The Quanchai W962 Oil Filter is engineered for reliable performance in demanding diesel and industrial applications. It provides filtration down to 10–15 microns, effectively removing metal particles, sludge, and contaminants to maintain clean oil flow and reduce engine wear.
Equipped with a built-in bypass valve (2.5 bar), the filter ensures continuous lubrication even under high pressure or restricted flow conditions, protecting critical components from damage.
This model is widely compatible with Quanchai QC490 and QC498 engines, and is commonly used in forklifts, tractors, trucks, and screw air compressors. Its spin-on design allows for quick installation and secure sealing, simplifying maintenance operations.
Built for heavy-duty use, it offers durability and consistent performance in industrial and agricultural environments, helping to extend equipment lifespan and maintain optimal efficiency.
