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

I would give this 10 stars if I could. So far I've only set it up in the living room and tested the functions, but it is an amazing product with loads of functionality. I'm using this fan to ventilate a crawl space. I went with this product for the App functions as I wanted to avoid pulling in moist air on humid days. With the controller I can set the fan to only cut on when outside humidity is low. It can also be used for high humidity days if you were using it to vent a greenhouse for example. I've also set the temperature parameters so it will cut off if temps fall below 40. It has 10 speed settings for the fan but even at 10 the fan is not loud at all. I have full control through the App, the controller unit is connected to the wifi so I don't have to get down in the crawlspace to adjust anything. I will follow up with install pics and performance feedback but as of now, I could not be happier. When the fan is not running the shutters stay closed to keep out critters and cold air. I expect drastic changes in the crawl space humidity while I address water ingress issues on the exterior. I tried a 120 pint a day dehumidifier that didn't touch the humidity levels. Taking advantage of dry air days outside should make a huge impact in the crawl space humidity levels. This thing moves some air.

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).

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 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.

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.

works great 1 year later, still rockin!

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

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!

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.

Fan is effective and quiet. Great wifi and app for control. Auto schedule based on time or temperature. We have it in a shed for our smoker and bbq. Love this!

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

C est quand même assez bruyant , mais performant
