6 Inch Inline Duct Fan 240 CFM, HVAC Exhaust Ventilation Fan with Low Noise for Basements, Bathrooms, Kitchens and Attics, Silver

Used this for brining in fresh air for my sim racing room. Works great. Also can flip it to pull hot air out with air conditioner. The variable fan speed is great. Have the control box mounted to my racing rig. It is a little loud but it’s not ment for what I’m using so it has a nice background noise.

Sorta loud but definitely does its job. Using it to vent a resin 3d printer and all fumes are gone now by using this. Surprisingly light weight and low power draw too

the fan moves a lot of air, and the speed control is reasonably linear allowing for smooth speed adjustments thought-out its range without any spots that seem to not make much difference. it doesn't come with any means of attaching or hanging it at all, no strap, nothing!!! i grow veggies in the tent rather than weed like most here so i have no need for a carbon filter and a strap or mounting bracket would of been a nice addition. it's reasonably light weight so i installed it into one of the vent openings of a grow tent and just used the synch cords to secure it, it works well. i have it just to help with heat removal in the top of the tent when the lights are on, i keep the lower vents of the tent open all the time so there's a bit of natural thermal lift, but on hot days i had a little more temp climb than i liked. i have noticed that the room i have the tent in gets a good bit warmer with the tent venting into it so i have a 16ft 6" hose and it fit the fan perfectly, and i'll get a window vent to vent the heat outdoors. other than it being a bit noisy, it's a great addition to the grow tent.

Using this blower to move air through residential duct work to farthest room from HVAC. It has lasted for 3 years running 24/7 and makes that room temperature consistent with rest of the home. It is fairly quiet, but can still hear when running it (sounds like low level of white noise). Combined this with a pressure sensor at end of the main return trunk from HVAC and works like a charm. Strong buy recommendation!

Moves a ton of air and at 50% its very quiet. I use mine as a circulation fan, when companies want to charge $50 for a dinky little clip fan that moves 20-45 cfm, get this instead. Worth every penny

Runs ok, moves a decent amount of air, seems to be well constructed. However, i am measuring 65 dba on the outlet side at 6 inches and 78 dba on the inlet side at 6 inches, well above the claimed 37decibels. I am using this in a dog kennel and bought it because of the low noise rating. probably will be returning this fan.

This fan was used to make a homemade air conditioner with a ice box cooler. It is very powerful and serves a great purpose. It is not very loud so that's a plus

I use this for my laser engraving enclosure to pull the smoke outside, and it does work great. Strong and quiet. Easy assemble

Sehr gute Qualität gegen Preis. Nicht so laut und ziemlich stark Luft. Für kleine Räume oder Zelt genug.

Super quiet, easy to set up. Really makes the exhaust system flow like it should. Invaluable for any indoor garden set up.

Qualidade em tudo.

Using to move air from an overly hot room in my basement into a colder laundry room. It moves the air well with not a lot of noise. Most of the noise is from the air rushing out. The 6" flexible vent hose fit well and was simple to install. There is not switch, just a direct power cable and plug. I use a smart switch to control it based on the weather. I used the suggestions in another review to reduce any noise: I hung the fan and hose from bungee cords. I put 2 small hooks in the ceiling on either side and looped a cord between them along the length of the run. The pipe and fan sits inside these 'cradles'. It is in the basement below my bedroom (no insulation between) and I can barely hear it. The laundry room is toasty warm now.
