51541009005 MAN NG Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This water-cooled twin cylinder compressor is designed to provide high-capacity air generation for heavy commercial vehicle braking systems. By utilizing two piston-cylinder assemblies, it delivers a higher air output than single-cylinder alternatives at the same engine speed, making it essential for high-demand pneumatic operations.

Compatibility and technical specifications

This specific unit is designed for use in MAN NG 230 CNG trucks. It features a Ø100.00 mm cylinder bore, a 46mm stroke, and a total swept volume of 720cm³. The assembly includes M26x1.5 air inlet and outlet ports, along with M22x1.5 water inlet and outlet ports for integrated engine cooling circuit integration.

Installation and maintenance guidance

For workshop technicians, ensuring correct installation of the water cooling lines is critical to prevent overheating during sustained heavy-load operation. This through-drive model is engineered with a water-cooled valve plate to maintain thermal stability under high pressure.

System performance and selection

When replacing this component, verify that the M26x1.5 air ports and M22x1.5 water connections match the existing vehicle configuration to ensure seamless integration into the pneumatic system.
