Fantech® RN 4EC-3 Inline Radon Fan W/ EC Motor, 4.25" max SP

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 4.8” of suction while moving 20 cfm, as well as move 203 cfm when operating at only 0.5” of suction. High airflow, 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. The integrated control system allows for “dialling in” the fan speed necessary to achieve either the required sub-slab depressurization or required system airflow rate. For demand-controlled systems, the potentiometer can be removed from the wiring terminal block to accommodate an externally-provided 0-10Vdc speed command.
