51541007102 MAN NG Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven component essential for the air brake system of heavy commercial vehicles, providing high-volume air generation through two piston-cylinder assemblies. Designed for demanding service environments, it utilizes water cooling to maintain optimal operating temperatures during sustained high-load operation.

Vehicle compatibility and engine fitment

This specific unit is compatible with MAN NG 230 CNG engines and related heavy commercial vehicle applications. It is engineered to meet the high air demand requirements of large-scale transport vehicles, ensuring consistent pressure within the pneumatic braking circuit.

Technical specifications and installation

The assembly features a Ø100.00 mm cylinder bore and a 46mm stroke to achieve a swept volume of 720cm³. Technical installation requires connection to the engine cooling circuit via the M22x1,5 water inlet and outlet ports, while the air side utilizes M26x1,5 ports. The through drive configuration ensures stable mechanical coupling.

Maintenance and troubleshooting

Regular inspection of the water-cooled valve plate and port connections is recommended to prevent pressure drops. For correct fitment and performance, consult your authorized distributor.
