1200 040 003 MAN Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system, providing the necessary compressed air for braking performance. It functions by compressing intake air and delivering it to the air processing unit, making it an essential link in the heavy commercial vehicle brake system. This unit is built with high-strength components to ensure durability under constant pressure cycles.

Vehicle and engine compatibility

This compressor is specifically compatible with MAN trucks and is also suitable for other heavy commercial vehicle applications. It operates effectively within the engine's drive system to maintain consistent air tank pressure. The design ensures seamless integration with existing pneumatic architectures found in large-scale transport fleets.

Installation and maintenance

Installation requires careful attention to the M26x1,5 air ports and M14x1,5 water ports to prevent leaks. Technicians should verify that the water-cooled valve plate is properly seated and that all connections are secure to maintain optimal thermal management during operation.

Troubleshooting and service

Regular inspection of the piston movement and port integrity can prevent sudden loss of air pressure. Maintaining clean air intake is vital for extending the service life of this single-cylinder component.
