1100 020 003 MERCEDES BENZ Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air compression for heavy commercial vehicle braking systems. As a twin cylinder unit, it ensures consistent pressure delivery under demanding operating conditions through its optimized design and robust construction.

The 1100 020 003 is the OE equivalent of the MERCEDES BENZ 457132215 and WABCO 9115531030 used in compatible heavy-duty vehicles. This unit features a water-cooled system with a water-cooled valve plate to maintain thermal stability. It is specifically designed for compatibility with MERCEDES BENZ systems and WABCO hardware.

The technical specifications include a cylinder bore of Ø85.00 and a stroke of 56 mm, producing a swept volume of 636cm³. The assembly features M26x1,5 ports for both air inlet and outlet, alongside M16x1,5 ports for water management to ensure precise pneumatic and thermal regulation during service.

When performing maintenance or replacement, technicians should verify the compatibility of the water inlet and outlet ports to ensure seamless integration with the existing cooling circuit. Check the through-drive and ESS feature functionality during installation to maintain optimal system performance.
