Dave Ok for the price
4"-260 CFM-4"a 3"
Low vibration when mounted vertically but not so much when placed horizontal. Does the job so far at lowering radon levels. Used with sump cover, 2" pipe and fan mounted in attic (shared with sewage ejector pit exhaust).

Good product will buy again. Seems like build well and shopped fast too. As I use more we will see how long it last.

Drew Good for the price.
Okay fan. However, the manometer that came with it has very flimsy tubing that pinches, so I had to buy a 3rd-party manometer for $15.
