Heat Removal N/A Oil Cooler = Compressor Horsepower x 1.15 (motor service factor) x 0.83 (this assumes 83% of input horsepower is rejected to heat)
Aftercooler = Compressor Horsepower x 1.15 (motor service factor) x 0.17 (this assumes 17% of input horsepower is rejected to heat)
Features N/A
  • Complete Package includes aftercooler/oil cooler, fan, motor, guards and mounting brackets.
  • Convert Water cooled compressors to air cooled. Eliminate corrosion and expensive water bills.
  • Remote Mount the cooling package from the compressor to reduce noise, or to a cleaner, cooler, more convenient location.
  • Canadian Registry Numbers Available
Note N/A
  • Electric motors are totally enclosed, and are not thermally protected.
  • Actual ratings vary with motor brand. Check motor nameplate for actual ratings.
  • Motor RPM is reduced by 1/6 for 50 Hz service.
