AC Infinity AIRLIFT T12, Shutter Exhaust Fan 300mm with WiFi Temperature Humidity Controller, EC-Motor Wall Mount Ventilation and Cooling for Sheds, Attics, Workshops, and Greenhouses, 12-Inch

Very impressive product - extremely well packaged and engineered. Pricey - but you get your money's worth in the quality and attention to detail.

I have a 12'x10' dark brown Tuff Shed that can get pretty hot in the summer months. This exhaust fan can lower the ambient temperature by 10-15 degrees. It's well made, quiet and easy to install. I had no problems in the 7 month since I installed it.

We had an attic that was heating up quite a bit. Decided to try one of these exhaust fans to see if it would do anything. Installation was easy. Cut the hole - put it in - plug it in. It has both a wired remote (so you put the fan in a wall in your attic, and put the controller closer to the attic access so you can change settings manually without having to go fully into the attic) and a Phone App (Android and Apple) - so controlling it is a breeze. I have mine set so that if the attic gets above a certain temp it comes on and blows the hot air out. I was debating about how much of a difference this would actually make - but it really does. It lowers the temperature 4 or 5 degrees with 20 minutes. Very impressive. I am able to check the temp in the attic at any time - and turn it on/off via my phone if I want (as well as the automatic on/off settings by temperature). Highly recommend this device!

I bought this as an exhaust fan for our greenhouse . The fan itself is very well designed and solidly built. The control unit is very nice and very easy to program. Good cabling and a great supply of mounting hardware including various nuts. bolts screws; even cable ties with adhesive fasteners. The fan installs easily and is very quiet. I have it on the high temperature cut in setting and it works flawlessly. The temperature probe is very sensitive. Set at 21C it kicks in immediately when the temperature hits 21 and exhausts air quickly enough that the greenhouse temperature drops almost instantly and the fan cuts out again. A quality built product. Would recommend to anyone.

Very simple yet innovative system for automating the flow of air for temperature and humidity control, remote sensing and monitoring in a durably constructed solution. Takes a lot of effort out of having to manually inspect conditions and absolutely confidant these will last for many many years. Firmware updates are simple, not nail-biters and no worries about any aspects of the units failing. Spoiled chickens for sure.
