K000237ES Knorr-Bremse Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven component designed to provide high-capacity compressed air within the pneumatic braking systems of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, this unit delivers a significantly higher air output per revolution compared to single-cylinder alternatives, making it essential for vehicles with high air consumption requirements.

Compatibility and vehicle applications

The unit is engineered to work seamlessly with Knorr-Bremse systems and is specifically suited for heavy-duty applications such as multi-axle tractor units, touring coaches, and tipper trucks. It features a water-cooled design to maintain optimal operating temperatures during sustained heavy-load operation, ensuring long-term reliability under extreme service conditions.

Technical specifications and installation

Technical specifications include a Ø88.00 mm cylinder bore and a 50 mm stroke, providing a swept volume of 608cm³. The installation interface includes an M26x1,5 air outlet port and an M22x1,5 unloader port, alongside M16x1,5 water inlet and outlet ports. This through-drive model includes an ESS feature and a water-cooled valve plate for enhanced system stability.

Maintenance and cooling requirements

For proper maintenance, technicians should regularly inspect the water cooling circuit and connection ports to prevent leaks or overheating. Ensuring the integrity of the M16x1,5 water lines is critical for maintaining the thermal regulation of the internal components.
