3949718 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic braking system, providing the necessary compressed air required for safe vehicle operation. Built with high-strength components, it is engineered to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle engines. By compressing intake air and delivering it to the air processing unit, it maintains the pressure levels necessary for effective braking performance.

Engine compatibility and technical features

This specific model is designed to be compatible with Cummins engines and systems. It features a water-cooled design to manage operating temperatures effectively, utilizing 3/4" - 16 UNF water inlet and outlet ports. The unit includes an ESS feature and a water-cooled valve plate to enhance durability during continuous service.

Installation and maintenance guidance

For professional installation, technicians should verify the M27x2 air outlet port and M10x1 air unloader port specifications. Ensuring correct alignment of the through-drive mechanism is essential for preventing premature wear. Regular inspection of the Ø25 air inlet port and cooling lines is recommended to maintain optimal system pressure.

Troubleshooting and replacement

A failure in this compressor can directly impact the braking response of the vehicle. When replacing, ensure the new unit matches the swept volume of 318cm³ to maintain system equilibrium.
