1100 255 001 MERCEDES BENZ Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air pressure within the pneumatic braking system of heavy commercial vehicles. As a twin cylinder air compressor, it ensures consistent performance and durability under demanding operating conditions.

The 1100 255 001 is the OE equivalent of the MERCEDES BENZ 4571306915 and WABCO 9125102000 air compressor used in MERC MERCEDES BENZ and SETRA vehicles. This part is specifically designed for compatibility with high-capacity engines such as the OM 457 HLA and OM 457 LA series. It meets the rigorous demands of heavy-duty service in models like the Mercedes Benz AXOR, TRAVEGO, and CITARO.

Technical specifications include a cylinder bore of Ø85.00 and a stroke of 56 mm, providing a swept volume of 636cm³. The unit features an M26x1,5 air inlet and outlet port, alongside a water-cooling system with M16x1,5 ports to manage thermal loads effectively during operation.

For workshop technicians and fleet managers, ensuring precise installation of the water-cooled valve plate and checking the M12x1,5 unloader port is essential for optimal system integration. Maintaining regular inspection intervals helps preserve the longevity of the air brake system.
