Smoking Section Vent
Size: 6 Inch
I used this ventilation fan to remove cigarette smoke from a room. I bought everything from Amazon. The 6″ flexible ducting and the vent cover. I cut a hole in ceiling then connected the ducting to vent then to the ventilation fan, I then plugged the fan into a remote controlled outdoor power strip all in the attic. I can turn on the ventilation system anytime I’m needing the smoke removed and it works flawlessly and with hardly no noise. Very easy to install and is very durable and well made.

Extremely satisfied
Size: 6 Inch
I recently purchased the VEVOR Inline Duct Fan, 6-Inch 400 CFM, to replace the old fan in my kitchen hood. I must say, I am extremely impressed with its performance. The installation process was a breeze, and the powerful airflow it generates is remarkable. It effortlessly extracts kitchen smoke and odors, leaving my kitchen fresh and clean. The fan operates quietly, which is a huge plus for me as I can now cook without any intrusive noise. The build quality is excellent, and I believe this fan will last for a long time. Overall, I am beyond satisfied with the VEVOR Inline Duct Fan and would highly recommend it to anyone in need of an efficient kitchen ventilation solution.
The fan fits perfect, and the looks of it is durable and will last long due to the quality finish.

I love the versatility of the blower, many ways to mount it or just let it sit, I have a 4x2x5 and it’s does exactly what you need it to do

Size: 6 Inch
It’s not the same as the other ones that I purchased I really don’t like the way it locks in the fan unit basically because it has a plastic band that goes in two different directions and they are difficult to remove and lock back into the unit i

Received the product with no manual, no hardware screws to install it and a product much different from what is pictured and listed here, the mounting bracket was not metal as pictured it was a cheap plastic mount, that I am not confident will mount securely overtime the plastic feels very cheap on this as you will see in my pictures. I extremely hate when companies try to deceive people by showing you one thing but sending you something different or a possible returned product that wasnt inspected before they sent it, on top of that the controller I received was damaged. All 4 switch screw mounts were split from the screws and the dial was broken also, the dial upon turning it popped right off and the housing for the switch fell apart, it wont even hold shut. Needless to say I need a whole new switch with cord, currently I am not feeling very confident with Vevor at the moment, and the fact that this is now delaying my Co2 Laser engraving machine from running due to this issue. When I contacted there company about the warranty, they basically said they cannot help me because there Amazon ” Colleague ” is separate from there company and they are the ones who need to help me via email. because they cannot find my order they cannot warranty the device, themselves as the main company, that makes no sense to me whatsoever, especially when Amazon are the ones linking support directly to there website, Paola was the Vevor rep whom I spoke too. Hopefully they can resolve sending me a new switch or device I am not happy so far, with what I received, especially since this is mounted already. Either way please inspect everything you receive if you purchase this product. Lastly as far as the sound levels they are not too bad as one stated in a review here its not loud but its not super quiet either, once I can eventually get my ducting in I will know more on how good the sound is, this thing does produce good air flow tho. This get 3 stars for now till further testing not only of the equipment but also the customer service

Powerful but not as advertised
Reviewed in the United States on September 21, 2023
Size: 6 Inch
This model will put out an impresisve amount of air as advetised, is very lightweight, can be speed contolled, and is easily mounted. This is as far as the advertised features go as far as fact. The rest is a bold faced lie. The item clearly is advertised as 34db in noise(the baby sleeping picture). This is not even close. On low the fan puts out 52db and on high it puts out 71db. A 52db fan still puts out a good amount of air and would be tolerable if that 52db wasnt from an annoying electrical hum from the ac motor. Anything below aorund 60% speed and the hum is very noticable. This is due the the company no understanding basic principles of ac motor speed control. This is evident by the speed controller, which is just a basic, cheap, reostat. It just turns down the voltage to the motor creating the effect of slower speed. This is where the hum comes from. The speed controller knob is made so it sits crooked on the controller and the entire controller is blank from any markings indicating speed. I bought this mainly for the advetised low db. It is still better than what I was using before but I expect factual specs when I make a purchase.

As advertised

Unit preforms great and pretty quiet. Hook it to a vent that didn’t supply enough and was satisfy with the results. I would add some great pictures but Amazon app won’t let me paste fotos and I don’t like to allow access to camera or fotos.

Clears smoke from laser engraver but very cheap plastic!
Size: 6 Inch
Everything seems great with the exception of the on/off knob. It is extremely brittle plastic. In fact, the very first time I turned it on, the little bump that designates the on/off setting was too much for the knob to take and it literally snap in half…just rotating it to on!!!

Great fan at a good price

This fan worked great for days on end and I am very pleased with the purchase. Although the main reason to buy it did not work out I will use it in the future for some other projects.

Keep your expectations realistic…
Size: 4 Inch
This is one of the cheapest fans of this type on the market, and bearing that in mind, I’m not disappointed or impressed.
The fan itself is not particularly loud nor quiet, though it did require a bit of break-in to quiet down, but the motor has a crazy loud electric hum. It sounds like a bench grinder on a low setting. It can really permeate the room and even surrounding rooms. If it weren’t for that, I would be impressed.

Nice design.
Size: 6 Inch
Works great, has speed control and unit comes apart witch makes it easy to install in supply heat runs for my upstairs rooms that aren’t getting enough air and now they are. I put 4 fans in and fixed my upstairs HVAC problems.
