K009403 KNORR-BREMSE Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy commercial vehicle braking systems. Designed with a focus on high-strength components, it ensures consistent air production through its robust construction and optimized internal geometry. The unit features a Ø92.00 mm cylinder bore and a 54 mm stroke to meet demanding service requirements.

K009403 is the OE-equivalent of the KNORR-BREMSE K009403 twin cylinder air compressor used in KNORR-BREMSE systems. This component is specifically engineered for professional workshop technicians and fleet managers who require precise compatibility with original equipment standards. It maintains strict adherence to the technical specifications required for heavy-duty air brake compressor operations.

The assembly is designed for water-cooled applications, featuring an M18x1,5 water inlet and outlet port configuration to manage thermal loads effectively during operation. With an air unloader port of M10x1 and a 720cm³ swept volume, it provides stable performance in high-utilization environments. Maintenance teams should ensure all connections, including the Ø36.50 air inlet and Ø16.30 outlet ports, are secured according to standard heavy commercial vehicle service protocols to maintain optimal system pressure.
