Very easy to maintain: Thanks to proven BAUER system components

Cost-efficient: Low installation overhead combined with cost-effective operation

Designed for demanding operating conditions: With optimum free air delivery rates and a variety of drive power ratings

Comprehensive assurance of spare parts supply: With the global BAUER Service and Support network

Whether they're found in standard compressed-gas applications in industry or built into vehicles for mobile use: The air-cooled high-pressure compressor units in the K 22 – K 28 series are reliable, durable and the solution of choice for demanding customers.

Outstanding ease of maintenance is just as much a matter of course for us as the wide range of possible applications – optimally matched to your specific needs.

The units of the new K 22 series are designed with direct coupling, while the units K 23 – K 28 are driven by means of V-belts.

In line with your individual needs and industrial requirements, BAUER KOMPRESSOREN can also provide you with tailor-made turnkey system solutions.

Colour range
Customer-specific paint finishes in other colours or special composition paints (conforming to corrosivity category C5M, for example) are available alongside the standard BAUER paint finishes.

Start-up configuration
Start-up configuration

Start-up configuration
At and above motor power ratings of 75 kW and in conjunction with the B-CONTROL, 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. Read more

Monitoring of pressure and temperature
This add-on module for the B-CONTROL control monitors the pressures and temperatures of all compressor stages. Read more

Intake system
Intake system

Intake system
The intake system supplies the compressor with air or gas at a suitable and monitored intake pressure. Read more

Intake pressure reduction
Intake pressure reduction

Intake pressure reduction
IIntake pressure reduction ensures that the compressor takes in the gas at the appropriate pressure. The level of intake pressure reduction is adjusted according to prevailing gas pressure and required intake pressure. Integrated safety valves and pressure monitoring effectively ensure that intake pressure does not fall below or above the permissible level.

Intake buffer vessel
Intake buffer vessel

Intake buffer vessel
To effectively prevent pulsations in the intake area, an intake buffer vessel is installed between the compressor and the upstream gas supply networks and/or control equipment. Read more
