LP4815 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty grade air compressor is a vital component in the pneumatic systems of heavy commercial vehicles. This twin cylinder unit ensures consistent air pressure delivery to support braking and suspension functions. Designed with high-strength components, it provides reliable operation within demanding industrial environments.

LP4815 is the OE-equivalent of the KNORR-BREMSE LP4815 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This unit features a 440cm³ swept volume and a Ø75.00 mm cylinder bore to meet strict performance standards. It is engineered to maintain structural integrity under high thermal and mechanical stress.

For workshop technicians, this compressor offers a precise fit with an M26x1,5 air inlet and outlet port configuration. The water-cooled design includes a water-cooled valve plate and M16x1,5 ports for optimized thermal management. Regular maintenance of the cooling lines and checking the through-drive integrity are essential for long-term service reliability.

This part is specifically designed for integration into heavy commercial vehicle braking architectures. It ensures that the air delivery remains stable during long-haul operations. Professionals should ensure the water inlet and outlet paths are clear to maintain the cooling efficiency of the two-cylinder system.
