Customer Reviews for VEVOR 4 Inch Inline Duct Fan HVAC Exhaust Blower Kit EC Variable Speed Control

Best value in 6inch exhaust

The control unit for this fan is great and easy to use. The blower action has a reasonable noise level, but because it is not perfectly balanced, the unit vibrates and creates a low-frequency rumble. I wouldn't want to use it in an area that I occupy often.

Grei kraft i viften kan justeres etter behov har brukt den til avtrekk i sandblåser. eneste minus er att det er litt kort ledning

Super very good suction power, as described in the product page. The wired controller is usefully and provides all necessary information.

I just got this fan a few days ago to replace a noisy relatively power hungry inline fan i already had. My first impressions are pretty good. I haven't installed the fan how I want yet, but I have messed around with it. First off, the description says it's 68 watts, I hooked it up to my kil-a-watt, and at maximum speed, it only draws 59-60 watts. So that is deffinately a bonus. While down at speed 2, it draws about 11 watts and still moves a decent amount of air. I do not have an anemometer or anything to verify flow rates. As far as noise, I haven't checked it with a decibel meter, but it's not the loudest fan in the world. Speed 2 you almost can't hear it, at 3 you start being able to because the Humm it creates is sort of a higher pitched Humm, not a deep lower tone. At speed 10, it gets kind of loud but not the loudest fan I've had. This review could possibly be premature, but overall I'm satisfied so far.

Great operation, easy to install , LED Screen 10 levels and Quiet! Quality built!

Super god ventilator, med mange indstillings muligheder. Kraftig sug. Men der er ikke helt uden lidt larm.

I purchased this unit and attached it to a 4” flexible hose, attached the hose to a dust collector shute and vented to the outside. It is surprisingly quiet for the amount of air it pushes and quickly removes the vast majority of the smoke and fumes created by the laser. I would highly recommend. Way better than the “solder, welding, nail polishing” units that are currently over promising functionality

Installed in sun room. Sadly this unit size not powerful enough to do an adequate job.

I used this in my bathroom, and the system works exactly as I planned. I installed the sensor probe in the vent grill, and the fan activates as soon as the humidity level reaches the set point. It’s amazing! This unit offers more functionality than other expensive models I purchased previously, which I had to return due to their lack of user-friendliness. I hope this helps!
