1200 040 002 MAN Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-driven mechanism, it generates the compressed air required for brake actuation and system pressure maintenance. Built with high-strength components, this water-cooled unit is designed to withstand the rigorous thermal demands of continuous operation in heavy-duty environments.

Compatible MAN vehicles and engines

This compressor is specifically engineered for compatibility with various MAN models, including the TGM I series (such as the 18.240 and 26.330), TGL I (fitted with D0834 engines), LION´S CITY A 37, and TGA variants. It functions as a reliable replacement for original equipment in these specific heavy commercial vehicle applications.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the water inlet and outlet connections at the M14x1,5 ports to ensure leak-free integration with the engine cooling circuit. Maintaining clean coolant flow is essential for managing the thermal load during high-pressure cycles. Check the compatibility list for specific fitment details.

Troubleshooting and service tips

Regular inspection of the through drive mechanism and port integrity helps prevent system pressure drops. Ensuring the air inlet and outlet ports remain free of contaminants is vital for extending the service life of the internal piston assembly.
