ROCKFORD FAN CLUTCHES

The fan clutch standard bearer for the reduction of fuel consumption and fan-generated noise, prolonged engine life and improved productivity is now available from Viscofans.

Made for the toughest conditions

Through using either a standalone control system or an engines’ high-tech ECM, Rockford’s unique variable speed technology enables their fan clutches to respond to changes in engine cooling demands by intelligently varying the speed. The benefits of the Rockford system, by allowing the fan to slow down or speed up as needed, means applications utilize less working horsepower from the engine and help lower fuel consumption, thereby increasing the efficiencies of your applications.
