3968694 Single Cylinder Compressor for Cummins Engines

What does a single cylinder compressor do?

This single cylinder air compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing the compressed air required for brake performance and air-operated systems. Built with high-strength components, it ensures consistent pressure delivery even under demanding operating conditions through its robust internal structure.

Engine compatibility and fitment

This specific unit is engineered to be compatible with Cummins engines, specifically the ISBe, ISDe, and ISLe series. Its design focuses on efficient air generation and reliable integration within the engine's cooling circuit to maintain optimal operating temperatures during sustained use.

Technical specifications

Technical specifications include a Ø80.00 mm cylinder bore and a 45mm stroke, providing a swept volume of 225cm³. The unit features an M26x1.5 air inlet port, an M22x1.5 air outlet port, and an M12x1.5 air unloader port. As a water-cooled model, it utilizes M16x1.5 water inlet and outlet ports to facilitate thermal management.

Maintenance and inspection

To ensure proper function, technicians should regularly inspect the water cooling lines and check the integrity of the M22x1.5 outlet connection. Maintaining clean air intake through the M26x1.5 inlet is essential for preventing premature wear within the cylinder assembly.
