Reseñas de clientes para Ventilador de conducto en línea VEVOR de 8 pulgadas y 750 CFM con controlador de velocidad variable, silencioso, con motor de CA, para refrigeración, carpas de cultivo e hidroponía.

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."

Controller screen burnt out in first five minutes now its useless !

This fan seem fairly well built but don't have the air flow i was expecting, they're ok considering the price point

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 bought two and installed it in my garage, I put an air duct to carry the dust out. He pulls a little, but comes back into the corners. I have looked at the position and it is correct. Now I have used one of the engines and I am out of a box to make the return. I just lost money.

DO NOT BUY. I purchased the 8 inch fan because the description says Quiet AC-motor. The advertisement states 38 db. It is actually over 80 db even at medium or low power. See my photo. IT IS VERY LOUD. VEVOR, please issue me a full refund and do not offer me $20 back as a suitable solution when your product is not as advertised. DO NOY BUY. DO NOT RECOMMEND.
