A refrigerant drier constructed to maintain compression of a desiccant to reduce the formation of refrigerant contaminating dust caused by attrition of the desiccant when the drier is used in applications subject to vibration. The desiccant is maintained in compression by a compression spring and barbed spring follower. Composite laminated filters are disposed adjacent to each end of the desiccant, with each composite filter including a fiberglass filter pad, which has excellent filtration characteristics for preventing any attrition dust which is generated from leaving either end of the drier. Each composite filter also includes a filter pad selected for durability which is disposed immediately adjacent to the desiccant, to cushion and protect the fragile fiberglass from aggressive action by the dessiccant. Annular perimeter rings are disposed between the dessicant and the composite filters to prevent desiccant migration past the outer perimeters of the composite filters.

A refrigerant drier comprising: a generally cylindrical, tubular body member having a wall defined by inner and outer surfaces which are symmetrical about a longitudinal axis, and first and second axial ends adapted for connection in a refrigeration system, first and second perforated support plates disposed in spaced parallel relation in said body member, transverse to the longitudinal axis of said body member, said first support plate being axially slidable within said body member, in close proximity to said inner surface, said second support plate being fixed, desiccant material in said body member, between said first and second support plates, spring means urging said slidable first support plate towards said fixed second support plate, to maintain said desiccant material in compression, and means allowing said slidable first support plate to move axially towards said second support plate in response to urging by said spring means, while preventing movement of said first support plate in the opposite axial direction, to maintain the desiccant material in compression and reduce the generation of refrigerant contaminating dust caused by the attrition of the desiccant material when vibrated.
