This single cylinder air compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for the braking system. Built with high-strength components, this unit is engineered to withstand intense operating conditions while maintaining consistent air pressure delivery for safety-critical functions.

This compressor is designed to be compatible with Cummins engines and their associated pneumatic systems. It features a water-cooled configuration with a 56 mm stroke and an Ø85.00 mm cylinder bore, ensuring efficient thermal management during continuous operation in heavy-duty applications.

For proper installation and maintenance, technicians should verify the connection of the 3/4" - 16 UNF water inlet and outlet ports to ensure adequate cooling. Regular inspection of the M27x2 air outlet port and the M10x1 unloader port is recommended to prevent leaks and maintain optimal system pressure.
