1100 020 004 MERCEDES BENZ Twin Cylinder, Air Compressor

The twin cylinder air compressor is a critical component in the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure for braking and auxiliary functions. This high-strength component features a dual-cylinder design with a swept volume of 636cm³ and is specifically engineered for water-cooled operation to maintain optimal thermal stability during intensive duty cycles.

1100 020 004 is the OE equivalent of the MERCEDES BENZ 457 130 19 15 and WABCO 911 553 101 0 air compressors used in heavy-duty truck systems. This part ensures seamless integration with compatible MERCEDES BENZ and WABCO hardware, maintaining the high standards required for heavy commercial vehicle pneumatic systems.

Workshop technicians should ensure that the water inlet and outlet ports (M16x1,5) are correctly connected to the cooling circuit to prevent overheating. The installation process requires precise alignment of the M26x1,5 air ports and checking the M12x1,5 unloader port functionality. Regular maintenance of the water-cooled valve plate and monitoring the ESS feature performance is recommended to ensure long-term reliability in the field.

This air compressor is designed to withstand extreme operating conditions, providing reliable air delivery for various heavy-duty applications. Its robust construction supports high-demand environments typical of professional transport services.
