K155389N00 KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air compression within heavy commercial vehicle pneumatic systems. As a critical part of the air brake compressor assembly, it ensures consistent pressure levels through its robust twin-cylinder architecture. The design focuses on durability and precision to meet the rigorous demands of heavy-duty transport environments.

K155389N00 is the OE-equivalent of the KNORR-BREMSE K155389N00 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This product features a Ø86.00 mm cylinder bore and a 62 mm stroke to deliver a 720cm³ swept volume. The unit is specifically designed to be compatible with heavy-duty hardware requirements, ensuring seamless integration with existing pneumatic components.

For workshop technicians, this unit offers straightforward installation with specialized ports including an M26x1,5 air inlet and an M22x1,5 air outlet. The water-cooled (W) design utilizes M18x1,5 ports for both inlet and outlet to maintain optimal operating temperatures. Regular inspection of the M10x1 air unloader port and water cooling lines is recommended during scheduled maintenance to ensure peak performance and system longevity.

This assembly is built for heavy commercial vehicle service environments where reliability is paramount. The integration of a water-cooled valve plate and ESS feature enhances the component's ability to handle high-load cycles without compromising pressure stability.
