2900 030 001 CUMMINS Single Cylinder, Air Compressor

This high-strength component serves as a critical element within the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking operations. Designed for durability, it manages high-pressure air compression through a single-cylinder mechanism optimized for stability and long-term performance in demanding environments.

The 2900 030 001 is the OE equivalent of the CUMMINS 3965888 and CUMMINS 4937720 air compressor used in ATLAS COPCO, CUMMINS, KNORR-BREMSE, and VOLKSWAGEN TRUCK systems. This single cylinder unit features a water-cooled design with specific port dimensions including an M26x1,5 air inlet and an M22x1,5 air outlet to meet precise engineering requirements.

For workshop technicians, this part is engineered with a through-drive capability and includes an ESS feature for enhanced operational reliability. Maintenance should focus on inspecting the water inlet and outlet ports (M16x1,5) and ensuring the unloader port remains unobstructed to maintain optimal system pressure. Regular checks of the water-cooling interface are recommended to prevent overheating during intensive operation.

The assembly is specifically designed to integrate seamlessly into existing heavy-duty engine configurations. By maintaining compatibility with standard OEM specifications, it ensures that the pneumatic supply remains stable even under heavy workloads.
