How Does the Hydraulic Screw Compressor Work?

The hydraulic compressor utilizes a machine’s, vehicle’s or vessel’s hydraulic system as power source to produce air flow.

  1. Hydraulic oil flow is led to the hydraulic compressor’s integrated hydraulic motor through the pressure line
  2. The hydraulic compressor converts the hydraulic oil flow and pressure into compressed air
  3. The hydraulic oil is led back to carrier machine’s hydraulic oil tank through the return line
  4. Intake air is compressed between male and female screws. The compressor’s screws are driven by hydraulic motor.
  5. The screw compressor is equipped with oil heat exchanger which transfers the heat to carrier machine’s hydraulic system for cooling.
  6. The hydraulic screw compressor can run continuously 24/7 without stopping. The compressor will run on idle speed when it does not produce air flow.
