Open or closed design: Tailored to meet the needs of your application

Fully automatic compressor control: B-CONTROL MICRO

Little space required: Thanks to compact horizontal design

External P 120 filter system: External P 120 filter system: Providing clean breathing air conforming to DIN EN 12021¹, the standard for breathing air 15,000 m³ of air can be treated

The KAP 23 series by BAUER is able to meet exacting performance requirements under the toughest conditions in professional applications.

These powerful horizontal stationary compressor units are available in open or fully closed versions for both PN 330 bar and PN 420 bar.

Evidence of more than 65 years' experience and the excellent know-how of our test and development centre can be found in every one of the powerful compressor blocks.

The key characteristics of the blocks, which are the result of absolute dedication to design, intelligent in-depth solutions and high-quality materials, combine outstanding reliability and long service life.

The 4-stage construction of the compressor blocks (IK 23) and the use of high-performance industrial ball bearings along with plateau-honed plasma-nitrided cylinders are the key to the units' extremely long service life.

The high-pressure final stage is equipped with piston rings featuring a special chrome-plated finish. A zero-maintenance low-pressure oil pump is responsible for the safe and reliable lubrication of the surfaces of the cylinders.

Operators can choose from a selection of electric motors and diesel units to drive their applications.

¹ If the units are maintained and installed correctly as described in the user manual and subject to the BAUER AERO-GUARD being used if CO2 concentration in the intake air exceeds prescribed standard values.

40 l condensate collection system

40 l condensate collection system
This convenient system provides a central collection point for the condensate (oil and water mixture) produced during the compression process inside the compressor. The condensate tank features an integrated float switch which can be relied upon to monitor the level of condensate in the tank and provides protection against overfilling. A combined silencer and filter unit prevents pollution caused by noise or odour.
