Abstract: Apparatus for removing moisture such as oil and water vapor from compressed gases such as air with less decrease in pressure by conventional filter means by providing a relatively coarse annular filter to condense the major portion of such moisture by gases passing downward therethrough to afford drainage of condensate by gravity before the gases pass upward through coaxial interior desiccant filter means to remove any residual moisture before the moisture free gases are discharged from the upper end of the desiccant filter means. The coarse filter is contained between transparent outer and inner containers and the desiccant filter means is contained within the transparent inner container so as to extend upwardly above the upper end of the coarse filter such that the condition of both the coarse filter and desiccant filter means is visually observable.
