51541007003 Twin Cylinder Compressor for MAN

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 air brake systems. By utilizing two piston-cylinder assemblies, this unit ensures a higher air output compared to single-cylinder alternatives, making it essential for vehicles requiring rapid pressure buildup and consistent performance under heavy loads.

Vehicle and engine compatibility

This component is compatible with MAN SÜ series trucks, specifically designed for models such as the SÜ 263, SÜ 313, 363, and 313. It functions as a critical part of the pneumatic braking system, ensuring that the air reservoir maintains sufficient pressure for safe vehicle operation across various heavy-duty applications.

Technical specifications and design

The unit features a through-drive design and a water-cooled valve plate to manage thermal loads effectively during sustained operation. Technical specifications include a Ø100.00 mm cylinder bore, a 46mm stroke, and M26x1.5 air inlet and outlet ports. The water circuit utilizes M22x1.5 ports to integrate seamlessly into the engine cooling system.

Maintenance and installation guidance

To ensure optimal performance, technicians should inspect the water inlet and outlet connections regularly to prevent leaks or cooling inefficiencies. Proper maintenance of the cooling circuit is vital to prevent overheating of the valve plate and maintain the integrity of the internal components.
