1100 020 004 WABCO Compatible Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is a vital component designed to maintain consistent pneumatic pressure within the vehicle's braking and suspension systems. Engineered with high-strength components, this unit ensures reliable operation under demanding heavy commercial vehicle service conditions. The integration of a water-cooled valve plate enhances thermal management during high-load cycles.

1100 020 004 is the OE-equivalent of the WABCO 911 553 101 0 air compressor used in heavy commercial vehicle systems. This component is specifically developed to meet the rigorous requirements of professional workshop technicians and fleet managers who demand precision and durability. It features a specialized Ø85.00 mm cylinder bore and a dual-cylinder configuration to provide stable air output.

For the workshop technician, installation requires careful attention to the M26x1,5 air ports and the M16x1,5 water inlet/outlet ports to prevent leaks. The unit includes an ESS feature and is designed for water-cooled applications to ensure optimal temperature regulation during operation. Regular inspection of the air unloader port (M12x1,5) and cooling connections is recommended to maintain peak system performance.

This air compressor is engineered for seamless integration into existing pneumatic architectures, providing a reliable source of compressed air for essential vehicle functions. Its robust construction helps prevent system pressure drops and ensures long-term operational stability in heavy-duty environments.
