AC Infinity AIRLIFT T16 Roller Shutter Extractor Fan 16 Inch with Temperature Humidity Controller - Wall Mount Ventilation and Cooling with WiFi Integrated App Control for Sheds, Attics, Workshop

This is a very good fan. I am installing it in my attic. I put 2 vents on the opposite side of the attic and this will draw the hot air from the attic. I temporarily installed it but I am amazed at how quiet it is. I like the controls and I still have to install the bluetooth app. I was going to finish the install today but I am too sore after being on a steep roof for 3 hours. It is also 98 degrees and a black roof. I am 73 so I do not have the stamina as a younger me. I have to install a receptical for the plug and drill a hole in the ceiling for the probe and the control cable. I am highly satisfied with the purchase. UPDATE===I have it installed now and it works great. I bought 2, 12 inch vents for the north side of the attic and installed this fan on the south end. The attic temps were running between 135 and 140 in the afternoon. Now with this insatlled it was 110 degrees in the attic and it was 102 degrees outside. Very very satisfied.

This product moves an unbelievably large quantity of air (The 16 inch model with Bluetooth Controller) for a very small amount of power comparably. The controller has lots of options to customize the operation to your needs, including limits on temperature and humidity. The specifications indicate that it produces 70 dB noise level at the installation location, which is not insignificant, and should be expected and planned for in a fan this size. Measured noise levels 1 floor below my attic is about 40 dB (audible, but not overly bothersome). Bluetooth control is implemented very well, and works reliably within range. Speed controller provides 10 different speeds electronically (i.e. efficiently). Build quality is evident at first inspection. Would recommend this supplier.

Installed in the house attic (2,900 sq ft footprint). Moves air very well. The WIFI controls are a super to avoid trips to the attic and no wiring other than power is needed.

This fan was a reasonable install although my husband had to build a frame to mount it as our house. Just didn’t configure properly. He also ran the wire through a tiny hole he drilled so the readout is in our mud room where we can see it. Then he had to call and speak to someone in order to program the screen because the instructions are difficult to follow. The guy on the phone was super nice and helpful so customer service gets 5 stars. We love that we can program it, we love that it is super quiet when we’re in the house. Oddly, while it is much quieter from inside, it is actually louder than our 50-year-old fan was outside. When we sit on our deck, it is noticeably louder but not terrible. Since the readout/monitor is right in our mud room, we can easily adjust it when we want so it has been no problem. We are very happy with this fan, it is keeping our attic much cooler. When it is about 85° outside our attic goes up to about 130° without a fan and with this fan it brings it down to105°. Had it about 4 months, so far so good.

I installed this fan in my new greenhouse. The controller is great with WiFi and able to program the fan based on greenhouse temperature. I have since added two interior fans on the same controller one smaller clamp on fan land one floor fan. Could not be happier with this purchase, they have been working continuously without issue. Well built, good quality products.
