3949098 CUMMINS ISC Single Cylinder, Air Compressor

This single cylinder air compressor is a vital component for maintaining consistent pneumatic pressure within the vehicle's braking and engine systems. Engineered with high-strength components, it features a cylinder bore of Ø85.00 and a stroke of 56 mm to ensure optimal volumetric efficiency. The water-cooled design provides superior thermal management, making it suitable for the rigorous demands of heavy commercial vehicle operations.

3949098 is the OE-equivalent of the CUMMINS 3949098 single cylinder air compressor used in the CUMMINS ISC engine series. This part meets strict technical standards to ensure seamless integration with existing engine architectures. It is designed to provide reliable performance in demanding environments where consistent air production is critical for system safety.

For workshop technicians, this unit offers straightforward installation thanks to its standardized ports, including an M27x2 air outlet and 3/4" - 16 UNF water inlet/outlet connections. The inclusion of an ESS feature and water-cooled valve plate ensures stability during extended operation. Regular inspection of the water cooling ports and air unloader port (M10x1) is recommended to maintain peak performance and prevent system downtime.

Maintenance of the air compressor system is essential for preventing pneumatic failures in heavy commercial vehicles. This component is built to withstand high temperatures and pressure fluctuations typical in heavy-duty truck and bus engine environments.
