LP 4974 KNORR-BREMSE Twin Cylinder, Air Compressor

The high-strength component is engineered to provide reliable air compression within heavy commercial vehicle pneumatic systems. This twin cylinder configuration ensures consistent pressure and operational stability under demanding service conditions. Designed for durability, the unit features a robust construction to maintain optimal performance in heavy-duty environments.

LP 4974 is the OE-equivalent twin cylinder, air compressor used in KNORR-BREMSE systems. This unit features a cylinder bore of Ø88.00 and a swept volume of 608cm³, ensuring high-capacity output. It is specifically designed to meet the technical requirements of the KNORR-BREMSE system architecture.

For workshop technicians, this air compressor offers precise fitment with an air inlet port of Ø29 and an air outlet port of M26x1,5. The water-cooled design (W) includes a water inlet and outlet with M16x1,5 threads to manage thermal loads effectively. Regular inspection of the through drive and unloader port (M22x1,5) is recommended during routine maintenance to ensure system longevity.

This component is built with heavy-duty grade materials to withstand the rigors of long-haul transport operations. The integration of a water-cooled valve plate further enhances its thermal management capabilities, making it a dependable part for professional workshop service and maintenance.
