Stratis Viscous Fan Clutch

Designed to cool the new hotter-running reduced emission engines, this revolutionary directly controlled viscous fan clutch (fan drive) can be managed by the engine’s electronic control unit for precision fan speed control. Its innovative reservoir, actuator and valve system deliver faster response time and lower off speed for maximum efficiency. The result is reduced fan noise and fuel savings.

Stratis is equipped with a rear mounted cable harness and the fan is uniquely installed on the front of the fan clutch to increase airflow and improve cooling. The integral fan speed sensor provides close loop control. An optimised magnetic design speeds up reaction time for better modulation and cooling. Plus, the fan clutch’s housing and cover have optimised fins to provide greater heat dissipation.
