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.

As the most powerful model in Fantech’s family of Radon Mitigation fans, the Rn 4EC can create 4.3” of suction while moving 20 cfm, as well as move 490 cfm when operating at only 0.5” of suction. High air flow, high suction.

Rn 4EC features an electronically commutated (EC) motor. Inherently efficient and operationally stable at full and reduced speeds, the EC motor arms the radon professional with installation methods not previously practical. Integrated control system allows for “dialling in” the fan speed necessary to achieve either the required sub-slab depressurization or required system air flow rate. For demand-controlled systems, the potentiometer can be removed from the wiring terminal block to accommodate an externally-provided 0-10Vdc speed command.

The Rn 4-4EC is constructed with UL certified, UV protected polycarbonate material. The inlet and outlet pieces of the fan’s housing are vibration welded for 100% leak-proof housing construction. Totally enclosed motors are designed with extra moisture protection in various radon applications.

Performance certified by HVI; safety certified by UL.
