1916521 C9 Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to provide the essential compressed air required for braking systems in heavy commercial vehicles. It functions by taking drive from the engine to compress intake air, which is then sent to the air processing unit and reservoirs. This unit is critical for maintaining pneumatic pressure throughout the vehicle's braking circuit.

Engine compatibility and fitment

This specific model is compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 series. It is engineered to operate within high-demand environments, ensuring consistent air pressure delivery for heavy commercial vehicle applications.

Technical specifications and cooling

The unit features a water-cooled design to prevent overheating during sustained operation, making it ideal for long-haul or heavy-load tasks. Key technical specifications include a 54 mm stroke, a 360cm³ swept volume, and an air inlet port of 7/8’’-14 UNF. It also includes an integrated ESS feature and a water-cooled valve plate to enhance thermal management and durability.

Maintenance and installation guidance

To ensure optimal performance, technicians should inspect the water inlet and outlet ports (3/4’’-16 UNF) regularly to prevent blockages in the cooling circuit. Maintaining proper lubrication and checking the unloader port (1/8’’-27 NPT) will help extend the service life of this high-strength component.
