This twin cylinder air compressor is a critical component for maintaining consistent pneumatic pressure within the vehicle's braking and suspension systems. Engineered with a robust structure, it features a cylinder bore of Ø85.00 mm and a stroke of 56 mm, providing a swept volume of 636cm³. The unit is designed for water-cooled operation to ensure stable thermal management during intensive heavy commercial vehicle operations.

1100 255 020 is the OE equivalent of the MERCEDES BENZ 457 130 69 15 SP1 and WABCO 912 510 200 0 SP1 used in heavy commercial vehicle systems. This high-strength component is specifically designed for compatibility with Mercedes Benz and WABCO hardware architectures. Its precision-engineered ports, including M26x1,5 air inlet/outlet and M16x1,5 water ports, ensure a perfect fit within the original system architecture.

Workshop technicians should note that this model is a water-cooled (W) type and includes an ESS feature with a water-cooled valve plate for enhanced reliability. When performing maintenance or replacement, ensure the M12x1,5 air unloader port and the M26x1,5 pneumatic connections are checked for integrity. Proper installation of this twin cylinder unit is essential for the optimal performance of the vehicle's air brake system.
