3968694 Cummins Compatible ISBe Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic system of heavy commercial vehicles. It functions by compressing intake air to supply the brake system and air processing units, ensuring consistent pressure for reliable braking performance. Built with high-strength components, this unit is engineered to withstand the rigorous thermal and mechanical stresses found in demanding heavy-duty environments.

Compatible engines and fitment

This specific model is designed for compatibility with Cummins ISBe, ISDe, and ISLe engines. By maintaining precise pressure regulation through its integrated ESS feature and water-cooled valve plate, it ensures stable operation for the engine's air demand. This compressor is an essential part for maintaining the integrity of the entire pneumatic circuit in heavy-duty applications.

Technical specifications and installation

The unit features a water-cooled design to prevent overheating during sustained operation, utilizing M16x1.5 water inlet and outlet ports. Technical specifications include a Ø80.00 mm cylinder bore, a 45mm stroke, and a 225cm³ swept volume. For proper installation, ensure the M26x1.5 air inlet and M22x1.5 air outlet connections are correctly torqued to prevent leaks.

Maintenance and troubleshooting

Regular inspection of the water cooling circuit and air ports is recommended to prevent system pressure drops. If air production decreases or temperature rises unexpectedly, check the valve plate and cooling lines to ensure optimal functionality.
