A4571304415SP2 Compressor Twin Cylinder Equivalent

What does a twin cylinder compressor do?

This engine-driven twin cylinder compressor plays a critical role in the air brake system of heavy commercial vehicles by generating high-volume compressed air. By utilizing two piston-cylinder assemblies, this unit delivers significantly higher air output compared to single-cylinder designs, ensuring faster reservoir filling for demanding applications.

Vehicle compatibility and specifications

This specific model is designed for Mercedes-Benz applications and is compatible with heavy commercial vehicle systems requiring efficient air production. It features a water-cooled design with a water inlet and outlet port size of M16x1,5 to manage operating temperatures effectively during continuous service.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the M26x1,5 air inlet and outlet ports and ensure the water cooling lines are clear. This unit includes an ESS feature and a water-cooled valve plate to maintain optimal performance under heavy-duty conditions. Always check the mounting interface before replacement.

Troubleshooting and performance

Maintaining correct air pressure levels is vital for the safety of the braking system. If air pressure builds slowly or the compressor runs excessively, inspect the unloader port (M12x1,5) and cooling efficiency to ensure system integrity.
