1100 020 020 Twin Cylinder, Air Compressor — WABCO

The heavy-duty Twin Cylinder, Air Compressor provides essential pneumatic pressure for heavy commercial vehicle systems. Designed with a Ø85.0s Bore and a 56 mm Stroke, this component is engineered to maintain consistent performance under demanding operating conditions. The inclusion of a water-cooled system ensures optimal thermal management during continuous operation.

1100 020 020 is the OE-equivalent of the MERCEDES BENZ A4571302415 SP1 and WABCO 412 352 027 0 air compressor used in MERCEDES BENZ, KENWORTH, MERITOR, PACCAR, and PETERBILT systems. This part is precision-engineered to meet the strict technical requirements of modern heavy-duty braking and pneumatic architectures.

For workshop technicians, this unit features an M26x1,5 air inlet/outlet port and an M12x1,5 air unloader port. The assembly includes an ESS feature and a water-cooled valve plate to enhance system longevity. Proper installation should follow standard heavy vehicle service protocols to ensure seamless integration with the existing air brake compressor-driven systems.

Maintaining the correct service intervals and ensuring the water-cooling ports (M16x1,5) are clear will prevent premature wear in the cylinder system. This component is specifically designed for professional service environments focusing on high-reliability pneumatic output.
