Customer Reviews for VEVOR Inline Duct Fan, 102mm 129.7 CFM with Variable Speed Controller, Quiet AC-motor Ventilation Exhaust Fan for Cooling Booster, Grow Tents, Hydroponics

I picked up one of these fans due to its high airflow and rated static pressure rating of 300 Pascal's. The fan, as delivered, is only able to achieve 100 Pascal's of peak pressure, at which point the airflow drops by a factor of 10. I intended to use this with a filter as a low-noise fume extractor; but due to the very poor pressure handling (which I shouldn't be surprised at with a 68W power rating!) it's completely unsuitable for this application. In its intended use of home or small-space ventilation, with sufficient make-up air to maintain a sub-100 Pascal pressure differential: it does absolutely meet and exceed it's 800CFM rating. Had I used is strictly as designed: it's a pretty decent fan! For my purpose, the fan is rated incorrectly and this should be updated.

The fan seems to be working well. It is pretty noisy but other than that all good Ive got it set up in the basement for a radon exhaust fan

There is a constant hum that sounds like a stalled electric motor, but it does not change pitch with speed. I don't know if that's normal or not. It uses 70w/1.5A on high. Seems quiet otherwise.

technischer Defekt

I never received it. It was delivered to the wrong address or the porch pirates got it. Fortunately, I didn't need it as the current one resurrected itself.

I’ve had it for two years now, and it’s still working great. Cons: The hose is stiff. Pros: Low price, reliable quality, fast delivery. If you want something reliable and quiet—and three times the price!—then buy "AC Infinity."

Unit is quiet but has very, very little suction.

It does the job but it also allows dust/smoke to blast out the sides of the fan, not very quiet unless on lowest setting, vibrates like crazy nothing that I can tell of is imbalancing the fan I assume it's in the motor

variateur en panne !! après 1 an 1/2

Le variateur ne fonctionne pas donc raccordement en direct.
