Off-Highway Drives HT650 Fan Drive for Off-Highway Engines

The HT650 on/off pneumatic fan drive delivers significant fuel savings by engaging only when cooling is required. The HT650 completely disengages in off mode and is controlled by the engine, resulting in the best possible response time. The HT650 also provides ample torque -- without slipping -- from high-capacity fans.
