k013739lk4958 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the air brake system of heavy commercial vehicles, providing the necessary compressed air through two piston-cylinder assemblies. Its design ensures a higher air output compared to single-cylinder units, making it ideal for vehicles requiring rapid reservoir recharging. Built with high-strength components, this unit is engineered to withstand the rigorous thermal and pressure demands of heavy-duty operation.

Vehicle and system compatibility

This specific model is designed to be compatible with Knorr-Bremse systems. It is suitable for heavy commercial vehicle applications that demand high air capacity, such as multi-axle tractor units or heavy-duty trucks. The unit features a water-cooled design to maintain optimal operating temperatures during sustained use.

Technical specifications and installation

Technicians should note the technical specifications during installation: this unit features a Ø86.00 bore, a 54 mm stroke, and a 630cm³ swept volume. The connections include M26x1,5 air inlet and outlet ports, M18x1,5 water ports, and an M12x1,5 unloader port. Always verify the mounting interface and cooling requirements before replacement.

Maintenance and troubleshooting

Regular inspection of the water cooling circuit and air lines is recommended to prevent system pressure drops or overheating. Ensure all ports are cleaned and seals are properly seated to maintain peak pneumatic performance throughout the service interval.
