1400 040 002 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure for essential braking and suspension systems. Designed with a robust structure, this component features a Ø75.00 cylinder bore and a 50 mm stroke to maintain high efficiency during operation. The water-cooled design ensures thermal stability, making it an essential part for long-haul heavy commercial vehicle applications.

This specific unit serves as the OE-equivalent for the KNORR-BREMSE 1189106, KZ642, KZ642/2RM, and KZ642/2X50 systems, as well as SCANIA parts 10571185, 1300366, 1348919, and 394441. It is built to meet strict industrial standards for compatibility with SCANIA and KNORR-BREMSE heavy commercial vehicle architectures. The integration of the ESS feature and a water-cooled valve plate ensures the unit maintains performance under high-load conditions.

For workshop technicians performing maintenance or system overhauls, this compressor provides a precise fitment with M18x1,5 water ports and an M12x1,5 air unloader port. Ensuring correct installation of the water-cooled components is vital for preventing overheating in the air brake system. Regular inspections of the through-drive and port seals are recommended during routine service intervals to maintain optimal pneumatic output.
