K004640 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within heavy commercial vehicle air brake systems. Designed for high-reliability environments, the component utilizes heavy-duty grade materials to ensure long-term operational stability in demanding industrial applications.

K004640 is the OE-equivalent of the KNORR-BREMSE K004640 single cylinder air compressor used in heavy commercial vehicle systems. This unit is fully compatible with KNORR-BREMSE hardware requirements, ensuring seamless integration with existing pneumatic architectures.

The assembly features a single cylinder design with a 45 mm stroke and a swept volume of 225cm³. The unit is water-cooled (W) to manage thermal loads during continuous operation, utilizing M16x1,5 ports for both water inlet and outlet. Workshop technicians should ensure the M26x1,5 inlet and M18x1,5 outlet connections are properly sealed to maintain system pressure integrity.

Maintaining proper cooling and checking the through-drive functionality is essential for the longevity of the compressor. This part provides a precise fit for professional workshop service and fleet maintenance where high-strength components are required for air brake system reliability.
