Customer Reviews for VEVOR 4 to 4.5 inch Radon Fan Installation Kit, Quiet 190CFM Radon Mitigation Fan System Kit with 2 Couplers, Pressure Indicator, Waterproof Inline Duct Fan Exhaust Fan for Indoor Outdoor Ventilation

I bought this radon fan about a year ago but never got around to installing it because my existing one was still working. The existing one was getting noisier and noisier, so I finally changed it. It was easy to install and is much quieter than the old one and there is no vibration. I checked at the outlet outside, and it is moving a lot of air. So, I am totally satisfied with this radon fan. It seems to be well-built also.

Zuverlässiger Liefetant. Gerät funktioniert einwandfrei und ist einfach zu installieren. Gerne wieder!

The fan does what is claimed and in our install is working nicely. What is really impressive is how quite it is in comparison to other fans I have done in my prior houses and now my son's house. I cannot confirm that is is truly 260CFM but can say that it manages to pull from the sump pump enclosure very effectively (better than /10th the radon post mitigation). A couple of considerations that I will note: 1. The instructions are minimal at best, so know in advance what you need to do. 2. The provided tubing for the "Pressure Indicator" is really short (like 8 inches long) and therefore presumes that you are going to mount the gauge to the pipe. The holder for the gauge would have you use screws, but you don't want to screw into the pipe. They provide a long twist tie, but I don't see that holding the gauge up on a vertical pipe. No two sided adhesive is provided so you will need something. 3. The instructions show the device mounted sideways (flow going horizontally). This should be avoided where installation will have a vertical exhaust port (like up the side of the building to be more than 6 feet from any opening into the house). In a vertical install you need to be prepared for moisture (rain to drain down through the pipe, past the fan, and into the floor. If the fan is mounted horizontally the moisture will pool in the fan enclosure.

I can’t get over how quiet and efficient this unit is.

My husband was able to install this himself, the instructions were easy to follow and after a trip to the hardware store we had everything we need. We have our radon reader still set up and it works really well! So happy this worked! Way cheaper than the one at the store by us, which is funny because we read the UPC and it is the same unit.

Excellent excellent

Super schnell und top wahre

Excellent product. Recommended!

Seems like good quality product. Everything as promised

Much stronger than my old 145cfm fan. Now my manometer actually reads something when the fan is running. Seems to have lowered my average radon levels from 4.5ish to 2.5ish. hard to tell with radon as it constantly fluctuates but if your seeing less than an inch on your manometer and have a lower cfm fan installed you will likely see positive results if you upgrade to a higher cfm fan like this one depending on whe you currently have installed.
