees. Every 5 degrees increased it'll step up in fan speed. So for example:[Degrees]59 = OFF60 = speed 165 = speed 270 = speed 375 = speed 4And so on to 10Very happy and ended up buying the house fan, carbon filter combo and a couple other items. All high quality.I originally got an inline for my laser a couple years ago that has been issue free

We have an operable skylight in the second floor ceiling with a screen, an ideal place to install a vent fan. The 14" was the largest that would fit. I built a mounting frame out of 2 x 3s with plexiglas panels to keep the air from backflowing where the fan didn't cover the skylight opening. The fan is tilted about 25 degrees up from horizontal (the roof slope). We use it at night when it gets hotter than 90 F outside during the previous day, are able to cool the house down to the low 60s in the morning. So far this summer have been able to avoid using the A/C, saving $$ on electricity. Our house is 1800 sq ft. The temperature control prevents it from over-cooling the house. The fan is in a room next to our bedroom, and we can hear it, but it's not an unpleasant sound (kind of white noise) and doesn't interfere with sleep. The display is easy to read, and the controls have a lot of options and are easy to use. We run it full speed, when speed gets 60% or lower the louvers don't open fully and can chatter. If the louvers had an actuator to open fully anytime the fan is on, it would make the speed control more useful. Also for installs in living areas where it will be seen, it would be better if it came in white. Highly recommended.

I had mine installed by an electrician (with a very tall ladder) a year ago and I can say that for keeping the attic cool, it works great. The motor kicks in at 90 degrees and is mostly quiet other than a gentle hum. No problem there. My problem is that the wind is so strong at times it causes the flaps to fling open and closed loudly and it can be heard from the bedrooms. The only thing i have been able to do is fashion a hook to slip through the metal protection around the fan to hook onto a flap to keep them closed in the winter but in the summer i seem to be out of luck.

Built a cedar box to clear the blades when fully open and works great. Great quality and very cool features with easy programming. Barely pulls any electricity and with some vents keeps the attic flowing.

This works like a charm. Easy to operate and put in. My roof vents don’t work well because they covered the openings with felt. The attic would become boiling and cause the second floor to become so hot during the day. Installation was simple. Had to install a plug in the attic for the wire but other than that it was simple to set the high temp limit and watch it turn on when it hit the temp and then turn off when it reached below the limit. A must have for any attic space!

I have two different models of AC infinity fan love them both. They are loud a full speed but move a lot of air. One of the fans I have had for 3 years and runs almost 24/7 with no issues.

Easy to install with a few basic tools. APP control is easy to use and much easier to monitor attic conditions.
