Radon Rid uses Radon Away fans. The highest quality fan in the industry.
- Energy Efficient
- Designed to allow water to filter through exterior fan housing
- Five year warranty on performance
- No air leakage
We use a switch box with a lock for outside radon mitigations. Radon fans are always running and while NRPP requirements call for a turn off switch, the fans should never be turned off. Radon concentrations will go back to normal levels in just a few short hours.
Which fan is chosen depends upon the vacuum pressure needed, based upon sub-slab conditions, and air volume needed which is based upon cavity sizes and tightness of the slab.
A bigger fan is not always the best option. Oversized fans can bring excessive noise and energy loss and problems. Careful attention to the design of the system is more important for homes that may need larger fan systems.
If the Radon mitigation system needs to move large volumes of air, the pipe is more important than the strength of the fan. 3″ pipe moves up to 80 cfm while 4″ pipe moves up to 150 cfm.
The Radon fan needs to be set in an unoccupied space due to the possibility of an exhaust leak. The Radon fan must be outside or in an attic and doesn’t have livable space above it. It can be in a garage if it has exposed rafters/trusses.
