1189106 KNORR-BREMSE Twin Cylinder, Air Compressor

This high-strength twin cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle braking systems. It features a robust water-cooled design to ensure optimal thermal management during intensive operation. The component is designed with high-strength components to maintain performance under demanding conditions.

The 1189106 is the OE equivalent of the KNORR-BREMSE 1189106 twin cylinder, air compressor used in KNORR-BREMSE systems. This part features a Ø75.00 mm cylinder bore and a 50 mm stroke, delivering a 440cm³ swept volume. It is specifically designed for compatibility with KNORR-BREMSE hardware and high-duty pneumatic systems.

Technical specifications include an M12x1,5 air unloader port and M18x1,5 water inlet/outlet ports. The unit supports a through-drive configuration and includes the ESS feature for advanced system integration. Maintenance technicians should verify all port connections and water cooling paths during installation to ensure the integrity of the pneumatic circuit.

When replacing this component, ensure that the current system configuration matches the M18x1,5 water port specifications to prevent overheating or pressure fluctuations in the brake system.
