51541009903 Twin Cylinder Compressor for MAN SG

What does a twin cylinder compressor do?

This water-cooled twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, generating high-volume compressed air through two piston-cylinder assemblies. By utilizing two cylinders, this unit provides a significantly higher air output compared to single-cylinder alternatives, making it ideal for heavy-duty applications that require rapid air reservoir replenishment.

Compatibility and technical specifications

This specific model is designed for use in MAN SG 260 and 310 vehicles. It features a through-drive design and is engineered to operate within the engine's cooling circuit via M22x1,5 water inlet and outlet ports to maintain optimal thermal stability during sustained operation.

Installation and maintenance guidance

For professional installation, technicians should verify the M26x1,5 air inlet and outlet port connections. This unit includes a water-cooled valve plate to ensure efficient heat dissipation. Given the 32.2 KG weight and high-strength components, ensure secure mounting to the engine block following manufacturer torque specifications.

Operational reliability

Maintaining proper coolant flow through the M22x1,5 ports is essential to prevent overheating. Regular inspection of the air ports and water connections will help ensure long-term reliability in high-demand service environments.
