2500 280 001 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty grade twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the braking system of heavy commercial vehicles. It features a robust construction with a Ø86.00 cylinder bore and a 460cm³ swept volume to ensure reliable operation under demanding thermal conditions. The unit is designed for water-cooled (W) applications, utilizing M16x1,5 water inlet and outlet ports to maintain optimal operating temperatures.

2500 280 001 is the OE-equivalent of the CUMMINS 5339231 and KNORR-BREMSE K068756N10, K068756N11, and LK4984 air compressors used in CUMMINS B6.7 and ISB6.7 engine systems. This component ensures seamless integration with existing pneumatic architectures, maintaining the high standards required for heavy commercial vehicle braking performance.

For workshop technicians, this unit offers straightforward installation through its specialized M26x1,5 air inlet and outlet ports. Regular maintenance of the water cooling circuit and checking the connection integrity of the through-drive system is recommended to ensure long-term service life. Proper synchronization with the engine's timing and cooling system is essential for optimal air compressor efficiency in heavy-duty truck environments.
