kz4331rm KNORR-BREMSE Twin Cylinder Air Compressor

This high-strength twin cylinder air compressor is engineered to provide consistent air pressure for heavy commercial vehicle braking systems. Designed for reliability in demanding environments, the unit utilizes a robust two-cylinder configuration to ensure stable pneumatic performance during operation.

This kz4331rm is the OE-equivalent of the KNORR-BREMSE KZ433\1RM twin cylinder air compressor used in VOLVO systems. It serves as a direct replacement for several high-demand references including 1186722SP, KZ433, KZ433\1X50, 1080437, 1186722, 1188844, 1570594, 1590264, and 1612335. The unit is specifically designed to match the technical requirements of both KNORR-BREMSE and VOLVO heavy commercial vehicle architectures.

Designed for professional workshop technicians, this component features a water-cooled system with an M16x1,5 water inlet and outlet for optimal thermal management. The assembly includes a through-drive mechanism and an integrated ESS feature to maintain system integrity. Regular maintenance of the cooling lines and checking the M26x1,5 air ports ensures the long-term durability of the compressor within the pneumatic circuit.

The installation of this component requires precision to ensure the gear interface and cooling connections are perfectly aligned. Proper lubrication and monitoring of the water cooling efficiency are essential for preventing overheating in high-duty cycles.
