LK4918 KNORR-BREMSE Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent air pressure within the pneumatic braking system of heavy commercial vehicles. Designed with a robust structure, it serves as a critical component for maintaining operational safety and system reliability during long-haul transport operations.

LK4918 is the OE-equivalent of the KNORR-BREMSE LK4918 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This high-strength component features a Ø88.00 cylinder bore and a 50 mm stroke, ensuring precise volumetric performance. The assembly is specifically designed for water-cooled applications to manage thermal loads effectively during high-demand service intervals.

Workshop technicians should ensure that the water inlet and outlet ports (M16x1,5) are properly connected to the cooling circuit to prevent overheating. The unit includes an ESS feature and a specialized M26x1,5 air outlet port to maintain seamless integration with existing heavy-duty pneumatic hardware. Regular inspection of the unloader port and seals is recommended to ensure peak performance.
