1100 045 021 Single Cylinder Air Compressor — MERCEDES BENZ

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Designed with a high-strength architecture, the unit utilizes a water-cooling system to maintain optimal operating temperatures during intense service cycles. The integration of a water-cooled valve plate ensures long-term durability and stable performance under heavy-duty conditions.

1100 045 021 is the OE-equivalent of the MERCEDES BENZ 906 130 50 15 SP2, 906 130 54 15 SP1, 906 130 58 15 SP1 and WABCO 411 151 009 0 SP1, 411 151 012 0 SP1 used in compatible heavy commercial vehicle systems. This precision component is essential for maintaining reliable air pressure for braking and pneumatic control functions.

For workshop technicians, this unit offers seamless assembly thanks to its standardized M26x1,5 air inlet and Ø30 outlet specifications. Regular inspection of the water inlet and outlet ports (M14x1,5) is recommended to ensure proper cooling flow and prevent overheating. Proper installation of the through-drive mechanism is critical for maintaining synchronized engine timing and air delivery efficiency.

The component is specifically designed for heavy-duty applications where constant air supply is vital for safety. By utilizing high-strength components and precise tolerances such as the Ø85.00 mm bore, this compressor provides the reliability required by fleet managers and professional workshops.
