411 151 012 0 SP1 Single Cylinder Compressor Compatible with WABCO

What does a single cylinder compressor do?

This single cylinder air compressor is a vital component of the pneumatic braking system, responsible for generating the compressed air required for reliable braking performance. It functions by compressing intake air and delivering it to the air processing unit through an Ø30 outlet port. This specific model is designed for heavy-duty operation, utilizing a water-cooling system to maintain optimal thermal stability during continuous use.

Compatible vehicles and system fitment

This compressor is compatible with WABCO systems and is engineered to meet strict industrial requirements. It features a single-cylinder design with a 238cm³ swept volume, ensuring efficient air production for vehicles requiring steady pneumatic pressure. The unit is built with high-strength components, including a water-cooled valve plate and M26x1,5 air inlet port, to withstand high-pressure environments.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify that the water inlet and outlet ports (M14x1,5) are correctly integrated into the engine cooling circuit. Regular inspection of the single piston and ring assemblies is recommended to prevent pressure drops. Ensuring clean coolant flow through the water ports is essential for preventing overheating during long-haul operations.

Troubleshooting and selection

When troubleshooting air pressure issues, check the integrity of the M26x1,5 inlet and Ø30 outlet connections first. A failure in this component can directly impact the overall responsiveness of the vehicle's braking system.
