AC Infinity, AIRLIFT S14 Shutter Fan 14”, with Speed Controller

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!

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).

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.

Bought this for my attic to help cool it down in the hot months. It’s only late March so I can’t speak for actual summer temps yet. It does lower the temperature and I hope it will be enough for the summer. This is a 14 inch. it’s dark outside so I didn’t go take an exterior picture. For the price, I sure hope it works for many years to come. It’s not exactly quiet, but it’s not annoyingly loud. I’m OK with the volume inside and outside the shutters. Always close when I turn it off, as I they should. It’s been a little over a month. Will know more in the coming months. .

I bought two 14” smart fans for our greenhouse. They are of great quality and are packaged well. Fans were easy to install and come with heavy duty screws so fans are secured to the wall with no vibration. Fans are a little loud on the highest setting, but controls the temperature well and provides good air movement throughout the building. The black looks sharp from the outside. I highly recommend this product.

great fan. I ave had this fan for 4 years and it still works great and is wisper quiet .

I don’t typically leave product reviews but I want to - especially for those using these to for greenhouses. I almost bought a cheaper manual or basic temp controlled fan, but after looking into the smart controller I figured I’d give it a shot. Once I started to configure the fan I saw options for temp, humidity, and VPD triggers. VPD is a function of temperature and humidity which is important for a healthy greenhouse environment. High VPD equates to high levels of respiration (making plants prone to burning from the sun and nutrients), low VPD is low respiration (putting plants at risk for root rot and pests). Even with a humidifier in a greenhouse high VPD is easy to run into during the day, but so is (obviously) heat. At night low VPD prevails where heat typically isn’t an issue. So by setting temp triggers during the day and VPD triggers at night, VPD continues to stay in acceptable range. The UI in the AC Infinity app is also intuitive and well-thought out. I am impressed!

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 = OFF 60 = speed 1 65 = speed 2 70 = speed 3 75 = speed 4 And so on to 10 Very 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

On time and as described

Humidity sensor worked great in the garage to turning on fan only when it is humid.

working great, cooling our super hot attic. Not entirely silent, but not noisy. The app is useful to assess the humidity and temperature so you can time the fan cycles. Recommended to us by our electrician.
