Product Reviews

Rated 5 out of 5 by from exact replacement This NuTone ILRF Radon exhaust fan was provided by Venting Direct as an exact replacement for one which failed at my house after eight plus years of continual 24/7 service. The original fan re mediated radon from underneath our basement concrete slab and vented it through the roof of our house through all seasons here in Pennsylvania with no noise or failure for those eight plus years. Apparently, the bearings or some similar part of the original internal fan finally succumbed to the elements and needed to be replaced. Venting Direct provided the replacement in a courteous, reasonable, and prompt manner. It was very simple for me to replace the original, even though it is at a part of the attic which is trouble some to work in. I feel the original unit lasted very well, and would highly recommend this fan to anyone needing a similar device.
