Oil Lubricated


Our HOFER oil-lubricated piston compressors are designed for especially high-pressure applications (discharge pressures up to 116,000 psi/8000 bar), and can handle gases with special characteristics, like CO or ethylene. In applications where the gas needs to remain nearly free of oil, separators or active carbon filters are placed after the compressor.

  • Discharge pressure up to 116,030 psi (8,000 bar)
  • for gases with special characteristics (e.g. CO, ethylene)
  • stage pressure ratios up to 5
  • up to 6 stages
  • mass compensation for foundation-free installation
  • wear resistant and smooth operation due to low piston speeds
  • water cooling provides the best cooling effect as well as a low sound pressure level
  • manufactured in compliance with 2006/42/EC EC-Machinery Directive applied standards: DIN EN 1012 part 1, DIN EN 12100 part 1,  DIN EN 60204 part 1 et al.
  • explosion proof according to the European Directive 94/9/EC (ATEX 95), if necessary
