KZ433 Twin Cylinder Compressor for Knorr-Bremse

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles, providing the necessary compressed air through two piston-cylinder assemblies. By utilizing two compression strokes, it delivers a higher air output compared to single-cylinder units, ensuring faster reservoir filling for high-demand applications.

This specific model is engineered for heavy-duty performance, featuring a 440cm³ swept volume and a Ø75.00 mm cylinder bore. It is designed to operate within water-cooled systems to prevent overheating during sustained use in heavy-duty service. The unit includes M26x1,5 air inlet and outlet ports, along with M16x1,5 water ports for efficient thermal management.

For workshop technicians performing installation or maintenance, ensure all connections to the engine cooling circuit are secure. The through drive design and water-cooled valve plate are integrated to support long-haul and heavy-load operations. Proper inspection of the M26x1,5 ports and cooling lines is recommended during routine service intervals to prevent pressure loss.
