85000396 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. It functions by compressing intake air and distributing it to the air processing unit, ensuring the necessary pressure for reliable braking performance. This specific model is designed with a water-cooled mechanism to maintain optimal operating temperatures during heavy-duty service cycles.

Compatible vehicles and engine fitment

This component is compatible with Mercedes-Benz vehicles. The design incorporates a through drive configuration and high-strength components to withstand the rigorous demands of commercial transport environments. The unit features a Ø85.00 cylinder bore and a 62 mm stroke, providing a swept volume of 352cm³ for consistent air output.

Installation and maintenance guidance

When replacing this unit, technicians should verify the water inlet and outlet port requirements, which are M14x1,5 on this model. Ensuring that the M26x1,5 air inlet port and Ø30 outlet port connections are properly seated will prevent leaks in the pneumatic circuit. Regular inspection of the water cooling lines is recommended to maintain efficient heat dissipation.
