2900 040 001 Compatible Single Cylinder Air Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a vital component in the pneumatic braking system of heavy commercial vehicles. By utilizing a single-piston design, it generates the pressurized air required for braking performance and pneumatic system operations. The unit is engineered with high-strength components to withstand continuous duty cycles within demanding environments.

Vehicle compatibility and fitment

This specific model is compatible with Volkswagen Truck engines and systems. It is designed to integrate seamlessly into the air processing unit, providing a steady flow of compressed air to the tanks. This component is essential for maintaining the safety and responsiveness of the vehicle's braking performance.

Technical specifications and installation

The assembly features a water-cooled design to manage operating temperatures effectively during heavy-duty use. Technical specifications include a Ø88.00 mm cylinder bore, a 37 mm stroke, and 1,2” - 14 UNF threading for both air and water ports. Technicians should ensure that all connections are secure and that the cooling system provides adequate flow to prevent overheating.

Maintenance and troubleshooting

Regular inspection of the piston and ring assembly is recommended to maintain optimal compression efficiency. Monitoring the air outlet pressure helps in identifying early signs of wear within the single-cylinder housing.
