1100 255 021 Twin Cylinder Air Compressor MERCEDES BENZ

The heavy-duty grade air compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed for high-pressure stability, this twin cylinder unit ensures consistent air delivery to maintain optimal braking performance. The construction focuses on high-strength components to withstand rigorous operational cycles in demanding transport environments.

1100 255 021 is the OE-equivalent of the MERCEDES BENZ 457 130 55 15 SP1 and WABCO 912 510 201 0 SP1 air compressors used in heavy commercial vehicle systems. This part is engineered for precise compatibility with MERCEDES BENZ and WABCO hardware, ensuring seamless integration with existing engine-driven pneumatic circuits. It serves as a reliable replacement for original equipment specifications.

Workshop technicians should note that this unit features a water-cooled design, utilizing M16x1,5 ports for both water inlet and outlet to manage thermal loads effectively. The assembly includes an M26x1,5 air inlet and outlet port configuration. Regular inspection of the water cooling lines and the unloader port (M12x1,5) is recommended during scheduled service intervals to prevent system overheating or pressure drops.

Maintenance of the air compressor system is vital for heavy-duty vehicle safety. Ensuring the through-drive and ESS feature function correctly will help extend the service life of the entire pneumatic assembly and prevent unexpected downtime in fleet operations.
