A8845034370SP1 Single Cylinder Air Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component in the pneumatic braking system of heavy commercial vehicles. It functions by compressing intake air and delivering it to the air processing unit, which subsequently distributes it to the air tanks to maintain necessary system pressure. Built with high-strength components, this unit is designed to withstand rigorous operating conditions while ensuring consistent performance.

Vehicle and engine compatibility

This specific model is compatible with Mercedes-Benz trucks and buses. It features a water-cooled design to prevent overheating during extended operation, making it suitable for heavy-duty duty cycles. The unit includes an ESS feature and a water-cooled valve plate for enhanced thermal management and efficiency.

Installation and maintenance guidance

When performing installation or maintenance, technicians should verify the M26x1,5 air inlet and outlet ports as well as the M16x1,5 water inlet and outlet ports. Ensuring correct torque on these connections is critical for preventing leaks. Given the 15.9 KG weight and the through-drive configuration, secure mounting is essential for minimizing vibration during engine operation.

Troubleshooting and maintenance tips

Regular inspection of the air unloader port (M12x1,5) and checking for any signs of coolant or oil contamination in the air lines can help prevent premature wear of the internal piston and ring assemblies.
