VEVOR 8 inch Inline Duct Fan 750 CFM Ventilation Exhaust Fan Low Noise | for Cooling Booster, Grow Tents, Hydroponics, Quiet AC-Motor, with Variable Speed Controller, Vibration-Free Rubber Mats

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!UPDATE: Went down to the crawlspace and the fan is no longer running.. Not sure exactly how long it lasted but roughly one year.. It was on 24/7 at medium speed in a crawl space with ~45-55% humidity. So for only one year life span not impressed.. The cheap oscillating fans are still running..

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.

Great inline, it’s a little loud so I had to mount it under a covered rooof outside of the shop but it pulls in a decent ammount of air. Priced good also and shipping didn’t take forever

Powerful but very loud

I used this with an 8 inch shop vac filter attached to collect ambient dust in my shop. Installed just in front of my mini-split AC to prevent saw dust buildup in those hard to clean places.Quiet and efficient.This is the fifth Vevor purchase I’ve made from hose winders to drill press and each has been exactly perfect for its intended use.A clear winner.

Works great! We got a timer/thermostat to put on it. My husband retrofitted it for our chicken coop. If it gets over 95* the fan comes on to move the air around. Then goes off when it gets cooler. Gotta keep our hens happy!

I have the 820 model, it's been running flawlessly since I received it. Highly recommend the vevor products. The 750 has a spin switch for speed, the 820 has a digital

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.

El producto no está mal, es robusto y potente pero mucho más ruidos de lo esperado, trámite la devolución y sin problema

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

Me vino rapido, lo instale estubo funcionando una ora y ya paro al final lo tube que tirar,no funcionaba...
