VEVOR Inline Duct Fan, 8-Inch 750 CFM with Variable Speed Controller, Quiet AC-Motor Ventilation Exhaust Fan for Cooling Booster, Grow Tents, Hydroponics

Excellent so far after a week of use. I installed this to provide active fresh makeup air for my range vent exhaust. Inline with a damper that feeds directly into my HVAC air return, this fan and easily adjusted speed controller has allowed me to balance interior pressure with the highest setting setting my middling 375cfm hood fan can provide. In testing at full speed, it was able to pressurize the house by about the same amount my hood was depressurizing. So for the money, these fans definitely seem to meet their rated airflow spec and really do move a LOT of air. Mounting it on a shelf was super easy. Using rigid ducting was an easy fit, crimped or uncrimped. Just pay attention to how the motor housing assembly can fall apart after removing it from the bracket for mounting. It's not a big deal and easy to figure out how it goes back together, but the interior venturi bezel is not fixed in place when the motor section is removed and may fall to the floor if you aren't careful. It's also reasonably quiet. I can hear a slight humming sound through the wall into the adjoining kitchen when it is on, but that is likely because I did not use the isolation feet though, so that is on me. In the garage where it's mounted, I can scarcely hear it at all over the central HVAC fan running. Obviously, wiring requirements may vary, but having a plug has been a convenient extra (with a smart outlet currently controlling it) until I can get it hardwired into a proper makeup air control from my vent hood.

It's definitely not whisper quiet but it's quiet enough to go in my crawl space and not be heard in the house which is what I needed. It directs the air almost like a tunnel so it works great to circulate versus a fan that spreads out. On medium power you can feel the wind from 10ft away!

Don't rely on the description. This fan moves a lot of air, but it is not quiet. it makes way too much noise at all speeds to be useful in a living environment. Might work for a shop, but not in your dwelling. At high speeds it moves a lot of air, and makes noise from the air flow. This is understandable. But at low speeds it vibrates and rattles annoyingly, making it unusable. All this would be OK, if you could return it. I opened the package and plugged it in sitting on my kitchen counter top. It was too loud at all speeds. I put it back into the packaging with all the unopened parts that came with it. When I filled out the return form on Amazon, it responded the item was not returnable. So, I guess I will throw it out or give it to Goodwill. Needless to say, I am not happy at all with this item and the return policy. I will likely not take a chance on Vevor products in the future. All in all, the value to me is worthless. The noise level is high. The quality is low. The performance is OK if you can stand the noise.

Runs great! Great price!

Well loved how easy it was on installation and everything was in the box . Wasn't much there 👍🏼, anyway I continued to put it to my tent and plugged it in hopeing all was good and well listen u tell me is that ok ? Running 24/7 daily .I thought it was a lil better than those metal 1s only thing thats better is it's plastic not finger splitting metal ,but they are a lot quieter, the finger choppers see ya !! why these should be at least what they claimed quiet,etcetcetc listen is that quiet ? It's not bad glad I grabbed it !! Lil louder but she's a runner .and update she's a runner not bad at all loving it .

NICE QUITE PLASTIC UNIT. BUT....... DO NOT USE FOR HIGH HEAT HOT AIR USUAGE. IT WILL MELT THE PLASTIC FAN. FOR HOT AIR USAGE, BUY ALL METAL FAN.

Clean

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

la fixation inférieure est difficilement accessible, il n'y a pas de gabarit de perçage par exemple, produit pas mal mais qui pourrait être mieux avec quelques petites améliorations

Ni un ruido casi perfecto

La turbina funciona bien, tiene un gran caudal de aire como promete. Hace un ruido acorde a lo esperado, no es ni demasiado ni tampoco silenciosa. El potenciómetro ha muerto en 15 minutos.

Je craignais le bruit, il est plutot silencieux pour le volume d'air brassé. Tres satisfait. Sur le débit : Vitesses max mesurées en sortie : Régime minimum : 4m/s sur les pourtours de la bouche Régime max : 13m/s Ce qui donne en prenant en compte la surface non utile de la bouche (anneau de 3cm de large pour 20cm de diametre max): 750m3/h de soufflage max en régime maximum 230m3/h en régime minimum Environ 300g de poussée horizontale en régime max

Facile à installer et efficace. Cependant très bruyant. Ok pour un garage. Ne pas installer en appartement.
