6" RADON DUCT FAN

The Rn3 models is an excellent choice for systems with elevated radon levels, poor communication, multiple suction points and/or large sub slab footprint. High air flow, medium suction.The fan features a fully sealed plastic housing. The inlet and outlet pieces of the housing are joined via a vibration welding process. The process uses transverse, reciprocating motion under pressure at the point of contact. The friction produces heat that melts the thermoplastic material at the interface. The melted material quickly re-solidifies, resulting in a fused, single piece housing. The fused seam is inherently air tight, very strong and permanent.This air-tight product ensures that efficiency is not lost and contaminants are not spilled due to leakage.
