HG Power 6 Inch Exhaust Fan with Speed Controller, 308CFM Wall Exhaust Fanfor Kitchen, Bathroom, Metal Extractor Fan for Pet Room, Smoking Room, Attic, Garage, Window Ventilation

The fan had very good air flow. It was quiet in the low fan speed setting and just more louder in the highest speed. It has a solid build.

Pulls a ton of air on the higher speeds, and it still effective but much quieter at the lowest speeds. If you don't specifically need the backdraft plates that are flapping about on the back, removing them makes this run much quieter. I found it emitted a hollow kind of resonant sound with them in place which drove me crazy. They're easy to remove.

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.

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.

Absolutely solid fan. Sucks in the air around it and the correct size for what im using it for (3d printer VOC ventilation).

We got this for a bathroom that did not have an exhaust fan. We fitted a thick piece of plexiglass in a window and cut to fit. I love that it can be turned down when full blast is not needed. This will be louder than a typical bathroom exhaust, but it can move some air when you need it. It seems to be made well. We have had it installed for maybe a few months now. We are very happy with this purchase so far.

This was a loud piece of crap. Died after 30 days. do not purchase

Too much noise

Muy buen equipo, excelente calidad

The 6 Inch Exhaust Fan was very easy to install, which I appreciated. Unfortunately, that’s where the positives end. The fan itself doesn’t look very nice once mounted, and it’s much louder than I expected. The noise makes it unpleasant to use

The fan work well it pulled most of the cigarettes and cigar smoke.The noise level is not to loud but noticeable it’s only a week but will see how long it lasts.

Fonctionne parfaitement et belle allure autant pour la salle de bain que la cuisine. Je la conseille fortement à qui en a besoin pour le chalet car ça ne prend pas beaucoup d’espace. Elle a plusieurs degrés de vitesse et c’est un bon point car on peut la laisser fonctionner longtemps sans être dérangé par un bruit de fond agaçant.

Installed (2) 6" fans in the back wall of my shop. We're easy to install and look clean from the inside. The open back with back draft is not a proper exterior fnish tho. Definitely needs some sort of vent or finish cap. Wish I included this, but I guess it's not necessarily part of the exhaust fan... Now to the important stuff. I honestly expected more power. They are kinda low and slow and don't overly move a crazy amount of air. My rooftop vent fan in my rv seems to pull more.. not really a fair comparison tho, 250 dollar fan and these are 1/5 the price. So you get what you pay for. They work, look nice, but arnt "excellent"
