3949098 CUMMINS ISL Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component for maintaining consistent pneumatic pressure within the heavy commercial vehicle system. Engineered with heavy-duty grade materials, it provides stable air output essential for engine performance and braking-related systems. The design focuses on durability and high-strength component integrity to withstand rigorous industrial operating conditions.

3949098 is the OE-equivalent of the CUMMINS 3949098 single cylinder air compressor used in the CUMMINS ISL engine systems. This part ensures seamless integration and maintains the required swept volume of 318cm³ for optimal air delivery. It is specifically designed to meet the exacting standards required by the CUMMINS ISL series.

For workshop technicians, this part offers straightforward installation with a through-drive configuration and specialized water-cooled ports (3/4" - 16 UNF). The integration of the ESS feature and precise M27x2 outlet ensures reliable pressure regulation. Regular maintenance of the water cooling circuit and checking the M10x1 unloader port connections are recommended to ensure long-term serviceability.

Technical precision is maintained through the Ø85.00 cylinder bore and the specific displacement requirements of the ISL engine platform. This ensures that the air compressor functions at peak efficiency within the pneumatic circuit of the heavy commercial vehicle.
