ABSTRACT:
An air diffuser assembly for use in combination with an underfloor air distribution system, where the system includes in part a cavity under a floor, having an upper surface, transmitting air under pressure to selected locations above the floor. The air diffuser assembly comprises first and second annular rings threadably engaging one another and secured respectively to above and below the floor, where the first annular ring includes an annular shoulder for receiving a grill assembly. The grill assembly is seated on the shoulder and is in communication with the space above the upper surface. The grill assembly further includes a centrally disposed, downwardly extending, vertically adjustable rod mounting a circular basket at its free end. The basket includes an array of through holes for delivering pressurized air from the underfloor cavity to the diffuser assembly, and means, such as a rod, connecting the basket to the grill assembly to prevent rotation of the basket. Finally, plural, radially extending, fixed vanes are provided and secured about the vertically adjustable rod to discharge air under pressure from the basket and defined sub-chamber to the space above the upper surface to impart a radial spin to the discharged air.
