VIVOSUN R6 6" Inline Fan, 390 CFM for Grow Basement Bathroom Kitchen Attic

So, I'm using this fan as part of my custom built ventilation system in my basement room converted to a cigar room. I use it to suck the cigar smoke out through the window via the 6 inch hose and some ducting that goes out. I use it in conjunction with a duct fan that's hooked onto the HVAC ducting that acts as an intake fan for the same room. What I like. 1. The speed controller comes attached. No need to purchase one separately. 2. Durable. I had a mishap where I accidentally dropped it from 7 feet to a concrete floor. No problems, turned it on and fired right up. It's plastic on the outside, but the fan itself has some good heft to it. 3. Powerful. This thing cleans out a room fast. You can watch the smoke going from the cigar a good distance away in the room as it goes right to the area of the fan. What I don't like: 1. This thing is loud. But, that's the compromise. If you want a proper fan that will do the job, noise will be on the table. That all said, it's not loud enough to drown out conversation or music on a small speaker in the room. Further, it's powerful enough to run on low and still keep the room clear with one or two cigar smokers. In all, this being part of my ventilation system saved me hundreds of dollars by not buying a rabbit, or any other overpriced smoke eater. Good price, quality fan.

Installed in-line on a 6-inch HVAC duct to increase airflow to the second floor bedrooms 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: really not any. Since sound travels in the ductwork he may consider it loud, however it’s about the same as having a fan running in your room. This is the ideal model if you’re trying to push more air to a bedroom. 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 this model 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, and also allows you to set them to a timer through an app so you don’t have to run them all the time. I only run them from 7-9 at night when the A/C begins to cool the house for the evening.

I was upset about the noise level of the fan. That still holds, but am quite impressed that it has been running 24x7 for about three years now. Original Review: Poor motor isolation One of the 2nd floor bedrooms has poor air flow and is too cold in winter or too hot in summer. I installed this booster fan in the 6in duct in the basement feeding the room just before it transitions to an in-wall duct. My decision to select this product was: + the fan housing enlarges to about 10" diameter. This prevents the motor taking precious area and reducing the available cross-section area for air flow which effectively chokes the fan. + Includes fan speed control to tune the air flow + Large number of positive reviews on Amazon The installation was fairly easy once you cut the galvanized duct to the proper length. Since my basement has a finished ceiling I had to install inside a closet where the duct was exposed. I removed a section of the duct that is almost the length of the entire booster fan assembly and secured with 6" hose clamps and sealed with aluminum tape. Once running, it gives a good boost with a reasonable amount of wind noise at the floor register. With the fan control set at about 1/3 the speed range it gives a good flow (about a 12ft rise to the 2nd floor bedroom register). The downside is that there is a humming noise transmitted throughout the entire galvanized duct that is quite noticeable. The noise does not carry to the second floor, but is quite audible throughout the first floor and basement where all the registers are connected via galvanized ducts. You can hear the hum under the1st floor where the ducts run under the floors. I measured the sound levels with my phone: 1ft from the booster in the basement: 23.9db (fan off) / 43.2db (fan on) In the finished area of the basement (home theater): 29.1db (fan off) / 33.5db (fan on) 1st floor dining room (right above the duct with the booster installed): 20.9db (fan off) / 48.0db (fan on)

I bought this fan to suck the air off of my fiber laser when engraving things such as plastic or wood. This fan really has some suction. There have been times when it has sucked a piece of paper from across my desk into it! I highly recommend this product if you need a compact way to move large volumes of air! Not to mention this thing is incredibly quiet!

Bought this to replace a chintzy 6 inch inline fan that was squealing. It Arrived quickly, well package, and moves air very efficiently. It is quiet and well built. Mounting plate is easily installed and holds the fan securely. Everything about this fan is 5 star BUT, I just installed it, so I can speak for it's longevity. Based on everything else, I would guess this fan will last a long time and work well the entire time. I'm glad I paid a little extra for it and would make this purchase again.

I hooked this up to my laser enclosure with 4-to-6 inch adapters. This moves a lot of air so no, it's not extremely quiet. But when the laser is running and its tiny high speed fans fire up, they completely drown out this fan. And this fan is quieter than the air filter I had been using. I needed more air flow so I'm skipping the filter and just piping the air straight out a basement window.

I have this fan attached to my ductwork in the basement to push some of the cold air down there into the upstairs area. At 390CFM, this is perfect for our 2000 sq ft house. It is right below our master bedroom and I can barely hear it at night when I am in bed - the dehumidifier down there is far louder.

I've spent months putting together the funds for, researching and buying items to set up a 36"x36"x72" grow tent in the corner of my bedroom to grow my own medicine. I read lots of customer reviews on Amazon, even read in some online groups and forums that this 6" inline fan scored high marks from other users. I have to agree with all but 1 of the praises, that being the noise level. I have 4 fans on my LED light, 2 more 8" independent fans for circulation inside the tent and an 18" oscillating pedistal fan outside of it and this 6" inline fan (connected to insulated duct) is louder than all of them together. The reviews say it's a quiet fan, which leads me to believe that I may have gotten that one bad apple, but I need it to keep down the heat from ruining my plants so I'll endure it for a couple months. I have several other Vivosun products/tools that do not disappoint. Re: Upon contacting the company and working with them on this subject they issued me a full refund and told me to keep the fan. I had continued searching for a solution/quieter fan I found that VivoSun also makes a noise dampener/quietener filter that fits inline along with the fan. Wouldn't you try to sell me that with the issue I'm having instead of, "Here's your money back, don't know what to tell you. Keep the loud fan as our gift."?

Preisgünstig, recht leise und leistungsstark. Der Bereich für den Drehzahlsteller sollte noch etwas weiter nach unten gehen. Praktisch, der Halter mit "Klickverschluss". Erleichtert die Montage.

Brilliant fan! Its such a relief to have installed this in my attic for my bathroom. We have a ceiling standard 140mm which was so noisy!!!! It sounded like a aeroplane everytime you turned the light on. Not the case with this little badboy! Comes with a wired plug. I removed this and installed a fused spur fed from the bathroom lights. Best thing I have ever done. No more water condensation all over my walls and ceiling. And bonus is the speed is adjustable, so you can speed down in summer so its even more silent and up again in winter.

it has now been 6 years that this fan has been running 24/7 without any signs of letting up. who ever comes back to write a review about something they bought 6 years ago and didn't have any issues with it, unless it exceeded their expectations, right? yeah... let that serve as the only review you need to read.

Using It for Laser Fume Extraction Quite Good Output Low consumption of power only 42w

Fan Vivosun :Très bien et silencieux.
