1700 010 004 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is an essential component of the air brake system in heavy commercial vehicles, designed to generate high-volume compressed air through two piston-cylinder assemblies. By utilizing two compression strokes per crankshaft revolution, this unit provides a higher air output compared to single-cylinder alternatives, allowing for faster reservoir filling. This makes it ideal for high-demand applications where consistent air pressure is critical for braking performance.

Vehicle and system compatibility

This specific model is compatible with Renault Trucks. It is engineered to meet the rigorous demands of heavy commercial vehicles by maintaining stable pressure even under high load. It is also compatible with Knorr-Bremse systems, providing a reliable solution for fleet maintenance and technical service requirements.

Technical specifications and installation

This water-cooled unit features a Ø78.00 mm cylinder bore and a 52 mm stroke to ensure efficient compression. The installation requires careful attention to the M26x1,5 air inlet and outlet ports, as well as the M18x1,5 water ports. Ensuring correct mounting of the through-drive gear and proper coolant flow is vital for the long-term durability of the internal components.

Maintenance and troubleshooting

Technicians should monitor the compressor for any unusual noise or drops in air pressure, which may indicate wear in the valve plate or piston rings. Regular inspection of the water cooling lines and port connections is recommended to prevent overheating or pressure leaks in the pneumatic system.
