Apparatus for mixing air within a room includes a hollow leg section having, at one axial location, a circumferentially extending outlet section. The leg section is disposed in substantially perpendicular relationship to the circumferentially extending outlet section. The apparatus also includes a fan disposed in spaced relation from the lowest extremity of the leg section and oriented to push a gas into the leg section and out the circumferentially extending outlet section. The fan is dimensioned to draw primary air through the fan, the primary air drawing secondary ambient air. A sleeve shaped first member is disposed in spaced relationship to the hollow leg section and in spaced relationship from the circumferentially extending outlet section.
