1400 090 012 KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air pressure for heavy commercial vehicle braking systems. As a critical part of the pneumatic system, this twin cylinder air compressor ensures consistent performance under demanding operating conditions. The robust design is optimized for long-term durability and high-pressure stability.

The 1400 090 012 is the OE equivalent of the KNORR-BREMSE K009581, K009581000, LK4951 and SCANIA 1767161 used in heavy-duty vehicles. This specific model is designed for compatibility with KNORR-BREMSE and SCANIA systems. It features a cylinder bore of Ø86.00 and a stroke of 62 mm to meet precise engineering requirements.

Technicians should note the specific port configurations during installation to ensure proper integration. The unit features an M26x1,5 air inlet port, an M22x1,5 air outlet port, and an M10x1 air unloader port. It is a water-cooled (W) system with M18x1,5 water inlet and outlet ports to maintain optimal operating temperatures.

Regular inspection of the water cooling ports and the connection integrity of the M26x1,5 inlet is recommended to prevent system downtime. Always verify that the through-drive and ESS features are correctly aligned with the existing vehicle hardware before completing the assembly.
