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

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.

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

Horribel build quality bent shaft, Vibration, Fan wobble, Noise is unbearable. I can not even have it running in the insulated attic on lowest settings in a sound insulated box, without being disturbed by it in the floor below. Tried to claim but rejected. do note recommend.

Fast delivery and good performance, but much louder than advertised Delivery was quick and the airflow performance is perfectly fine. The fan has smooth and precise speed control, which I appreciate. However, the noise level is significantly higher than expected. It is in no way close to the advertised 45 dB. I measured more than 60 dB during operation, which is a substantial difference and makes the fan far from quiet. I don’t know whether my unit is faulty, but based on my experience it does not meet the stated noise specifications.

variateur en panne !! après 1 an 1/2

Niet te veel verwachten van ogenschijnlijk goedkope producten. Ziet er leuk uit,, maar kwaliteit is niet veel. Ventilator is slecht geballanceerd en trilt/ rammelt bij hogere snelheden.
