Abstract: A dedicated-purified air supply system (D-PASS) (104) includes a retrofit fitting (106) configured to support the unit at a window (110) and a structural enclosure (300) coupled to the retrofit fitting (106). The structural enclosure (300) includes a perforated back vent plate (208) defining an air inlet (108), heating elements (310) positioned downstream of the perforated back vent plate (208), a multi-stage filter assembly (320) positioned downstream of the heating elements (310), and an axial fan assembly (600) positioned downstream of the multi-stage filter assembly (320). The multi-stage filter assembly (320) includes a coarse-particle pre-filter stage, a fine-particle filter stage, and a volatile-organic-compound adsorption stage. The axial fan assembly (600) draws air through the air inlet (108) and discharges filtered air through an outlet collar (314) to a flexible round duct (400) for delivery toward a work area (130).
