3965888 Compatible ISBe Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor functions as a critical component within the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-driven mechanism, it converts mechanical energy into compressed air required for the air processing unit and brake tanks. This specific model is engineered with water-cooling capabilities to ensure stable performance during sustained heavy-duty operation.

Engine compatibility and fitment

This component is compatible with Cummins engines, specifically the ISBe, ISDe, and ISLe series. It is designed to integrate seamlessly into the engine's cooling circuit via the M16x1.5 water inlet and outlet ports to prevent overheating during high-pressure cycles.

Installation and technical specifications

Technical specifications include a 225cm³ swept volume and an air inlet port of M26x1.5. For installation and maintenance, technicians should verify the through drive connection and inspect the M10x1 air unloader port to ensure optimal pressure regulation. The unit features a water-cooled valve plate to enhance thermal stability.

Maintenance and troubleshooting

Monitoring air output and pressure stability is essential for maintaining braking safety. If air production decreases or pressure levels fluctuate, inspecting the water cooling lines and the unloader valve is recommended to ensure system integrity.
