  • Key Features
  • GEA Grasso Gas M Series
  • GEA Grasso Gas LT Series

GEA Grasso – Gas Screw Compressors

Screw compressors operate by drawing gas into the spaces between the lobes of two rotors. As the rotors turn, the gas is forced by the rotor profile into continuously decreasing space until it reaches the discharge port of the compressor. The compressors do not generate out-of-balance forces; therefore, they require significantly low foundation strength.

Advantages

  • Outstanding efficiency
  • Extremely long operating life
  • High availability
  • Easy & low maintenance
  • Wide range of suitable gases
  • Flexible design customisation according to various guidelines
