3968696 Cummins ISLe Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic system of heavy commercial vehicles. By converting mechanical energy into compressed air, it provides the necessary pressure for the entire braking system to function reliably. This component is manufactured using high-strength components to ensure durability under continuous operating conditions.

Engine compatibility and fitment

Designed specifically for compatibility with Cummins engines, including the ISLe, ISDe, and ISBe series, this unit ensures precise air delivery. The design incorporates a water-cooled configuration to maintain optimal operating temperatures during heavy-duty cycles. It is an essential part for maintaining the integrity of the air brake system in large-scale transport applications.

Technical specifications and installation

This unit features a 3/4”-14 NPT air inlet and outlet port, alongside a 1/2”-14 NPT water inlet and outlet port. With a swept volume of 318cm³ and an 85.00 mm cylinder bore, it provides stable performance. Technicians should ensure that the water cooling lines are clear and that all ports are tightened to prevent pressure loss or leaks during installation.

Maintenance and troubleshooting

Regular inspection of the piston movement and cooling flow is recommended to prevent system failures. Maintaining clean air intake through the 3/4”-14 NPT inlet helps prolong the service life of the internal components.
