1100 420 002 KNORR-BREMSE Twin Cylinder, Air Compressor

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure for critical vehicle systems. Designed with a robust structure, it features a cylinder bore of Ø86.00 and a stroke of 56 mm to maintain high efficiency during operation. The integrated water-cooling system and water-cooled valve plate ensure thermal stability under demanding heavy commercial vehicle service conditions.

1100 420 002 is the OE-equivalent of the KNORR-BREMSE K173359N50 twin cylinder air compressor used in MERCEDES BENZ systems. This component is also fully compatible with K173359N00 and LK2006 specifications. The assembly ensures precise integration into existing air brake architectures, providing reliable performance for fleet managers and workshop technicians who require strict OEM-standard compatibility.

For workshop technicians performing maintenance or repairs, this unit features an M26x1,5 air outlet port and Ø34.50 air inlet port for secure connections. The water inlet and outlet ports utilize M18x1,5 threads to facilitate efficient cooling. Regular inspection of the through-drive components and water cooling connections is recommended to ensure long-term system integrity within the pneumatic circuit.
