3971519 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 braking system of heavy commercial vehicles. It operates by compressing intake air to provide the necessary pressure for the air processing unit and storage tanks. Built with high-strength components, this unit is engineered to maintain consistent performance under demanding operational conditions.

Engine compatibility and technical features

This specific model is designed to be compatible with Cummins ISBe, ISDe, LF45, and LF55 engines. It features a through-drive configuration and is specifically designed as a water-cooled unit to manage thermal loads during sustained engine operation. Check the compatibility list.

Installation and maintenance guidance

Technicians should verify the M26x1,5 air inlet port and M18x1,5 air outlet port during installation to ensure proper seal integrity. Given the water-cooled nature of this compressor, inspecting the M16x1,5 water inlet and outlet ports is essential to prevent overheating. Proper maintenance of the cooling circuit ensures long-term reliability.

Performance monitoring

Regular inspection of the 225cm³ swept volume performance and overall pressure output can help identify potential system leaks or wear before they impact braking performance.
