906 130 46 15 SP1 Single Cylinder Air Brake Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By utilizing an engine-driven piston mechanism, it compresses intake air and directs it to the air processing unit and storage tanks, ensuring consistent pressure for braking operations.

Vehicle compatibility and technical specs

Designed for compatibility with Mercedes-Benz vehicles, this unit features a water-cooled design to manage thermal loads effectively during continuous operation. Key technical specifications include a Ø85.00 mm cylinder bore, a 62 mm stroke, and an air inlet port of M26x1,5, alongside an air outlet port of Ø30. This configuration provides the necessary swept volume of 352cm³ required for stable system performance.

Installation and maintenance guidance

For professional installation, technicians should verify the water inlet and outlet ports, which are M14x1,5 on this model. Ensuring correct mounting and connection of the water cooling lines is essential to maintain the thermal stability of the internal valve plate and prevent overheating during heavy-duty cycles.

System performance and selection

Regular inspection of the air intake and cooling connections can prevent pressure drops within the braking system. Check the compatibility list to ensure this component matches your specific vehicle requirements.
