Rockford Powertrain Fan Clutch

Rockford® introduced its first on-highway Class 8 truck fan clutch over 25 years ago and has continued to apply and refine the technology for off-highway applications ever since. Today, their high-performance fan clutches continue to set the standard for reduction of fuel consumption and fan-generated noise, prolonged engine life, increased belt life and improved productivity.

Rockford's unique variable speed technology enables fan clutches to respond to changes in the engine cooling demands by varying the fan speed. This allows the fan to slow down or speed up as necessary, utilizing less working horsepower from the engine and lowering fuel consumption.

Their fan clutch is offered in various sizes. Each fan clutch series number relates to its relative size within the product family. They currently offer fan clutches for engines from 400 to 4,000 horsepower which use cooling fans from 10 to 300 horsepower.

Benefits Include: Increased fuel economy and usable horsepower Eliminates shock load on engine components Lowers noise for decibel rating Permits programmed fan speed clipping at high engine speeds Enhances operator comfort Increases productivity Increases fan belt life Reduces radiator sandblasting Reduces fan blade erosion
