Abstract:

A filter element designed for engine oil lubrication and hydraulic oils, comprising a core having a hollow interior and a perforated outer surface, in fluid communication with the hollow interior, an open first end in fluid communication with the hollow interior, and a closed second end. The filter element comprises alternately wrapping one or more layers of flat sheet barrier filter material and, on top of the barrier filter material, winding, in a uniform winding pattern, one or more layers of cotton/cellulose composition yarn over the outer surface of the core, each layer having a progressively finer filtration as the oil moves radially from the exterior of the element inward towards the core.
