K055985X00 KNORR-BREMSE Twin Cylinder, Air Compressor

The technical function of this twin cylinder air compressor is to provide consistent pneumatic pressure within the vehicle's air brake system. Designed with a water-cooled architecture and a robust 720cm³ swept volume, this component ensures reliable operation under demanding heavy commercial vehicle service conditions.

K055985X00 is the OE-equivalent of the KNORR-BREMSE K055985X00 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This unit features a dual-cylinder design with a Ø92.00 mm bore and a 54 mm stroke to maintain optimal pressure levels. The precise engineering of the air inlet and outlet ports ensures seamless integration into existing pneumatic circuits.

Workshop technicians should note that this compressor is water-cooled (W), utilizing M18x1,5 ports for both inlet and outlet to manage thermal loads effectively. When performing installation or maintenance, ensure the through-drive and ESS features are correctly aligned with the vehicle's engine mounting setup. Regular checks of the water cooling lines and the M10x1 air unloader port are recommended to prevent system overheating or pressure fluctuations.

This component is specifically engineered to meet high-strength requirements for heavy commercial vehicle applications. By maintaining strict adherence to technical specifications such as the Ø36.50 air inlet port and high-strength components, it provides a stable air supply for braking and pneumatic control systems.
