Abstract

A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear.
