Customer Reviews

Rated 3.0 out of 5 by 1 reviewer.
Rated 3.0 out of 5.0 by Easy to install, but loud Installed this fan in my attic and found it easy to mount in an existing pvc radon tube. However, the fan is loud and tends to vibrate from the attic with noise into the bedroom below despite rubber fittings on the tube and separate rubber suspension straps I added. Look for a quieter fan. December 13, 2011
