Description

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven unit in the air brake system of heavy commercial vehicles that generates compressed air using two piston-cylinder assemblies. It is designed to deliver higher air output than single-cylinder types, ensuring faster reservoir filling for high-demand applications.

Technical specifications and cooling

The unit is engineered for durability in heavy commercial vehicle systems. It features a 440cm³ swept volume, a Ø75.00 mm cylinder bore, and a 50 mm stroke. For optimal thermal regulation during sustained operation, this model utilizes a water-cooling system with M18x1,5 inlet and outlet ports.

Installation and maintenance guidance

Maintenance technicians should ensure the water cooling circuit is clear and the M12x1,5 air unloader port remains free of debris to maintain pressure stability. This component is compatible with Knorr-Bremse systems and is built with high-strength components to withstand heavy-duty service cycles.

System integration

When replacing this unit, verify that the through drive and mounting interfaces match the existing engine setup to ensure seamless integration into the pneumatic circuit.

OE cross-reference

1400 040 002 (Twin Cylinder Compressor) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number 1189106.
