kz4331x50 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the braking system of heavy commercial vehicles. Designed with high-strength components, it ensures reliable air production and long-term operational stability under demanding workshop conditions.

KZ4331X50 is the OE-equivalent KNORR-BREMSE twin cylinder air compressor used in KNORR-BREMSE systems. This component features a cylinder bore of Ø75.00 and a 50 mm stroke to maintain optimal swept volume performance. It is specifically designed for heavy commercial vehicle applications where precision and durability are critical.

The assembly features a water-cooled design with M16x1,5 ports for both water inlet and outlet to manage thermal loads effectively. Workshop technicians should ensure the M26x1,5 air inlet and outlet connections are properly seated to prevent pressure leaks during service intervals. The integration of the ESS feature and water-cooled valve plate enhances the overall reliability of the pneumatic system.

Maintenance of the air compressor system requires regular checks of the water cooling connections and port integrity. Given its robust construction, this part is suitable for professional workshop environments focusing on heavy vehicle maintenance and repair.
