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

These do a great job at keeping my bitcoin mining farm at an ideal temperature. I love that I can monitor them remotely via the WiFi/Bluetooth controller.

Installed in my detached garage to help with humidity and stale air in the summer. Have had it installed one day and it's already doing the trick. The air smells much fresher and it's only been running on level 2/3. Level 7-10 does get a little loud, but moves a ton of air if you need it too. Comes with everything you could need to install except a cutting tool and the caulk obviously. Figuring out how to cut the whole was the hardest part of installing. Was about a two beer job getting it installed from start to finish. The fan itself is very easy to use and seems to just run on level 5 if you don't connect anything else. The app does take a little getting used to. Can be controlled via Bluetooth or WiFi and it remembers your settings when power is disconnected which is nice. Found it much easier to control via the app than with the controller unit. It's a little too easy to click on the wrong setting/button for me. Thought it is a nice display to get the status quickly without pulling out your phone. I am using WiFi to control mine and it is very quick to respond to settings changes made in the app. Which will be good for making adjustments without having to be in the garage. Overall very happy with my purchase. My only wish for it is to easily integrate it with my Home Assistant over WiFi. Maybe in the future the manufacturer could officially support this.

The AC Infinity brand is excellent quality. Durable, reliable, user friendly.I have 3 units total and they all work great. One has been installed for over 4 years, and still good as new.

Specs not mentioned in the description:- The box with the flaps is just under 13.5" (they only provide the size of the circular grill and overall, but if you mount from the inside of the wall you need to know this cut-out size).- Power draw at speed 10 is about 44W, and the power does reduce (sort of linearly) as the speed reduces.- Power draw at speed 0 is 2W (Or about 17.5kWh to leave it plugged in and off all year).- So if you are in a $0.40/kWh electricity area, thats $7/yr to have it installed but powered off.- My old 14" fan was 65dB at 5ft (loud enough to replace it), this 12" is 55dB on speed 10 (loud enough to sound like a loud fan), and very quiet on speed 1 (can't measure dB because background noise was higher). (All this measured with a random phone app).Cons:- Flaps do not fully seal when closed. There is a 5mm gap on the edges. This means bugs and drafts can enter when the device is off. This is a clear design flaw that should be improved.Pros:- Easy enough to set up and get the app and remote working- Its possible to click buttons to manually set the speed 1-10, you dont 'have' to use the automatic stuff- Seems sturdy enough

Can’t say enough about both the Product and the customer service I received from AC Infinity.I bought this the summer of 2021 and installed it in our attic with the controller wall mounted below in a bedroom. I should have done it years ago! The difference in (especially nighttime) home cooling was dramatic! Without this powered ventilation, heat would radiate downward from the hot attic all night making sleeping difficult. Now, soon after the sun is down the digital readout from the attic sensor shows how quickly all that heat is exhausted and we can definitely tell the difference with cooler home temps.Then, this spring when I went to turn it back on, I couldn’t get the controller to come alive. An email discussion with the mfr AC Infinity followed, with them sending an entire replacement unit after we couldn’t fix it with troubleshooting. And they shipped it right away.When detaching the old controller, I noticed that the 4-pin molex connector had been turned around and plugged in backwards! After reversing, it all came back alive. So the product wasn’t even defective in the first place!Since we AirB our place occasionally, I’ve deduced that likely a guest did the swap thing one day when the high temp alarm was beeping and didn’t say anything to us. Fortunately, the alarm feature can be programmed “off”. So I learned my lesson to not use the alarm feature with guests.Good product, comes with all the wiring, fasteners, etc and well-written instructions. And is backed with responsive customer service that responded and acted quickly. Very rare these days.Highly recommend!

We have a small laundry room in the middle of the house and with no way for heat and humidity to escape After researching what my options were. We decided to place the exhaust fan into the wall into the garage. The vents open and close as needed, and we also weatherproof it to keep out little critters. It Worked! Much less heat and humidity A PLUS. with the app and program it runs automatically

I love the automatic fan speed feature, it's nice to have it nice and quiet most of the time, but when it reaches my setpoint, I can have it turn all the way up to 10, by whatever temperature or humidity increment I want. And it moves a ton of air when it's turned all the up. When it's on 4 or lower, my ears can't even tell that it's on; I only feel the air moving.
