K000237ES SP1 Knorr-Bremse Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical engine-driven component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate compressed air. By producing two compression strokes per crankshaft revolution, this unit delivers significantly higher air output than single-cylinder alternatives, ensuring pneumatic reservoirs are filled rapidly even under high demand.

Compatibility and technical specifications

This specific model is designed for heavy-duty performance and is compatible with Knorr-Bremse systems. It features a water-cooled design with an Ø88.00 mm cylinder bore and a 50 mm stroke, resulting in a swept volume of 608cm³. The unit is equipped with an M26x1,5 air outlet port and an M22x1,5 unloader port to ensure precise system regulation.

Installation and maintenance guidance

For workshop technicians, proper installation is vital to maintain system integrity. This unit includes a water-cooled valve plate and is designed for through-drive applications. When replacing the unit, ensure that the water inlet and outlet ports (M16x1,5) and the gear drive interface align perfectly with the existing engine mounting to prevent leaks or mechanical misalignment.

Operational reliability

Regular inspection of the air inlet port (Ø29) and the water cooling lines is recommended to prevent contamination or overheating within the pneumatic circuit.
