3949098 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake 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 and storage tanks. Built with high-strength components, this water-cooled unit is designed to maintain stable pressure even under demanding thermal loads encountered during continuous operation.

Compatibility and technical features

This specific model is compatible with Cummins systems and is engineered to meet strict industrial requirements. It features a through-drive design and includes an integrated ESS feature for optimized performance. The unit utilizes a water-cooled valve plate to ensure long-term durability in heavy-duty environments.

Installation and maintenance guidance

For proper installation, technicians should verify the M27x2 outlet port and the 3/4" - 16 UNF water inlet and outlet connections. Given its 19.5 KG weight and specialized port sizes, ensuring correct alignment with the engine drive is vital for preventing premature wear on the piston assembly.

Troubleshooting and system performance

Regular inspection of the air unloader port and cooling lines is recommended to maintain optimal air delivery and prevent system pressure drops.
