Oil-Flooded Rotary Screw Compressors

The heart of most industrial compressed air systems is the oil-flooded rotary screw air compressor:

  • 5 – 500 horsepower
  • Single or two-stage
  • Air or water-cooled
  • Direct drive models
  • Energy-efficient designs
  • Complete line from Quincy and FS Curtis.

Scales’ variable displacement and variable frequency drive units can provide the ultimate solution in part-load energy efficiency and savings.
