1100 250 003 Twin Cylinder Air Compressor — MERCEDES BENZ

This heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure for demanding heavy commercial vehicle systems. Featuring a robust dual-cylinder design and a specialized water-cooled valve plate, it ensures optimal thermal management during high-load operations. The component is built with high-strength components to maintain performance under extreme industrial conditions.

1100 250 003 is the OE equivalent of the MERCEDES BENZ 457 130 37 15 air compressor used in the MERCEDES BENZ AXOR, AXOR 2, and CITARO O530 series with OM457 engines. This unit is also compatible with WABCO systems (912 510 101 0). It is designed specifically for heavy commercial vehicle applications such as the AXOR 2 2443 and various heavy-duty truck models to ensure seamless integration with existing engine architectures.

For workshop technicians, this air compressor features a through-drive design and an integrated ESS feature for enhanced control. The installation requires precise alignment of the M26x1,5 inlet and outlet ports along with the M16x1,5 water ports to ensure efficient cooling and pressure stability. Regular inspection of the water-cooled components and port seals is recommended during routine maintenance to prevent system leaks.

Proper maintenance of the air compressor system is vital for the overall pneumatic reliability of the vehicle. Technicians should verify the integrity of the M12x1,5 unloader port and ensure that the water cooling flow remains unobstructed to prevent overheating of the valve plate during long-distance transport operations.
