4980796 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor functions as a critical component within the pneumatic system of heavy commercial vehicles. By utilizing a piston-type mechanism, it compresses intake air to supply the necessary pressure for the air processing unit and storage tanks. Built with high-strength components, this unit ensures consistent air generation for braking and pneumatic functions.

Engine compatibility and fitment

This specific model is designed to be compatible with Cummins engines, including the ISBe, ISDe, and ISLe series. It features a water-cooled design to maintain optimal operating temperatures during sustained heavy-duty use, ensuring stability under high-load conditions.

Technical specifications and installation

Technicians should note the technical specifications: a Ø80.00 bore, 45mm stroke, and a 225cm³ swept volume. The unit includes an M26x1.5 air inlet port and an M22x1.5 outlet port, along with an M10x1 unloader port. Proper installation requires verifying the water circuit connections via the M16x1.5 ports to prevent overheating.

Maintenance and troubleshooting

Regular inspection of the water-cooled valve plate and unloader mechanism is recommended to prevent pressure fluctuations in the braking system.
