A4721301115 Mercedes-Benz Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. It functions by compressing intake air and delivering it to the air processing unit, ensuring consistent pressure for the braking system. Built with heavy-duty grade materials, this unit is designed to withstand high thermal loads during continuous operation.

Compatibility and technical features

This specific model is designed for use in Mercedes-Benz vehicles. The assembly features a water-cooled configuration to prevent overheating during heavy-duty cycles, maintaining optimal pressure delivery. It includes an ESS feature and a water-cooled valve plate to enhance reliability under demanding conditions.

Installation and maintenance guidance

The unit is characterized by a Ø92.00 mm cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. For installation, note the M26x1,5 air outlet port and M18x1,5 water inlet/outlet ports. Ensuring correct torque on the M10x1 unloader port is essential for proper system regulation during service.

System performance and troubleshooting

Regular inspection of the water cooling lines and air inlet ports is recommended to prevent pressure drops or overheating issues in the vehicle's pneumatic circuit.
