1100 255 003 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder air compressor is an essential engine-driven component within the pneumatic braking system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, this unit generates compressed air more efficiently than single-cylinder alternatives, ensuring rapid reservoir replenishment for high-demand applications. It is constructed from high-strength components to withstand rigorous operational cycles.

Technical specifications and compatibility

This specific unit is designed to be compatible with WABCO systems. It features a swept volume of 636cm³, a cylinder diameter of Ø85.00 mm, and a 56 mm stroke. The configuration includes a water-cooled valve plate and through drive capability to manage thermal loads during intensive use.

Installation and maintenance guidance

When performing maintenance or installation, technicians should verify the M26x1.5 air ports and the M12x1.5 air unloader port to ensure airtight seals. Since this is a water-cooled model, checking the M16x1.5 water inlet and outlet connections is vital for preventing overheating during operation.

Operational checks

For optimal performance, ensure the unloader port remains free of debris and check the cooling lines regularly to maintain consistent air pressure delivery.
