51541009903 Compatible MAN NÜ Air Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate high-volume compressed air. Designed for high-demand applications, this unit ensures efficient reservoir filling through its dual-cylinder architecture, providing greater output than single-cylinder alternatives. It is built with high-strength components to withstand the rigorous operating conditions of heavy-duty service.

Compatible MAN NÜ vehicles

This specific model is designed for MAN NÜ trucks, including the 360, 310, and 310 CNG variants. It functions seamlessly within the pneumatic systems of these heavy commercial vehicles to maintain consistent air pressure for braking and suspension functions. The unit's design ensures precise integration with the engine's drive system.

Installation and maintenance

Technicians should note that this is a water-cooled unit featuring M22x1.5 water inlet and outlet ports, alongside M26x1.5 air inlet and outlet ports. The assembly includes a water-cooled valve plate and a through drive configuration to ensure stable performance during intensive use. Proper installation requires verifying the water cooling lines and port connections.

System performance

Regular inspection of the cooling system and air lines is recommended to prevent pressure drops or overheating during operation.
