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 of heavy commercial vehicles. By utilizing a piston-driven mechanism, it compresses intake air to provide the necessary pressure for the air processing unit and storage tanks. This specific model is engineered with a water-cooling system to maintain optimal operating temperatures during continuous service, ensuring long-term reliability under heavy-duty conditions.

Compatibility and technical design

This component is compatible with Cummins systems and is designed to meet strict industrial standards for performance. It features a through-drive design and includes an ESS feature for enhanced system control. The unit is built with high-strength components to withstand the high-pressure requirements of heavy commercial vehicle braking networks.

Installation and maintenance guidance

For optimal performance, technicians should verify the water inlet and outlet ports, which utilize 3/4" - 16 UNF connections. Regular inspection of the M10x1 unloader port and the Ø25 air inlet should be part of routine maintenance to prevent pressure drops. Proper installation ensures the integrity of the entire pneumatic circuit.

System reliability

Consult your authorized distributor for more information on fitment and installation.
