2800 040 001 Mack Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This water-cooled single cylinder air compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. It functions by compressing intake air and delivering it to the air processing unit to maintain stable pressure within the braking circuit. Engineered with high-strength components, this unit is designed to withstand the rigorous thermal demands of heavy-duty operation.

Compatible Mack vehicles and engines

This compressor is compatible with several Mack models including the Anthem, Granite, LR, MRU, Pinnacle, Terrapro, and Titan. It is specifically designed to work with Mack MP7, MP8, and MP10 engines. The unit ensures reliable performance across these heavy commercial vehicle applications.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify that the water inlet and outlet ports (M16x1,5) are correctly integrated into the engine cooling circuit. Given the water-cooled design, ensuring consistent coolant flow is essential to prevent overheating during sustained heavy-load operation. The M26x1,5 outlet port should be inspected for secure connections to prevent pressure loss.

Troubleshooting and maintenance

Maintaining the air unloader port (M12x1,5) and checking the through drive mechanism will help prevent premature wear of internal components.
