1100 010 021 Twin Cylinder, Air Compressor — MERCEDES BENZ

This twin cylinder air compressor is engineered to provide reliable pneumatic pressure for heavy commercial vehicle braking systems. Designed with a high-strength component structure, it features a water-cooled configuration to ensure optimal thermal management during intensive operation. The integration of the ESS feature and a water-cooled valve plate ensures consistent performance under heavy-duty load conditions.

1100 010 021 is the OE equivalent of the MERCEDES BENZ 457 130 20 15 SP1, 457 130 46 15 SP1, and 457 130 66 15 SP1 air compressor used in MERCEDES BENZ and WABCO systems. This component also serves as a direct replacement for WABCO part numbers 911 553 003 0 SP1 and 911 553 007 0 SP1, ensuring precise fitment within the original braking architecture.

Workshop technicians should note the specific port dimensions for correct installation and maintenance. The unit features a Ø85.00 mm cylinder bore and a 56 mm stroke, with an air outlet port of M26x1,5 and an air unloader port of M12x1,5. Regular checks of the water inlet and outlet ports (M16x1,5) are recommended to maintain the cooling efficiency of the system during routine service intervals.
