1100 020 004 MERCEDES BENZ Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles. Designed to provide consistent air pressure, this part features a dual-cylinder configuration with a swept volume of 636cm³ and a Ø85.00 mm bore. The integrated water-cooled design and ESS feature ensure stable operation under demanding thermal conditions, making it a reliable choice for long-term service.

1100 020 004 is the OE equivalent of the MERCEDES BENZ 457 130 19 15 Twin Cylinder, Air Compressor used in MERCEDES BENZ systems. This component is also fully compatible with WABCO 911 553 101 0 hardware. It is engineered to meet the rigorous standards of heavy-duty vehicle braking and pneumatic systems, ensuring seamless integration with existing engine and air brake architectures.

For workshop technicians, this unit offers ease of assembly with standardized port sizes including M26x1,5 for air inlet/outlet and M16x1,5 for water ports. Regular maintenance of the water-cooling lines and monitoring the air unloader port (M12x1,5) is recommended to ensure optimal performance. This part is specifically designed for heavy commercial vehicle applications where high-strength components are required to maintain system integrity.

Proper installation and checking the water-cooled valve plate functionality during scheduled service intervals will help prevent pressure drops in the pneumatic system. The robust construction supports the high-pressure demands typical of heavy-duty transport environments.
