K22 – K25

SKU: G Series: K22 – K25

Bauer’s G series range of compressors provides innovative high-pressure system technology for the recovery, decanting and compression of helium, argon and other noble gases.

A low-maintenance V-belt drive, very robust and reliable unit components and low design make this series ideal even in difficult installation conditions and where space is at a premium.

Vapour recovery by the automatic condensate drain and integrated safety valves in the intake buffer and condensate vessels creates an enclosed circuit effectively minimises gas losses.

Low speeds and optimised grading of the compressors provide the basis for the very best compression ratios for the compression of noble gases.

Standard Compressor Package

* as of “standard version”

Please refer to Equipment Options for upgrades available for these models


  • Horizontal design with Robust dimensioning
  • Easy to maintain and Cost-efficient operation
  • Optimum free air delivery rates for your application
  • B-Control Micro fully automatic compressor control for the control and reliable monitoring of all basic functions
  • Standard compressor block series that is air-cooled
  • Designed for challenging industrial applications
Super-Silent cladding
Super-Silent cladding reduces the noise level of the compressor unit and enables an exhaust shaft to be used.


The BAUER B-CONTROL II compressor control is the extended version of the B-CONTROL MICRO basic compressor control.
Start-up configuration
At and above motor power ratings of 75 kW and in conjunction with the B-CONTROL II, a soft starter to protect the unit during starting and effectively reduce starting current is used as standard. The technical alternative is soft staring with a frequency inverter.
Monitoring of pressure and temperature
This add-on module for the B-CONTROL II control monitors the pressures and temperatures of all compressor stages.
Treatment systems
BAUER treatment systems for highly compressed air and gases reduce content such as moisture, oil and particles to a permissible level.
Storage systems
Modular high-pressure storage systems by BAUER KOMPRESSOREN are the ideal way to expand a compressor system.
