Abstract
An apparatus and method for filtering a fluid stream wherein the fluid stream is passed through a first filtering zone to remove particulate materials therefrom above a first preselected micron level, then through a desiccant media bed zone including a multiplicity of desiccant beads to dry the fluid stream and then through a second filtering zone to remove particulate materials therefrom above a second preselected micron level below said first micron level so as to remove smaller particulate materials including particulates from said first filtering zone.
