BHP Ð Brake Horsepower

NOTE: Extensive motor and electrical testing on the these units has en- sured that the full horsepower range of the motor can be utilized with

con®dence. Using your fan motors up to the horsepower ratings shown on the Motor Limitations table will not result in nuisance tripping or pre- mature motor failure. Unit warranty will not be affected.
