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, our line of high-performance
fan clutches continues 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 our 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.
Our fan clutch is offered in various sizes. Each fan clutch series
number relates to its relative size within the product family. We
currently offer fan clutches for engines from 400 to 4,000 horsepower
which use cooling fans from 10 to 300 horsepower.
