Only from Horton-a world leader in fan drive technology-the DriveMaster Two-Speed Fan Drive alternates between eddy current and spring actuated cooling for precise, highly-efficient temperature control and reduced operating noise levels.
Under most operating conditions, the DriveMaster Two-Speed Fan Drive is powered by eddy current. This turns the fan at a low speed, which reduces ON/OFF cycling, operating noise, increases available horsepower for auxiliary systems, and minimises radiator abrasion from dust and debris.
When additional cooling is needed, the DriveMaster Two-Speed spring actuates, and runs the fan at full input speed. By supplying additional engine cooling only when it's needed, the DriveMaster Two-Speed delivers superior horsepower performance. Less noise. More power. Increased fuel efficiency.
Higher torque for larger fans and higher drive ratios
Up to 50% less noise
Reduced ON/OFF cycling at idle and/or low speed
Precise temperature control; ideal for vehicles with little or no ram air
Superior operating efficiency and performance
Quicker response to cooling needs
More available power to haul up steep inclines
Improved fuel efficiency
