SAILFLO 11.6 x 11.6 Inch Cutout Window Shutter Exhaust Fan with Reversible Airflow, 476CFM 35W Wall-Mounted Quiet Ventilation Air Intake Extractor for Bathroom Home

Attic bedroom REALLY needed an exhaust fan! While we've used a window model to pull heat out during the day, the bring cool air in at night, only one window was installed high enough to pull the heat accumulated at the ceiling. We didn't build the house but I sure would have done it differently if we had.I read the reviews and the mfr instructions that this fan is ONLY for *wall installation*! but we already had a hole in the ceiling where the stovepipe (from the wood stove downstairs - that we removed) went, so I thought "what's the worst that can happen if we put it in the ceiling?"It's an absolutely perfect fit! We removed the "metal frame" for the stovepipe, cut the hole about a half inch larger on one side for the 10" fan, screwed the fan mounting into the wood framing like it was made for this fan.The ceiling placement is near the light switch w/ an electrical outlet BUT the fan's electrical cord would be perfect IF IT WAS 12 INCHES LONGER! As it is, I had to mount an extension cord to the wall.We only use the "exhaust" function to suck the heat accumulated at the ceiling outside - I can only imagine the "creepy crawly" things the fan would bring in... The shutters work perfectly (after clearing away insulation that could obstruct opening and closing). We've had it running practically 24/7 since installing it and it's kept the bedroom 10° to 15° cooler!Personally, I like the "white noise" of the fan, so I can't complain about it. On the other hand - since the fan is close to the TV, and husband watches TV upstairs, he has to turn up the volume 🤷‍♀️ meh, it's fine.So, turns out you can indeed mount it in the ceiling without terrible repercussions! Great fan for the price, easy to install, and works well.I gave it 5 stars but would dock it half a star for the short electrical cord - c'mon guys, would another foot kill you?

This little champion has been running non-stop now for 2 years and still running like a beaut! Put it on the window sill for one of the outer bathrooms and never gets turned off just ventilating all day. No problems at all. And even running it all day everyday it still doesn’t use much electricity. If thats not the GOAT of fans I dont know what is. Cleaning it is too easy as all the panels slot out. Rain hail or shine this beast chugs along. Highly highly highly recommend. I’ll update this in another 10 years when I’ll write that its still going strong.

Update: I FIXED IT!!! One thing I don't like about American fan companies is that you can't easily (if at all) take a modern appliance apart, clean it, and fix it, like you could in the "old" days. This little fan can be taken apart and cleaned - with a little logical thinking. I also opened the electrical switch section to check the wire connections: All good: no sign of a short or corrosion. But when I opened the on/off switch section - I found just a little bit of grime - and that little bit got in the way of the connections, stopping the fan from turning on. With a little rubbing alcohol and a small cotton swab, cleaned it up, put it all back together, and now the fan runs like new again. Yippee! How's that for a girl who has never done this before? So, if I can do it ...Dear Manufacturer: How about a Youtube video to show people how to do this? :) (And maybe a six foot cord on future models.)Original: When I first received this fan a little over 1 year ago, it was finicky for unknown reason. Somehow, got it working and it's been working fine for some time. Then it stopped. It's not being finicky this time, it just stopped. The switch works and I can cycle through the three settings: exhaust, intake, off-and-close-shutters. But it the fan won't come on, at all. I thought maybe it couldn't handle the cold, so brought it inside to test it at room temperature, but it still won't start. Would appreciate it if company would contact me for troubleshooting steps. Thank you.

This 8” fan fit perfectly in my glass block window. Works well. For reference, my glass blocks are about 7-5/8” square.

This little fan was great while it lasted...it provided strong airflow in both directions. But...after only 7 months, it just stopped working. This is not a cheap fan....it should last longer than that. And oddly enough, I find no info about a warranty. Go figure.Beside the fact that it stopped working, one other major complaint: I built a wooden frame around it, so I could take it in and out of the window as needed, just like an actual window fan. Since there is no switch on the face of the fan, you have to use the pull cord which is at the bottom of the unit. Unless you build a frame and leave quite a few inches at the bottom for you to be able to access the cord, then you simply can't get to it because the window sill is in the way. So...if you build a frame to use it in a window as I did, leave a good 5-6 inch gap under the unit so you can actually turn it on and off.
