Customer Reviews for VEVOR Inline Duct Fan, 203.2mm 506.2 CFM with Temperature Humidity Controller, Quiet EC-motor Ventilation Exhaust Fan for Cooling Booster, Grow Tents, Hydroponics

The fan works well, good speed control, reasonable noise (most of the noise in my case comes from the air duct), and easy settings. However, the product page used to state it was suitable for all temperatures, which is misleading. The manual, information that isn’t obvious until after purchase, shows a strict high-temperature limit. This makes it unsuitable for HVAC heating applications in winter. If Vevor offered a blank plug to replace the motor for off-season or heating use, it would be far more versatile. Works fine for cooling or ventilation, but not for winter heating ducts.

Pour prévenir d'entendre le bruit de silement du moteur, il est préférable de le suspendre avec de la ficelle. En dehors de cela, je suis satisfait.

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.

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.

O aparelho faz muito barulho mesmo na velocidade baixa tem 43.7dBA e na máxima velocidade tem 63.8dBA . Se for para usar como VMC dentro de casa não compre , faz imenso barulho.

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
