RadonAway RP140C 4 in. Inlet and Outlet Inline Radon Fan in White with 0.7 in. Maximum Operating Pressure

The ENERGY STAR Rated RadonAway RP140c Radon Fan is intended for use as a component of an active soil depressurization (ASD) system for reducing radon. The RadonAway RP140c Radon Fan is ideal for new construction and retrofit, providing superior performance and ultra-quiet, energy-efficient radon reduction. Designed for lower pressure and average air flow, the RadonAway RP140c Radon Fan provides an especially efficient choice for very porous sub-slab/sub-membrane material (that is 4 in. of clean, size 4-6 gravel) and can be used for slab/membrane sizes up to 1600 sq. ft. The RadonAway RP140c Radon Fan is built to resist moisture and can be mounted inside or outside on a 4 in. Sch. 40 PVC vent pipe using 4 in. x 4 in. flexible couplings. NOTE: When installing an ASD system for radon reduction, any openings, major cracks and penetrations in the building slab or membrane must be sealed. Fan sizing for retrofit may require professional diagnostics and design.
