k001389lk3863 Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By compressing intake air and delivering it to the air processing unit, it ensures the necessary pressure is maintained for reliable braking performance. This water-cooled unit is engineered to operate under demanding conditions by utilizing the engine's cooling circuit to prevent overheating during sustained use.

Compatibility and technical specifications

This specific model is designed for compatibility with Knorr-Bremse systems. It features a 225cm³ swept volume, a Ø80.00 cylinder bore, and a 45mm stroke. The design includes an M26x1,5 air inlet port, an M22x1,5 outlet port, and an M10x1 unloader port, ensuring precise integration into existing pneumatic architectures.

Installation and maintenance guidance

For workshop technicians, maintaining proper coolant flow through the M16x1,5 water ports is essential to prevent thermal stress. When inspecting the unit, check the through drive mechanism and the valve plate integrity to ensure consistent air output. Regular checks of the air inlet and outlet connections help prevent leaks that could compromise braking efficiency.

System reliability and selection

Selecting the correct compressor is vital for maintaining system pressure within specified limits. This unit provides a robust solution for applications requiring stable air generation through high-strength components.
