3971519 Single Cylinder Compressor for ISBe Engines

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 single-piston design, it compresses intake air to provide the necessary pressure for the air processing unit and storage tanks. The unit is engineered with heavy-duty grade materials to withstand high-pressure cycles and sustained thermal loads during operation.

Engine compatibility and application

This specific model is compatible with Cummins engines, including the ISBe, ISDe, LF45, and LF55 series. It is designed to integrate seamlessly into the engine's cooling circuit through its water-cooled architecture, ensuring stable performance under heavy load conditions. This compressor is essential for maintaining consistent air pressure in braking systems for trucks and construction machinery.

Installation and technical specifications

Technicians should note the specific technical parameters during installation: this unit features an M26x1.5 air inlet port and M18x1.5 air outlet port, along with M16x1.5 ports for water circulation. The through-drive configuration and 225cm³ swept volume are critical for calculating system capacity. Regular inspection of the water inlet and outlet connections is recommended to prevent overheating.

Maintenance guidance

Consult your authorized distributor for fitment verification.
