I bought this fan for cooling my dorm room in winter. I would normally just open my window in winter to let cold air in but i have several plants I keep near the window in question and have learned that the cold air absolutely will kill them. So my room gets hot and stuffy if my door was closed. Having many roommates I can either have a cool loud room or a hot quiet one. But here's the brain wave, in summer I have a portable ac unit with one of those 6" hoses that goes to the window. In winter I like to put in the basement cause it's large and can't be used to suck outside air in it only exhausts, what if I left the hose? Now i can direct the cold air and it's no where near my plants! Great! Expect that actually not that much cold air just comes in. This is where that fans comes into play, it happens to fit perfectly on the hose and sucks fresh cold air. When coupled with their speed controller and a thermostat plug I have a little climate control system that can be easily adjusted to the current need. I made a little mount out of some plywood to hold it in place and it's great. The design lets me flip the fan around so that I can either suck air in out push it out, this is great if you wanna get an unwanted smell out... maybe your college mates life ending flatulence... or whatever. When I was making I was a dumb hence the head line, I plugged it in and held it against the hose to try and see how much air would pull through and didn't put the guards on. This was dumb... the fan blades caught a tab and nearly took my finger off, instead one of the blades broke off and went falling across the room, totally user error there, since I had nothing left to loose because you can't use it with a broken blade as it's off balance and vibrates so aggressively small furniture moves around, I decided to try just gluing the blade back on with IPS 16 and acrylic glue... Amazingly! this has worked fine though i still sometimes cower in fear of it shoot that blade into my tv. Moral of the story just put the guards on it Anyway about the fan +pretty quiet, I heard quieter but definitely get the speed controller to really hush it up, probably quieter than most range hood +moves a lot of air going all out with good static pressure, I can feel it come under the door +very well built, outside ring thiccc aluminum +price is very good compared to other inline duct blowers, even is that's not what it's supposed to be +is constantly exposed to freezing temperatures and works just fine, I mean it's an electric motor... -the mounting hole pattern is a little weird, but its a weird size and shouldn't matter -I don't really like the way the detachable power cable connects, kind of some small pins that angle out at a 45 instead of tucking against the frame neatly, the connector doesn't really feel like its seats all the way down, without felling like you're going to break or bend the pins, but you should really only do that once, and will not come off, so really just a nit pick -speed control is separate aka spend more money... but being able to mix and match in their line up of products is very nice as you don't have to buy a more expensive one with it built in Good fan great for venting will run probably a long time don't be dumb like me get the speed controller, unless you have it far away in a green house or something? oh have had it for like 3 months or something

Great little fan that kicks out a surprising amount of airflow. The variable speed setting works perfectly — I mostly use it in my grow room when I need to push air in a certain direction, and it’s easy to move around wherever I need it. Solid build, reliable, and does exactly what it’s supposed to do. Highly recommended if you need a compact fan with real power.

EDIT: May 1, 2021– still running strong as new 24/7. This is a great example of value in getting what you pay for! It’s working as planned, too….I find I have to remind myself to clean the litter rather than nose-knowing every single time the mouthy little furbeast does a deed. I bought two of these for a slightly unusual purpose: forced airflow through carbon air filters built into a cat litter enclosure. The enclosure (also sourced from Amazon) cabinet already had two vents with brackets to hold activated carbon air filters, but with a large opening to facilitate a large beast ironically (whether by intelligent or evolutionary design) equipped with razor-feet there was no way to keep the smell of his “business” from wafting back out. Enter the muffin fan! Admittedly, with one of these mounted over each of the two vents (and an ionizer on the “bathroom” setting), the walk-in closet in my office/guest bedroom does sound like I’m hosting a server farm....but I tell ya there’s a forced airflow through those carbon filters now! Better yet, my entirely-too-sensitive olfactory response is all the better for it. These fans are very powerful. They’re running 24/7/365 since purchase and no problems. Given they’re in my office, a quieter function would be optimal, but quieter would also impact effectiveness in this particular/unorthodox application. They’re also exactly the right size to fit over the filter frame, which is how I found them. I’m in the technical field and am familiar with the noise level generated by this type of fan, so I knew what I was getting into...if you need a small but very powerful fan for a forced airflow environment, this is what you’re looking for! Just don’t be surprised that this kind of power isn’t whisper quiet.

Just plug in and use. Bought as a replacement fan for the kids air hockey table. I didnt think its loud as other reviews have said, but the fan we had before was louder so, in comparison this isnt loud, especially when kids are playing and its mounted under table.

Very satisfied with this purchase. These fans are everything I hoped they would be. These fans replaced our loud rattle fans out of our 1970's heatilator fireplace. The original fans were loud and probably put out 75 cfm. The new fans are overkill and are too loud at high speed. That's the point. I wanted an oversize fan to superheat our living room, and with a speed control turn them down to 50%. That's the only way These fans will work for a heatilator blower. They need to be adjustable. Regardless, we're now cranking out 400 cfm with 2 fans combined and I couldn't be happier. If you're looking to upgrade your old tired fans, highly recommend these. Oh, I forgot the quality is top notch on these fans, with a metal housing and ball bearings, they do not vibrate. The rotary speed control is a Vari-Speed 6 amps. Enjoy!.

Great material and finishing. It came with protection grid and screws for mounting. It has been running non-stop since installed a few months ago in a commercial bottle cooler. No appreciable noise, good airflow.

It perfectly fits without any excess space in the inside of my 185mm outside diameter vent. It's a little loud, but moves a lot of air. The only downside, is the kit had only two screws and three nuts. The fan has four holes. It cannot be solidly mounted IMO using only two screws. Put in four screws and nuts, and save us a trip to the hardware store, please. It's connected to a thermostat set at about 83 degrees, to ventilate a small outbuilding, and has been running daily. Follow up: AC Infinity reached out to me, and sent a package of screws, even after I explained that I had obtained some from hardware store. Great customer service.

I own this - just purchased it and it is no where near that loud as that guy whose video of his fan sitting on a hard floor in the middle of an empty room sounds. That hard floor it is sitting on doesn't help plus it sounds like the noise is echoing inside a relative empty room. My fan is now sitting inside the window frame of a small bathroom single hung window. To get it to reach to the window screen as it sat down too low inside, I put a piece of wood cut to size under it and then added an old thick rubbery mouse pad on top of the wood and then sat the fan on it so it now sits up level to the window screen. I used rubber washers on both sides of the screws also to stop/deaden sound. I face it so it exhausts air out of the bathroom window and I left the bathroom door wide open to the hallway. Centered the fan so it was facing the open front door while sitting inside the window frame. When I came back in an house, I could feel the hallway was cooler / less humid not just the bathroom. I WISH I could buy the 10" tall fan but my bathroom window only opens to 8" and the larger fan won't work. What I like about this fan is that the rest of the window screen is open so fresh air can come inside even while this fan is pulling old air out. This sits nicely inside my small on my kitchen window sill. My unit is not as loud as the one someone posted a video of. I added my own washers which are rubber and I set the unit on an old rubbery mouse pad that was cut to fit. That helped deaden vibration/noise. Now I have room for a fan AND my plant on the same sill. I have a Honeywell fan that has 2 fans (exhausts or not - you choose) but it is too big and it noisy (as noisy as this little fan). But with this fan I can have my plant. I gave it 3 stars because whoever packed this 11" fan gave me 2 screws which are way excessively long almost as long as the whole fan itself. Those 2 screws stick out one side like 2 long spears. Ridiculous. I cannot put the fan up next to the window screen because those LONG LONG LONG LONG very thin 2 screws will poke a hole in my window screens. I would rather avoid a Home Depot trip due to Covid-19 and my health concerns.
