1. An air moving system comprising:

  • a ceiling structure comprising a first ceiling level forming a base portion of the ceiling, the first ceiling level having a plurality of grid cells, each grid cell bordered by a grid cell periphery structure, the ceiling structure further comprising a second ceiling level separated from the first ceiling level by a first height;

    an air moving device positioned at least partially within one of the grid cells in the first ceiling level, the air moving device comprising;

    a housing member forming an interior space within the air moving device, the housing member having a top surface, the housing member being positioned within the ceiling structure such that the top surface is located between the first and second ceiling levels;

    a ceiling support structure forming an outer peripheral edge of the air moving device and attached to the housing member, said ceiling support structure defining an exposed lower surface, the ceiling support structure supported by the grid cell periphery structure;

    the housing member comprising a plurality of air vents for directing a volume of air into the interior space of the air moving device, the air vents having an upstream end and a downstream end,a rotary fan assembly mounted in the interior space and supported by the ceiling support structure, the rotary fan assembly comprising an impeller and a plurality of blades, the rotary fan assembly configured to direct the volume of air within the interior space, the rotary fan assembly having an upstream end and a downstream end; and

    a nozzle communicating with and extending downwardly from the rotary fan assembly, the nozzle comprising a structure for further directing the volume of air out of the air moving device, the nozzle defining a spherical surface which cooperates with a surface of the housing member to enable the nozzle to pivotably rotatably move with respect to a longitudinal axis of the air moving device;

    wherein the downstream end of the air vents is positioned adjacent the downstream end of the rotary fan assembly; and

    wherein the housing member comprises a plurality of ring-shaped structures of varying diameter connected to one another, wherein gaps exist between each of the plurality of ring-shaped structures, the gaps forming the plurality of air vents and wherein the surface of the housing corresponds to a widest portion of an interior of the nozzle as measured perpendicular to a longitudinal axis of the nozzle.
