Oil-lubricated with crank drive unit (type KK)

Hofer piston compressors

HOFER piston compressors of the type KK are suitable for the highest pressures and for gases with special characteristics, such as ethylene or carbon monoxide. These compresssors achieve discharge pressures of up to 116,030 psi (8,000 bar).

If the gas has to remain nearly free of oil, separators or active carbon filters are positioned after the compressor.

Features at a glance

  • Discharge pressure up to 116,030 psi (8,000 bar)
