470 130 38 15 Mercedes-Benz AROC S OM 470 LA Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates the necessary air pressure required for reliable braking performance and system operation under demanding conditions. The unit is engineered with high-strength components to withstand continuous service cycles in professional transport environments.

Compatible Mercedes-Benz AROCS models

This specific model is compatible with Mercedes-Benz AROCS trucks (1836 A and 1836 AK variants) equipped with the OM 470 LA engine. It features a water-cooled design with a swept volume of 490cm³ and is optimized for Euro 6 emission standards. The unit includes an ESS feature and a water-cooled valve plate to maintain optimal operating temperatures during heavy-duty use.

Installation and maintenance guidance

For proper installation, technicians should verify that the water inlet and outlet ports (M18x1,5) and the air outlet port (M26x1,5) align with the existing vehicle connections. Ensuring the through drive mechanism and mounting interface match the original equipment is essential for successful replacement. Regular inspection of the cooling lines and air intake is recommended to extend service life.

Operational reliability

Maintaining consistent air pressure depends on the integrity of all pneumatic components. When replacing this unit, ensure that all mounting surfaces are clean and that the cooling system is free of obstructions to prevent overheating during operation.
