HK Hydraulic Piston Compressor

DYNASET HK Hydraulic Piston Compressor converts the hydraulic power of a mobile machine, vehicle or vessel into compressed air.

The HK Hydraulic Piston Compressor converts the hydraulic power of a mobile machine, vehicle, or vessel into compressed air, offering a compact and efficient alternative to large diesel-powered compressors. Its lightweight and space-saving design makes it ideal for mobile applications, including use with drilling rigs, tractors, and excavators. The series has also special oil-free models provide additional versatility with position-free installation, use, and transportation, while requiring less maintenance and producing cleaner airflow.

How Does the Hydraulic Piston Compressor Work?

The hydraulic compressor uses a machine’s, vehicle’s, or vessel’s hydraulic system as its power source to produce airflow.

  • Hydraulic oil flows to the hydraulic compressor’s integrated hydraulic motor through the pressure line.
  • The hydraulic compressor converts hydraulic oil flow and pressure into compressed air.
  • The hydraulic oil is returned to the carrier machine’s hydraulic oil tank via the return line.
  • The compressor’s piston generates air pressure, which is directed to the reservoir frame and utilized, for example, to power pneumatic tools.
