3949718 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system, providing the necessary compressed air for heavy commercial vehicle operations. It utilizes a high-strength single-piston design to ensure consistent pressure delivery to the air processing unit and tanks.

Compatibility and technical specifications

This component is designed for compatibility with Cummins systems. It is built to withstand high-temperature environments, featuring a water-cooled valve plate and specific water inlet/outlet ports (3/4 - 16 UNF) to manage thermal loads effectively during continuous operation.

Installation and maintenance guidance

For proper installation, technicians should verify the air outlet port (M27x2) and unloader port (M10x1) connections. Maintaining clean air intake via the Ø25 inlet port is essential to prevent premature wear of the internal components and ensure long-term service life.

Troubleshooting and system checks

Regular inspection of the through-drive mechanism and cooling lines is recommended to prevent pressure drops in the braking circuit. Consult your authorized distributor for fitment verification.
