1100 040 020 Single Cylinder, Air Compressor — MERCEDES BENZ

The heavy-duty single cylinder air compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to provide consistent air pressure, this unit ensures the reliability of the vehicle's braking and suspension functions. Built with high-strength components, it is engineered to withstand rigorous operational cycles in demanding environments.

1100 040 020 is the OE-equivalent of the MERCEDES BENZ 906 130 25 15 SP1 and WABCO 85000329 SP1 air compressors used in MERCEDES BENZ heavy commercial vehicles. This part is also compatible with systems requiring codes 906 130 2515 SP1, 906 130 46 15 SP1, and 906 130 4615 SP1. It maintains strict adherence to technical specifications for seamless integration into existing pneumatic architectures.

For workshop technicians, this water-cooled unit requires careful attention to the water inlet (M14x1,5) and outlet (M14x1,5) ports to ensure proper thermal regulation. The air inlet features an M26x1,5 connection and an outlet of Ø30. Regular inspection of the single cylinder assembly and the through-drive mechanism is recommended during routine heavy commercial vehicle maintenance to prevent system pressure drops.
