LP 4974 SP1 KNORR-BREMSE Twin Cylinder Air Compressor

This water-cooled twin cylinder air compressor is engineered to provide consistent pneumatic pressure within heavy commercial vehicle braking systems. By utilizing high-strength components and a robust dual-cylinder design, it ensures reliable performance under demanding industrial operating conditions. The unit is specifically designed to maintain system integrity through efficient thermal management via its water-cooling interface.

LP 4974 SP1 is the OE-equivalent KNORR-BREMSE Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This precision-engineered component features a cylinder bore of Ø88.00 mm and a swept volume of 608cm³, ensuring it meets the rigorous demands of heavy commercial vehicle air brake architectures. It is fully compatible with the technical requirements of high-pressure pneumatic systems.

For workshop technicians and fleet managers, this compressor offers a seamless installation process with standardized port sizes including an M26x1,5 air outlet and M22x1,5 unloader port. The inclusion of an ESS feature and a water-cooled valve plate provides additional durability during long-haul operations. Regular maintenance and checking the water inlet (M16x1,5) and outlet ports is recommended to ensure optimal cooling efficiency and system longevity.

Maintaining the air brake system requires components that can withstand high thermal loads. This twin cylinder model is built to handle the complexities of modern heavy-duty transport, providing stable air supply for braking and suspension functions without degradation in performance.
