Title: Non-directional filter dryer

Abstract: A filter dryer for an air-conditioning system, including an elongated housing enclosing loose molecular sieve material, first and second fluid ports into the housing, a filter basket assembly supported at one end of the housing and a screen and baffle assembly supported at the opposite end of the housing. The first filter basket assembly includes a first cup-shaped filter basket which opens away from the first port toward the molecular sieve material. The first filter basket is retained by an annular, U-shaped flange to the inner surface of the housing by press-fit. The screen and baffle assembly includes a second cup-shaped filter basket which also opens away from the first port. The second filter basket includes a radially-enlarged cylindrical screen portion toward the open end of the basket, a radially-reduced cylindrical screen portion toward the closed end of the screen, and an annular shoulder between the radially-enlarged and radially-reduced portions. The second filter basket is also retained by an annular flange to the inner surface of the housing by press-fit. A perforated baffle plate is located against the molecular sieve material and a spring extends between the annular shoulder on the second filter basket and the baffle plate to urge the baffle plate against the molecular sieve material.
