ABSTRACT:
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.
