As the most powerful model in Fantech’s family of Radon Mitigation fans, the Rn4EC can create 4.3” of suction while moving 20 cfm, as well as, move 490 cfm when operating at only 0.5” of suction. The Rn4EC 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. Located in the wiring box, an integral speed control potentiometer can be used to “dial in” the fan speed necessary to achieve either the required sub-slab depressurization or required system air flow rate.
