Description

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. By compressing intake air, it provides the necessary pressure for the air processing unit and subsequent distribution to the air tanks. This specific model is a water-cooled unit, designed to be integrated into the engine cooling circuit to prevent overheating during sustained heavy-load operations.

Technical specifications and compatibility

The unit features a single-cylinder design with a 352cm³ swept volume, an Ø85.00 mm bore, and a 62 mm stroke. It is compatible with WABCO systems and is engineered to meet the rigorous demands of heavy commercial vehicle braking requirements. The water-cooled valve plate and through-drive configuration ensure stable performance under high-pressure conditions.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the M14x1,5 water inlet and outlet ports are securely connected to the engine cooling circuit. Regular inspection of the M26x1,5 air inlet port and Ø30 air outlet port is recommended to prevent leaks. Ensuring the water-cooled valve plate remains free of debris is essential for maintaining consistent compression efficiency.

Troubleshooting and performance

Monitoring air pressure build-up rates can help identify potential issues within the compressor or the broader pneumatic system before they impact braking performance.
