Cummins maintenance filters serve as the "first line of defense" for engine health, including three categories: air filters, fuel filters, and oil filters. They deeply purify the intake, fuel, and lubrication systems respectively, intercepting dust, particles, colloids, and other impurities to avoid wear of precision engine components and extend overhaul intervals, compatible with all Cummins series such as ISX, QSB, and NT855.
Air filters use multi-layer composite filter materials with 99.9% filtration efficiency (for 0.3μm particles) to ensure clean intake air; fuel filters integrate water separation function, intercepting over 99.6% of impurities above 5μm to protect injectors and high-pressure pumps; oil filters adopt glass fiber filter paper with a dirt-holding capacity of over 25g to prevent sludge from blocking lubrication channels. All three types use temperature and oil-resistant materials, with an operating temperature range of -30℃ to 120℃, adapting to different working conditions.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. offers two options: Original filters strictly follow Cummins ISO/TS 16949 standards, with each batch tested for flow and filtration efficiency, suitable for heavy-duty equipment requiring high maintenance precision; Aftermarket filters, verified by third-party performance tests, with key indicators reaching over 90% of the original, priced at 50%-60% of the original, suitable for regular maintenance and budget control, both providing 12-month warranty.
It is recommended to replace regularly according to Cummins maintenance manual (air filters every 1500 hours, fuel/oil filters every 2000 hours), ensuring tight sealing during installation. We stock 80% of common models, supporting global delivery within 48 hours, and our technical team can provide compatibility inquiries.
