4937720 CUMMINS Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component within the engine system, providing the necessary pneumatic pressure for heavy commercial vehicle operations. Engineered with a focus on durability, it features a water-cooled design to maintain optimal thermal stability during continuous operation. The unit is built to handle high-stress environments, ensuring a consistent air supply for braking and auxiliary systems.

4937720 is the OE-equivalent of the CUMMINS 4937720 Single Cylinder, Air Compressor used in the CUMMINS ISB engine series. This component is engineered to meet strict industrial standards, ensuring seamless integration with existing engine architectures. It features a specific configuration including an M26x1.5 air inlet port and an M22x1.5 air outlet port to maintain system integrity.

For workshop technicians and fleet managers, this compressor offers straightforward installation and long-term reliability. The unit includes a through-drive design and an integrated ESS feature to optimize performance. Maintenance should focus on ensuring the water inlet (M16x1.5) and outlet (M16x1.5) ports are clear and that all connections are secured to prevent pressure drops in the pneumatic circuit.

Technical specifications include a 225cm³ swept volume and an M10x1 air unloader port. The water-cooled architecture makes it highly suitable for long-haul heavy commercial vehicle applications where thermal management is vital for preventing component fatigue.
