On-Highway Drives HT650 On/Off Pneumatic Fan Clutch

HT650 On/Off Pneumatic Fan Clutch

The HT650 On/Off Pneumatic Fan Clutch engages only when cooling is needed, resulting in reduced horsepower and fuel consumption. In the off mode, the HT650 completely disengages. The HT650 is engine controlled, providing the best possible response time. When engaged, the HT650 can deliver the maximum torque required by high-airflow capacity fans, without slipping.
