Description

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic braking system, providing the necessary compressed air for heavy commercial vehicle operation. By utilizing a single-piston design, it ensures efficient air production for systems with specific demand requirements while maintaining a compact footprint for easier integration.

Technical specifications and compatibility

Designed for durability, this water-cooled unit is integrated into the engine cooling circuit to prevent overheating during sustained heavy-duty operation. It features a Ø85.00 mm cylinder bore and a 62 mm stroke, delivering a swept volume of 352cm³. This component is compatible with WABCO systems and is engineered to meet rigorous service demands.

Installation and maintenance guidance

Installation requires careful attention to the water inlet and outlet ports, which utilize M14x1,5 threads to ensure secure connections within the cooling circuit. Technicians should verify the air inlet port (M26x1,5) and air outlet port (Ø30) specifications during assembly to ensure optimal performance and prevent system leaks.

Operational reliability

To maintain peak efficiency, regular inspection of the water-cooled valve plate and connection points is recommended to avoid pressure drops in the pneumatic circuit.
