Is the radonaway rp140 a good fan?
Lesson Learned. I installed the RP140 to replace another radon fan which was really overkill for the application, and thus was quite noisy. The RP140 was sufficient to reduce the radon level to where it needed to be (I have a monitor) and initially was very quiet.
