1100 120 003 MERCEDES BENZ Single Cylinder, Air Compressor

The high-strength components of this single cylinder air compressor ensure consistent air pressure delivery for heavy commercial vehicle pneumatic systems. Designed for durability, this part plays a vital role in the engine assembly by providing regulated air flow through a robust water-cooled mechanism. It is engineered to withstand the rigorous thermal and mechanical stresses typical of long-haul transport operations.

This 1100 120 003 is the OE-equivalent of the MERCEDES BENZ 447 130 37 15 and 447 130 05 15 single cylinder air compressors used in MERCEDES BENZ heavy-duty vehicles. The unit features a specialized water-cooled valve plate and precise M26x1,5 threading for both inlet and outlet ports to ensure a secure, leak-free connection within the air brake system.

For workshop technicians performing routine maintenance or engine overhauls, this component offers seamless integration with existing cooling lines. The through-drive design and specific port dimensions (M22x1,5 for water ports) allow for precise installation. Regular inspection of the water inlet and outlet seals is recommended to maintain optimal thermal regulation and prevent system downtime during service intervals.
