51541007178 Compatible Twin Cylinder Compressor — MAN SÜ

What does a twin cylinder compressor do?

This water-cooled twin cylinder compressor is designed to provide high-capacity air generation for the pneumatic systems of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, this unit ensures a higher air output compared to single-cylinder alternatives, making it essential for maintaining consistent air pressure in demanding braking applications.

Compatible MAN SÜ vehicle fitment

This specific model is compatible with MAN SÜ series vehicles, including the SÜ 263, SÜ 313, and SÜ 363 variants. It is engineered to meet the rigorous requirements of heavy-duty operation, ensuring the air brake system receives a steady supply of compressed air even under high load conditions.

Technical specifications and installation

The unit features a 720cm³ swept volume and a Ø100.00mm cylinder bore with a 46mm stroke. For installation and maintenance, technicians should ensure the water inlet and outlet ports (M22x1,5) are correctly integrated into the engine cooling circuit and that the M26x1,5 air ports are properly secured to prevent leaks.

Maintenance and system reliability

Regular checks of the water-cooled valve plate and connection points are recommended to ensure optimal performance. Maintaining the cooling circuit integrity is vital for preventing overheating during sustained heavy-duty use in long-haul or construction applications.
