412 352 001 0 SP1 Single Cylinder Air Brake Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor functions as a vital component within the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-driven mechanism, it compresses intake air and directs it to the air processing unit and storage tanks to maintain necessary system pressure. This specific model is designed with water-cooling capabilities to manage thermal loads during continuous operation.

Compatible vehicles and engine fitment

This component is compatible with Mercedes-Benz vehicles. It features a single-piston, single-cylinder housing structure designed for durability in heavy-duty environments. The unit includes an ESS feature and a water-cooled valve plate to enhance thermal management and efficiency during high-pressure cycles.

Installation and maintenance guidance

For proper installation, technicians should ensure all port connections are secure, specifically the M26x1,5 air ports and the M16x1,5 water inlet/outlet ports. Given the 15.9 KG weight and water-cooled design, ensure the cooling lines are free of obstructions to prevent overheating. Regular inspection of the M12x1,5 unloader port is recommended to maintain optimal pressure regulation.

Troubleshooting and maintenance tips

Maintaining consistent air pressure is critical for brake performance in heavy commercial vehicles. If air pressure builds slowly or leakage is detected at the ports, professional inspection of the internal piston assembly and valve plate is advised to restore system integrity.
