LP4934 KNORR-BREMSE Twin Cylinder, Air Compressor

The technical performance of the air braking system relies on high-precision components. This twin cylinder air compressor is engineered to provide consistent air pressure through a robust two-cylinder design, ensuring the reliability of the pneumatic system in heavy commercial vehicles. The assembly features a water-cooled valve plate and optimized port dimensions to maintain thermal stability during operation.

LP4934 is the OE-equivalent of the KNORR-BREMSE Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This part is designed for heavy commercial vehicle applications where high-strength components are required to meet strict operational demands. It features a cylinder bore of Ø88.00 mm and a stroke of 50 mm, providing a swept volume of 608cm³ for efficient air production.

For workshop technicians and fleet managers, this compressor offers seamless integration with existing pneumatic circuits. The unit includes an M26x1,5 air outlet port and an M22x1,5 air unloader port to ensure precise pressure regulation. Maintenance should focus on checking the water inlet and outlet ports (M16x1,5) to ensure optimal cooling performance and prevent overheating during long-haul operations.

This component is built with high-strength components to withstand the rigorous environments of heavy duty transport. The inclusion of an ESS feature and a specialized water-cooled valve plate ensures that the compressor maintains peak efficiency even under high thermal loads.
