AC Infinity, AIRLIFT S16 Shutter Fan 16”, with Speed Controller

I used a pair of these as a whole house fan, putting them in upstairs windows. I especially like the speed control, which allows you to run the fans quietly, albeit at reduced air volume. They also appear to run on lower power than the other whole house fans I've used, and it is nice that they have standard wall plugs, so no need to wire them up to an electrical box. At high speed, they are noisy, but no worse than other fans that move significant amount of air. One fan does not move enough air to adequately vent our 2000 sq ft. home. Power drain for the different speed settings is as follows (per fan). From low to high speed, all in watts: 6, 9, 14, 21, 29, 40, 55, 86. So even at top speed, these are only drawing 86 watts. The fans are also well made.

I needed an exhaust fan for a 1,320 sq ft post and frame pole barn I had built to store by dieselpusher RV and Jeep. The rafters were 14-foot high with a metal roof, so there was a lot of space that needed ventilated during hot summer days. This exhaust fan is built like a tank! It has a powerful suction and easy to use controls with variable speed selection. It integrated well with a separate thermostat I bought (but by the built-in thermostate version - it is worth it). The long cord on the controller allows me to change speeds and turn the fan on/off while standing on the barn floor. I highly recommend this exhaust fan unit!

So far (one month) I love this fan. I got it to replace a failing Lasko 16" window fan after determining that current version is not as good as the ten-year-old one I had, so I went looking and ended up with this one. It works great and at setting 4 (out of 8) has more suction than its predecessor. I am thrilled to have a fan with louvers for the first time, which work great. I look forward to some bad weather to assess how well it performs at avoiding water infiltration (when off of course). The only thing I don't like is it is definitely noisier than the Lasko it replaced, even on lower settings - on higher settings it is *very* loud. I was surprised because it has more blades than the Lasko (3) - usually more blades means quieter. This may or may not matter, depending on your use case. Most of the noise appears to come from the louvers and their joints, not the motor. In my case I'm happy to trade noise for suction and hopefully lower energy consumption. I measured wattage consumption and it ranges from 25 watts on lowest setting to about 375 watts on highest. I neglected to measure the Lasko for comparison. Now, I pray it lasts for a decent time. As it involves electronics, I have it plugged in to a surge protector, which I highly recommend even though not mentioned in the instructions. I've posted a picture of its mounting in a window in my NYC apartment. UPDATE 7/31/21: I continue to love this fan. It's been running almost continuously now for 2.5 months. The initial noisiness of the louvres seems to have worked itself out - now on the lower settings the air sounds predominate. On higher settings (4 to 8) it is still rather loud. But it works so well on lower settings that I don't need to go there - generally "2" is sufficient to get quite a suction from all the windows of my multi-room apartment. Probably obvious, but in case not - this is *not* a consumer-grade window fan. I was able to adapt it to work as one because I am quite handy and have plenty of wood and plexiglass around. It's really designed to be fastened into a wall opening. In a window, great care must be taken to seal the window opening outside the fan housing - if you don't, the suction and efficiency will be severely compromised. UPDATE 6/16/22: Continuing to love it ! UPDATE 12/10/23: Still going strong. UPDATE: 7/27/25: Still going strong.

Purchased 2 and worked great.

This is a great fan! It is very powerful. Well-built and a quality product. Has a great control and lots of cord. The down side would be that it is very loud. The motor runs off a pulse width. This makes it very powerful and efficient for the air it moves well.. But this pulse signal can be heard through our entire home. For some it will not be a issue, it is turbine in sound and may very well put some to sleep. Others might not feel that way! It is a fantastic product for the price, just use caution with how you place it in your home for noise..

This louvered fan was great for my basement. We keep our litter box down there and noticed the smell was way down as well as circulating air from the main floor to the basement. extremely quiet and the fan motor is very strong. The fan speed is very adjustable with the controller it came with. I would recommend this product.

I purchased the smaller version of this fan to ventilate a generator enclosure, it did not move enough air so I purchased this model and after running the generator for four hours with the outdoor temp at 78 degrees the temperature never exceeded 96 degrees inside the enclosure with the fan running at full speed , I think that when running with the outdoor temp being cooler I could reduce the fan speed. I’m very pleased my generator runs cool and the generator noise is greatly reduced

this is the first time I have purchased an AC Infinity product, and I for sure would buy one again. I didn't think about when I purchased this and wish I would have gotten the smaller one for install but this fan works fantastic. I use this fan to ventilate my glassblowing studio and after doing a smoke test, this thing for sure is pulling a lot of CFMS. In my 10x35 room, it is places in the window in the center and it's pulling more than enough to get the fumes out. I would buy this again if it ever dies on me.
