DM Advantage® Two-Speed Fan Drives for Off-Highway Applications

DM Advantage Two-Speed Fan Drives alternate between eddy current and spring-actuated cooling. While using eddy current, the fan drive turns the fan at a lower speed, which reduces operating noise, increases available horsepower for auxiliary systems and minimizes radiator abrasion from dust and debris. It spring-actuates when more cooling is needed, running the fan at full input speed. It also provides faster engine warm-ups in cold weather.

Applications

  • Heavy-duty trucks
  • Medium-duty trucks
  • Variety of off-highway equipment
