3948846 Compatible ISB6.7 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 compressing intake air and directing it to the air processing unit, it ensures the necessary pressure is maintained for reliable braking performance. The unit is engineered with high-strength components to withstand the rigorous thermal and mechanical stresses of continuous operation.

Engine compatibility and cooling

This specific model is compatible with Cummins engines and various heavy commercial vehicle applications. It features a water-cooled design to manage operating temperatures efficiently during long-haul or heavy-load operations, ensuring consistent air delivery to the tanks.

Installation and maintenance guidance

Maintenance of this compressor requires careful inspection of the water inlet and outlet ports, which utilize 3/4" - 16 UNF connections. Technicians should verify the integrity of the M27x2 air outlet port and the M10x1 unloader port during routine service intervals to prevent pressure drops or leaks in the pneumatic circuit.

System performance and reliability

Regularly checking the through-drive mechanism and cooling flow helps prevent premature wear of the internal piston assembly. For optimal system longevity, ensure all connections are secure and that the cooling circuit remains free of obstructions.

OE cross-reference

2500 030 002 (Single Cylinder Compressor) is the equivalent of the Cummins OE number. This part directly replaces Cummins OE number 3948846.
