VIVOSUN 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!

This was great for a basement project that needed ventilation. Was able to repurpose my dryer exit with an extended hose. Nice and quiet, yet moved good air.

Installed in-line on a 6-inch HVAC duct to increase airflow to the second floor due to too cold in winter/too hot in summer issues. Pros: super easy to install- 45 minutes or less if you’re handy- longer if in a tight or confined space. Very inexpensive fix if you have an upstairs that is too hot/too cold due to poor HVAC volume on upper floors. Cons: it’s really very noisy. If you’re ducting it to a bedroom, use a quieter model with a plastic body- all the sound carries through the ducts. If you plan to install yourself, buy yourself BOTH left AND right handed tin-snips to cut out the duct work you plan to install it in. Note you can also cut into ductwork with a utility knife, though only recommended for initial cut. Connect the ends with flashing tape to make things easy. I bought the Vivosun black plastic model with red fan blade to duct to all the upstairs bedrooms (4) and now it’s like an icebox up there in the summer. Running our central air no more than before we’ve managed lower the upstairs temperatures by 10 degrees easily- making it so much easier to sleep. I was originally going to upgrade the central air, but that was a multi thousand dollar change – this was in much better solution. Note- install these as close to the blower as possible- ideally right off the trunk line. Also HIGHLY RECOMMENDED- buy and connect to smart plugs that you can control via app or google home/Alexa. That will allow you to easily turn on and off without having to go to the basement every time you want to turn them on/off.

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 in my craft room where I don't have a lot of ventilation. Works great along with my air purifier. My only issue was it did not come with the hardware for mounting. Not too noisy on lower settings.

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

This works excellently as an exhaust ventilation fan. It is powerful enough that it pulls the tent walls in very well, so it definitely moves a good amount of air. It is not terribly quiet, but it is also very powerful, so that is the trade-off. There is no built-in timer, but I used it with a smart outlet when I wanted to give it a break now and then. Recently, I have had it running pretty much nonstop for the last few weeks with no issues. Overall, I would highly recommend it if you need a strong inline duct fan for ventilation.

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.
