AC InfinityAIRLIFT T20, Shutter Exhaust Fan 20" with WiFi Temperature Humidity Controller, EC-Motor Wall Mount Ventilation and Cooling for Sheds, Attics, Workshops, and Greenhouses

I have 3 work incredible well. The app is easy and works awsome

The media could not be loaded. We have installed these in Commercial environments and they were great no problems at all even running every day all day. Very good controller. Built very sturdy. No complaints good pricing.

I have several of these fans and they work great with the included controller. I installed in my attic and it keeps the heat lower. My AC unit is in the attic so it helps it run more efficiently.The WiFi controller works really well with great features to adjust Temps for when the fan will activate and ramp up with increase of temps.

High quality product!

Not only are the louvers not moisture resistant as they advertise, but there is a 1/4" inch gap all around them, so now I guess I get to watch my wall rot from rain damage. Their product support suggested that I build a roof over the louvers to minimize the rain damage. Their support is a joke. Do not buy this product if you are penetrating a wall to the outside. Find a better engineered brand. Junk louvers!!! Just slightly better than leaving a 20 inch hole in the side of your shop

I’m extremely impressed with this fan system! This product is crafted exceptionally well resulting in a prestigious, high-end experience. The fan is very well made with heavy-duty construction/materials- you can tell that it’ll last for a long time.The instructions are super clear as well, and easy to understand with all the physical parts clearly marked and packaged.The highlight of this product is the digital fan controller. This controller allows you to quickly and easily set your fan to function exactly as you’d like, and then let it take over for you. It can detect both temperature and humidity (using the included extra long wire probe), and turn the fan on or off once the humidity and/or temperature thresholds you set have been passed, both at the minimum or low level of temperature/humidity and at the maximum or high level.Even more than that, the fan has many different speed/strength settings, and you can set it so that (for example) if the humidity is very far past your chosen thresholds, the fan not only turns on, but also increases its speed depending on the percentage of difference: large difference = fan speed set right to your highest setting and small difference = increases fan speed incrementally/gradually starting from your lowest setting.If you connect the controller to your wifi network (the controller has wifi capabilities), you’ll find that in the “advanced” section of the controller’s app, you are able to also set up alert notifications based on different triggers you can create; thereby notifying you instantly even when you're away from your house. It also has awesome graphs with detailed time data.I’m very impressed with this product, and highly recommend it.

This fan is incredible. I don't know what I was expecting, but I feel like I didn't expect enough. The set up installation was easy, the controls are intuitive, and it's actually pretty quiet. I am very impressed with this fan and have thoroughly enjoyed having it.

This was very easy to install. Just cut the right size hole and insert. I'm using it as an attic fan to help cool the house without turning on the AC. It works great!
