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.

Benefits

• Higher torque for larger fans and higher drive ratios
