1100 250 002 Mercedes-Benz Compatible Twin Cylinder Compressor

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 the compressed air required for braking and pneumatic functions. By utilizing two piston-cylinder assemblies, this unit delivers higher air output than single-cylinder alternatives, making it ideal for high-demand applications. It is built with high-strength components to withstand the rigors of heavy-duty service cycles.

Compatibility and engine fitment

This unit is compatible with Mercedes-Benz vehicles and is designed to meet stringent industrial standards. The assembly features a 636cm³ swept volume and includes integrated ESS features for enhanced reliability. It is also suitable for various heavy commercial vehicle configurations that require consistent air pressure maintenance.

Installation and maintenance guidance

Installation requires careful attention to the water inlet and outlet ports, which utilize M16x1,5 threads, alongside the M26x1,5 air inlet and outlet ports. Technicians should verify the M12x1,5 unloader port configuration during assembly to ensure proper system regulation. Regular checks of the water cooling lines and mounting interface are recommended to maintain optimal performance.

System performance and selection

For optimal system longevity, ensure that the water cooling flow is unobstructed and that all connections are torqued to specification. This compressor is a reliable replacement for units requiring high air volume delivery in demanding transport environments.
