906 130 50 15 SP1 Mercedes-Benz Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By converting engine power into pressurized air, it provides the necessary volume required for brake actuation and system stability. The unit is engineered using high-strength components to ensure reliable performance under high-pressure cycles.

Compatibility and technical specifications

This specific model is compatible with Mercedes-Benz vehicles. It features a water-cooled design to manage thermal loads effectively during continuous operation. The technical configuration includes an Ø85.00 mm cylinder bore, a 42 mm stroke, and a swept volume of 238cm³. It is equipped with an M26x1,5 air inlet port and an Ø30 air outlet port to ensure proper integration into the existing pneumatic circuit.

Installation and maintenance guidance

For professional installation, technicians should verify the water inlet and outlet port connections (M14x1,5) and ensure the through-drive mechanism aligns with the engine configuration. Maintaining clean coolant flow and checking the valve plate integrity during service intervals will help preserve the compressor's volumetric efficiency and prevent premature wear.

System maintenance tips

Regular inspection of the air intake and cooling lines is recommended to prevent contamination within the system. Ensuring correct torque on all M14x1,5 ports prevents pressure leaks that could compromise brake performance in heavy-duty environments.
