AC Infinity, AIRLIFT S12 Shutter Fan 12”, with Speed Controller

Very impressive exhaust fan. Speed is adjustable and surprisingly powerful. I'm using it on a wall behind my bench grinders to expel dust created by the grinders. Works perfectly for my application.

We bought a 10x12 shed for our backyard earlier this year. I plan on storing electronics (inventory) for my business in it so I wanted to keep it as cool as possible during the summer months. My favorite feature is the memory function. When the fan is unplugged and then plugged back in, it "remembers" the speed setting. I combined this with a smart outlet and an Amazon Echo device with a temperature sensor and created an Alexa routine so when the shed temp exceeds 85° F, the outlet is powered on and the fan resumes the same speed it was before being powered off. When the temp drops to below 85°, the fan power is cut off and the fan stops. I had to reframe the vent hole, but it works awesome and is SUPER QUIET. I could have spent more for the thermostatically controlled unit, but I already had a spare Echo and smart plugs laying around so I opted for the less expensive unit. I'd buy one again in a heartbeat should I ever need another exhaust fan.

Easy to install, quiet, however I would like to know if the length of the controller can be extended somehow?

I bought these to replace conventional 1800 RPM exhaust fans. I run them at half speed and they are very quiet. I disassembled the unit, mounting the motor, fan, and cage into the existing wall-mounted louvers. The fan cage bolted into the same fasteners as the old fan, so installation was a breeze. I did not use the louvers, but they looked to be good quality. I like the fact that the speed control remembers what speed is programmed if power is removed. I have the fan controlled by a wall switch, and treat the speed control as set-and-forget.

Was very easy to install into existing air vent in the garage. Works perfectly with a separate controller purchased and helps cool the garage in Arizona from 102 down to 93 during the daytime.

Install was easy, Fan seems well made, quiet… not strong though. I bought a 12” to send welding fumes out of a 20x12 shop and didn’t notice much a difference. Recommend the 16”+ for anything bigger than a small room

I set this up in a movable frame and furnace filter to pull paint & finish fumes from my small shop (600 sq. ft.). Judging by the amount of paint color on the filter it works well running at 3/4 speed. I do spray relatively close to the filter (6 ft.) I plan on installing a second fan to increase the air flow. The switch cord has enough length to install in a convenient location. The unit is well packaged with good instructions. Determine cfm needs to select the correct fan size. This was a good buying experience….

I installed the fan on my Palram greenhouse,it works really well sucking hot air out and circulating air, quality built and well packaged, everything needed and then some for install, even my idiot husband could figure it out :)
