Description

This twin cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy commercial vehicle air brake systems. Designed with a robust structure, the component ensures consistent performance under demanding operational conditions through its high-strength components and precision-engineered cylinder architecture.

K009403 is the OE-equivalent of the KNORR-BREMSE K009403 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This part is specifically designed for high-duty cycles and maintains strict compatibility with original technical requirements for the heavy commercial vehicle sector.

The assembly features a Ø92.00 cylinder bore and a 54 mm stroke to achieve a 720cm³ swept volume. It is a water-cooled unit featuring an M18x1,5 water inlet and outlet configuration, alongside an M10x1 air unloader port. The integrated ESS feature and water-cooled valve plate ensure thermal stability during operation.

Workshop technicians should verify the water inlet/outlet connections and the Ø36.50 air inlet port during installation to ensure optimal cooling and pressure-building efficiency. Regular inspection of the unloader port and seal integrity is recommended to maintain system reliability in heavy commercial vehicle fleets.
