Cooling Fan Drive Clutches

Warner develops custom electromagnetic on-off fan clutches with various torque ratings to meet the specific application requirements. The compact fan clutch design provides the highest possible torque in a small package. The clutches are “ON” only when required, so up to 20 horsepower is not needlessly wasted turning the fan. A fully disengaged fan clutch means improved fuel economy, quicker engine warm-up, increased engine performance and reduced fan noise.
