AC Infinity AIRLIFT S12, Shutter Exhaust Fan 12” with 10-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.

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.

I had to take the black air fins off and use a set from 40 year old exhaust fan because these things stay half way open when the fan turns off. Fan works well otherwise after one month of use.

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.

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.

I bought this for my bbq trailer and it sucks the smoke right out and isn’t very loud at all! Fairly easy install and good quality!

I use this in an 8X8 chicken coop for ventilation and runs 24/7/365. No complaints, really quiet and like the 6/7 speed choices

I bought 2 of these for my basement cause I was looking to exhaust my cigar smoke and sure enough it works like a charm. Placement makes a big difference too so no complaints here.
