    Review by on Jul 10, 2015

    Seems to be a good quality unit, time will tell. I cut the hole in my shed according to the specs. on the website which was 20.5x20.5. The fan was 20x20. Other than the diff. in size I am happy.

    Good Quality

    Review by on Jul 12, 2013

    Haven't install as of yet, but the quality appears to be very good. No plastic part, that's great. One louver was slightly bent in shipment, but still operates just fine.

    Excellent exhaust fan

    Review by on Sep 13, 2012

    Better than expected. It does make some noise moving the air (fan blades), but is perfect for what I wanted it for. I mounted it in the side of my metal shed so that it draws air across my 16,000 watt generator when it is running. Keeps the generator cool, and sucks the heat from my shed. I didn't even build a wooden frame for it and just screwed it to the metal wall after cutting a 20 inch square with my multi-tool.

    Great Product

    Review by on Jul 28, 2012

    I researched several exhaust fans and some with variable speeds that were more expense. When it came to making my choice, it was the 20" DURAFAN® Select Speed Shutter Fan. The installation was really easy (did not have to hire an electrician-big savings $$$). I needed it to cool and circulate the air more in the miniature horse stalls, where I already had two separate box fans. All we had to do was remove the grate bars in the tack room and install it right in that window with a small filler piece of wood and sealed around the insert. It doesn't shake or make anymore noise than a normal fan. I use it in #2 speed and it is great in the 20X20 area.

    The *only* thing I found wrong was the factory had put the fan on upside down to the shutters! So a big "oops" on their quality control dept. Just because I'm blond I'm not stupid - shutters always fold downward on exhaust fans and when you pull a chain for the speed - the chain hangs downward! It wasn't any big deal to unscrew it and turn it around, otherwise I would have given this product 110% of satisfaction. It is a great exhaust fan for the money.

    love the fan

    Review by on Jul 26, 2012

    Not sure what the other people were complaining about, i think the fan is excellent and not noisy at all. I give QC Supply an A+!!!

    Great fan

    Review by on Feb 5, 2012

    The fan arrived on time and in perfect condition. Installation was easy. I have a 30 X 40 shop with 16 foot high walls. On the middle speed I can feel the fan pulling air through an open man door on the other side of the shop and watch smoke being pulled from the room. Other reviewers have commented about the noise however I found it to be much quieter then my industrial ceiling fan. I think it’s a great buy.

    Efficient, but noisy...

    Review by on Nov 2, 2011

    Arrived in intact condition, very minimal packaging. Installation was a snap,take it out of the box,place in opening, fasten to opening supports,plug it in & pull on the chain. Presto. Fast and easy. Only drawback is that this fan is loud on the low setting, louder on medium & loudest on the high setting. Excellent air extraction though. So, overall a good deal for the price

    Best price I found

    Review by on Jun 16, 2011

    Just installed in a 30x40 with 12' walls, does help to move air through, a larger fan might have been better. The 3 speed switch is a great option.

    Good product

    Review by on May 13, 2011

    Put this in a 16 X 24 shop with a 12 foot ceiling. I got the 20X20 fan and it moves plenty of air on low speed - creates a noticeable draft by drawing air through the windows. Like Bob said, it's a bit out of balance at high speed, but low speed works so well I can't even imagine needing high speed. I'll try Bob's solution and see if it works. Overall I'd recommend this fan, especially as many others are much more expensive.

  • 4 Stars

    Excellent product at a good price

    Review by on Apr 14, 2011

    I'll be using the fan in my newly constructed cook house to remove the smoke from the barbeque pit and to circulate air in the summer.

  • 4 Stars

    they work great I would buy them again

    Review by on Apr 11, 2011

    I put 2 of these in my green house to help keep it cool in the spring/ fall months. I only use the low setting, they are plugged into a thermostat controlled curciut

    *one of the fans was unbalanced and shook on high speed, it was an easy fix. 1 of it's blades was slightly bent and there was no damage to the box it was shipped in.
