1100 255 002 Twin Cylinder Air Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor functions as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher volume of compressed air compared to single-cylinder units, ensuring rapid reservoir filling. This high-output capability is essential for maintaining consistent air pressure in demanding braking applications.

Vehicle compatibility and features

This specific unit is compatible with Mercedes-Benz vehicles. It is engineered to meet the rigorous requirements of heavy commercial duty cycles, featuring a water-cooled design to manage thermal loads effectively during continuous operation. The assembly includes integrated features like the ESS feature and a water-cooled valve plate to ensure long-term reliability.

Technical specifications and installation

Technical specifications for this component include an Ø85.00 mm cylinder bore and a 56 mm stroke, resulting in a 636cm³ swept volume. The unit is equipped with M26x1,5 air inlet and outlet ports, an M12x1,5 unloader port, and M16x1,5 water ports. Installation should be performed by a workshop technician to ensure correct mounting and connection of the cooling lines.

Maintenance and system health

Regular inspection of the air and water ports is recommended to prevent leaks or blockages that could impact braking performance. Maintaining clean cooling fluid levels is also vital for the longevity of the water-cooled valve plate and overall system integrity.
