LK3904 KNORR-BREMSE Single Cylinder, Air Compressor

The single cylinder air compressor is a vital component for maintaining consistent air pressure within the pneumatic braking systems of heavy commercial vehicles. This water-cooled unit is engineered with high-strength components to ensure reliable operation under demanding industrial conditions. Its robust design supports the continuous air production required for heavy-duty vehicle stability and safety.

LK3904 is the OE-equivalent of the KNORR-BREMSE LK3904 Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part is specifically designed to meet the rigorous standards of the heavy commercial vehicle sector, ensuring seamless integration with compatible pneumatic architectures. It serves as a direct replacement to maintain original system performance and pressure regulation.

For workshop technicians and fleet managers, this unit offers precise fitment with an air inlet port of M26x1,5 and a water inlet port of M22x1,5. Proper installation requires attention to the water cooling connections to ensure optimal thermal management during operation. Regular inspection of the water inlet and outlet ports is recommended to prevent any buildup that could affect the cooling efficiency of the compressor system.
