14 In. Heavy Duty Exhaust Fan with Automatic Shutter

I stumbled around on others reviews of this product after i had already purchased it. I was... nervous. I got cold feet in a way. Sat there starring at the horrifying words on my screen for a great while. Almost cancelled my entire order. Then i Waited Till it came, figuring i could return it if it was an issue. It was intense to say the least. The product got here. I opened it. AND THANK GOD!!!!!! I didn't cancel. I was amazed at how well it works and how easy it was to set up. Even with a humidity and temp Thermostat. I heard things about it not being built "heavy duty" enough for some people. I'd have to disagree. But i did no such man handling with my installation process. It work's better then i could have ever thought. I got my money worth, and i know you will. BTW 14oo cfm was enough for my 28 foot Length by 11 foot wide space. You can use that for what it's worth when deciding if you should get the 3000 Cfm. Moral of the whole thing. They say people don't review enough and that it cause feedback issues. and this is a problem. But i say, If your going to do a review of an item. Do it with truth and integrity. cause an item like this needs better reviews.

All in all, it is a great fan and made in the US. It does make a clicking noise at full or near full speed and I believe it is the shutters, I have to look into it still. I do wish I had sprung for the next size up, but that was purely my decision. The noise it makes other than the clicking sound, which I feel I can fix, is no really that loud for a fan of this size that moves 1400 CFM. Most large plastic house fans are 20-21" which is twice as big. Fans should be measured by the sq, inches or ft that the inlet/outlet measures. A 20" fan has twice the surface area as a 14" fan which, mostly, is why the 18" model can move over twice the CFM of air yet is only 1.3 times as big across. The fan is also not intended or designed for in-home use. Its design is that of something like an attic exhaust fan which would be sound-insulated by a ceiling and insulation. The blades of a house fan are smaller, smoother, and pointed as opposed to square. House fans cannot create as much suction or pressure, depending on how you look at it as a fan designed like this, which is why it has a tube. It also has only 4 blades, probably because they will stay balanced longer, can be cleaned more easily, and are less expensive to manufacture than a fan with more blades allowing for more of the cost to be put into the motor which would imagine has far longer-lasting bearings and superior efficiency per watt/hour of electricity used. Lastly, some of the reviews mentioned a cover for winter and a screen. No real need for a cover if used as designed and a screen would only reduce efficiency. anything small enough to fit through it grate would just be blown out most likely anyway. So that is how I see this fan. By the looks of it and the sound of the motor, it should last quite a long time even if used all day every day, or near to it. My only real issue is the shutter noise, which is not all that loud and intermittent. I would suggest buying some inexpensive quilted material and cutting a circle out (approx. 30" should do nicely)and just placing it over the end of the fan and using a strap that can be tightened around the tube to hold it on for a winter cover. Screening is cheap.

All good but cord is very short and inconsistent exit point. I bought 3 fans. One fan cord exits the bottom then other two exit the left side. All cords require the source electrical box to be immediately next to the frame of the fan.

Installed two of these for my small glass studio and they work perfectly. Super simple to set up and wire in the plug head. They move way more air than I expected which is nice, I can see why a speed controller might be necessary. Vents move nice and freely, and didn't have much of a problem with them freezing shut during winter. Only complaint is that they are VERY loud, definitely have to raise your voice if you're talking near them.

The fan operates as expected, but there is no built in screen or mesh to keep out critters, particularly when the louvers don't close all the way (if at all). The louver hinge mechanism is very poorly designed. The operation is unreliable due to the easy bending of the flimsy sheet metal (the sheet metal of the louvers is, by design, very thin, so they will open automatically). They don't generally open enough and if they do, they don't usually close. I will probably remove the louvers and fab my own. The housing of the fan is fine (not flimsy, as some have suggested). Given the number of changes I will need to make to get this fan to work for me, it would have been cheaper (and just as easy), to just buy a less expensive window fan of the same size and capacity, gut it and rework it to my application.

Fan works fine, no issues with shutters, vibration or noise. Easy install in attic with 25' of duct connected to a ceiling intake register. Almost undetectable as far as noise, although i suggest rubber isolation pads to deter vibration. Installed with Alexa enabled switch and set schedule to come on a couple times a day for 4 hours total. This helps keep the upstairs temp reasonable, although next time I'd go bigger, maybe 20" or even 24" on 1800 SF house. So what does that mean? In my case, AC power went from 916KWH per month to 384KWH by using this fan, which consumes about 18KWH per month. At .13 per KWH, AC cost went from about $120 to $50 per month, 58% decrease including power for the fan. Return on investment is outstanding, in my situation the entire system cost about $400, so it all paid for itself in one summer.

Solid product and moves lots of hot air. Enclosed shroud sets it apart from other fans. Reasonably quiet operation. Used with a 70deg thermostat

so far no problems. installed in a barn for better circulations. cheap compare to retail store. but is not anything fancy . just a fan. I still feel like it could it could be price even better.

Very loud, much more so than I thought. Comes with very small wires but still hooked up mine to 12gauge wiring just in case. Wish it had an adjustable amount of air flow but didnt pay extra for that option!

The screws are too long and the blades kept cutting into them making really loud noises. Also there wasn’t any mechanism to absorb the vibration causing the screws to loosen. My husband had to reinstall 3 times and finally macguyver something to make it fit.
