KZ642 KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength twin cylinder air compressor is engineered to provide reliable pneumatic pressure for heavy commercial vehicle braking systems. Designed with a focus on durability, it ensures consistent performance under demanding operating conditions through its advanced water-cooling architecture and robust construction.

The KZ642 is the OE equivalent of the KNORR-BREMSE KZ642 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This component features a 75.00 mm cylinder bore and a 50 mm stroke, providing a swept volume of 440cm³. It is specifically designed for integration with high-standard pneumatic braking circuits.

Technicians should ensure the water inlet and outlet ports (M18x1,5) are properly connected to maintain optimal cooling efficiency. The inclusion of an ESS feature and a water-cooled valve plate provides additional protection against thermal stress during operation. Regular inspection of the M12x1,5 air unloader port is recommended to maintain system integrity.

This component is essential for maintaining the pneumatic air supply required for stable braking performance. Its precision engineering supports the rigorous demands of heavy commercial vehicle maintenance and fleet service.
