Active radon mitigation systems employ specialized fans to exhaust radioactive radon gas from underneath building structures via a sealed pipe system. These systems are designed to remove radon gas before it migrates into the building envelope.

The Rn2 is ideally tailored performance curve for a vast majority of your mitigations that require medium air flow and 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.

A large electrical wiring enclosure is designed into the fan housing, making electrical installation easier. Thermal overload protected with automatic reset.

The fan can be mounted both indoor, outdoor and in wet locations.

Performance certified by HVI; safety certified by UL.

To simplify installation, use FRIK 4x3 or FRIK 4x4 Installation kits.
