HG Power 6 Inch Exhaust Fan, 308CFM Wall Exhaust Fan for Kitchen, Metal Extractor Fan for Attic, Garage, Window Ventilation, HVAC System

I got this to get some ventilation in the chicken coop. It's ~15square foot. The 6inch exhaust fan does a nice job. It pushes hot air out easily. No problem with the install. We put it on the wall up close to the roof where the hot air lingers. The hardest part was cutting out the circle in the wall. Very much worth the cost. I was worried it would be loud. On low is very quite. On high to my surprise wasnt as loud as I thought it would be. The chickens love the upgrade as well.

Why did you pick this product vs others?:Priced right and functions well. Fairly quiet while moving a lot of air. The cord length was more than adequate and the rocker switch make control easy.

As others have noted this is a heavy duty quality built 6" fan. It moves a lot of air (300 cfm not sure, that's a lot of air. I have equipment to measure the flow just haven’t done it. One of these days...)The noise level comes from the air, not the motor. You can't move that much air through a small fan quietly. Its very quiet at minimum speed which still moves quite a bit of air. Guessing slightly less than half speed.Some fans on a speed control whine at reduced speed, no trace of that here. I dropped it a notch because the speed controller is mounted near the plug instead of near the fan, inconvenient. It also operates backwards, starting at maximum instead of minimum speed as others I have do (have several AC Infinity fans also high quality). Not logical either and usually want minimum speed so have to turn quite a bit. Minor but...On value for the price I give it a 5. It's worth the money, but advise buying the one with the speed control unless you need the full airflow all the time, and noise is not an issue.

Quiet and effective. Good price for the quality.

I wasn't expecting much when ordering this fan, just a small exhaust fan to keep temperatures down in my attic and elsewhere. I ordered two, and the quality of both is amazing. All metal construction, even the blades. The whole fan feels heavy, constructed well, and worthy of the name "industrial fan" they put on the front of the owner's manual. It's also very well balanced and doesn't rattle or shake, despite the high speed. This is not a quiet fan that you want in your living room or something, it moves a lot of air, which is going to make some noise. Another big plus is the cord which is extra long, with a nice switch. I'm very happy with this purchase.

I buy a lot of industrial equipment for work. This is a really high quality product. If you need an in-wall fan that moves a lot of air, this is a great option!I bought this to move air in between rooms in my house. We have a mini-split in the main room and our bedroom doesn't get any of the heat or air conditioning.This fan works perfectly to get the conditioned air into our bedroom. It's a 130 sqft room and with the fan running at half speed, it equalizes the temperature in the two rooms.I put a fan speed controller switch on it and wired that into the wall of the room. At full speed, it's a bit loud. We run it at half speed normally and it does fine. If we need to cool things off quickly, we can do full speed.The only bad thing about it is the power cord. This is obviously an item that needs to be wired in. It's a weird choice to put a plug on it. I rewired it so it would have a contiguous wire all the way to a junction box. Not a big deal.This is a seriously high quality product. The metal is very thick. The fan blades are metal, not plastic. The fan blades are also balanced from the factory. This is an expensive process that helps the fan run more quietly and greatly extends its life. I didn't expect it to be this nice.If you need an in-wall fan that moves a lot of air, buy this!

Strong fan but loud. I will keep it and see how I can minimize the fan vibration

I bought this to use as an exhaust fan for my laser engraver. It works well installed through the wall as shown. I like the plug in cord with a switch built in, no wiring required, just plug it in and turn it on to use. The price is good, in fact the 6" holesaw that I bought to cut the hole in my office wall costs more than the fan. I wish it came with a cover for the outlet but at this price I won't complain about that. You'll have to purchase of fabricate a cover for that end.
