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

I added this on my airbrush cabinet really works well.

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!

This worked well and is quieter than the one I was replacing, but it is louder than expected. It is quiet at very low settings, but noise increases very quickly with the speed.

I'm not much for doing reviews but these are good fans I have 3 of them running 24- 7 for over a year and still run perfectly people complaining about the noise it not loud but it is a blower fan of course there's noise but even 3 of them don't keep anyone up at night

Silent yet powerful. Does a great job of keeping wash fumes out of the room we occupy. Thank you!

Product had an extremely loud electrical whine, even on the lowest setting. Heard over other blower fans. Noticeable vibration while in use. PRODUCT CANNOT BE RETURNED. Future buyers beware.

Yes very nice unit works well

Great blower. Comes with what you need to get a basic setup. I am currently using it to hold a slight vacuum inside a 3D printer enclosure and vent to outside when printing. On it's lowest setting it moves plenty of air to pull fumes out and allow printing in my office. I smell absolutely nothing in my office now. Not sure how it compares to others, but so far have no complaints.
