Useful Information

Description and Purpose:

This Air Compressor from Cummins, identified by Part number: 5286961, is a new genuine component engineered for ISB and QSB engines meeting EPA07 standards. Its water-cooled, single-cylinder design supports continuous air pressure generation for critical pneumatic functions.

Restored air pressure output enhances braking confidence, improves pneumatic responsiveness, and contributes to overall operational reliability.

Cummins® combines precision manufacturing with rigorous testing to deliver components that maintain smooth engine function and consistent performance.
