Off-Highway Drives Arctis Two-Speed Fan Drives
Arctis Two-Speed Fan Drives offer a better, more efficient cooling solution for on- and off-highway vehicles without ram air. Rigorously tested, Arctis Two-Speed Fan Drives are engineered for reliability and long operating life in the highest-heat under-hood conditions.
The Arctis Two-Speed alternates between eddy current and spring-actuated cooling for precise, highly efficient temperature control and superior horsepower performance. Under most operating conditions, the Arctis Two-Speed Fan Drives are powered by eddy current—turning the fan at a lower speed. When additional cooling is needed, the Arctis Two-Speed spring actuates and runs the fan at full input speed.
