2900 070 001 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle braking and suspension systems. Designed with a robust structure, it utilizes high-strength components to withstand intense operational cycles within the engine system.

2900 070 001 is the OE-equivalent of the CUMMINS 4933229 and KNORR-BREMSE K011246 air compressors used in various heavy-duty vehicle applications. This part is specifically developed to maintain optimal performance and compatibility with original equipment standards for CUMMINS and KNORR-BREMSE systems.

The technical specifications include a Ø80.00 cylinder bore, a 45mm stroke, and a 225cm³ swept volume. The unit features an M26x1,5 air inlet port, an M22x1,5 air outlet port, and an M10x1 air unloader port. It is a water-cooled (W) system with M16x1,5 ports for both water inlet and outlet, ensuring efficient thermal management during continuous operation.

Workshop technicians should ensure proper installation of the water cooling lines and verify the M26x1,5 and M22x1,5 port connections to prevent leaks. Regular maintenance of the water-cooled valve plate and monitoring the through-drive system will help extend the service life of the compressor within the vehicle's pneumatic circuit.
