RCV250 Fully Variable Fan Clutches

Lighter with a compact design, Modulator™ RCV250 Fully Variable Fan Clutches are engineered to turn larger fans that require higher torque.

Modulator is an integrated belt-driven fan clutch that can be mounted in various locations to eliminate the vibration inherent in traditional driveshaft-mounted fan clutches.
