VEVOR Inline Duct Fan, 6-Inch 400 CFM with Variable Speed Controller, Quiet AC-Motor Ventilation Exhaust Fan for Cooling Booster, Grow Tents, Hydroponics

I bought this to use as a boat hull blower/dryer and it works great! This fits right on the seal of an 8” hatch I have on my bow and blows air throughout my hull. It helps dry it out while mitigating water buildup due to humidity keeping my hatches, pumps and everything else dry when not in use.

Works good, feels solid

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.

I bought this for my main, full bathroom in a custom down vent set up. Works great and is quiet, even on full.... No more walking out of the bathroom like a WWE entrance.

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.

Bought this to pump air through a filter unit in a chicken coop. It works well enough that I am often cleaning the actual vent I installed because it’s getting clogged! I wasn’t sure it was strong enough, but the amount of dust and dander that’s getting sucked through says otherwise. There’s definitely a sound to it, I wouldn’t call it loud, but it’s louder than you’d think it would be. Great price. Very sturdy item. So far, no complaints.

Like the way it was packaged 📦 and looks to be made of good quality!

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!

Works as advertised. However, there is a small issue when blowing air through an filter which causes more resistance. Doing this on lowest speed setting will blow out the speed controller and thereby stop the fan from running at all. Not an issue for me as I was just running some tests.

Good item, works very well. It came quicker than stated which was good. Seller was very helpful, they kept me up to date all the time and were very friendly, i highly recommend.

Broke after 6 hours of normal use. Do not recommend.

DO NOT BUY! Don't ignore the other reviews stating its loud.. They are accurate. The variable speed doesn't seem to work at all and the unit emits a concerning electrical buzz while operating. absolute trash product

Muy buena turbina y succión = buen flujo y renovación de aire 👍🏽👍🏽 algo de ruido a máximo de e potencia pero es normal.
