Abstract

suspended air purifier fixture including, a radially-symmetrical enclosure forming an internal cavity and including a peripheral surface having a plurality of circumferential openings and a lower surface with a central opening perpendicular and adjacent to the peripheral surface. A centrifugal fan is located within the enclosure and is coaxial with the central opening. An intake assembly is coaxial with the central opening and includes a vane for directing an intake flow of air through the assembly and into the enclosure through the central opening. An air filter is circumferentially disposed relative to the fan and occupies the space between the vane and the peripheral surface. An output grille covers the circumferential openings to have an exhaust air flow perpendicular to the intake thorugh the central opening. Suspension means are located at the surface of the enclosure opposite to the lower surface for supporting the fixture from an overhead position.
