1186722SP Knorr-Bremse compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher volume of compressed air compared to single-cylinder alternatives, ensuring rapid reservoir filling. This unit is engineered with high-strength components to withstand the rigorous demands of heavy-duty operation.

System compatibility and design

The assembly is specifically designed to function within Knorr-Bremse systems. It features a water-cooled design to manage thermal loads during sustained use, utilizing M16x1,5 water inlet and outlet ports. This ensures stable performance even in high-demand applications like multi-axle tractor units or heavy tipper trucks.

Installation and maintenance

Installation and maintenance should be performed by a workshop technician to ensure correct torque on the M26x1,5 air ports and proper integration into the engine cooling circuit. Regular checks of the through drive and water cooling lines are recommended to maintain optimal air pressure delivery and prevent system overheating.

Troubleshooting and selection

When replacing this unit, it is vital to ensure the mounting interface and through drive configuration match the existing setup to avoid system mismatch.
