ABSTRACT:
Floor to ceiling room temperature gradients are minimized by a portable floor mounted upstanding tubular unit having air intake ports adjacent the bottom, an open top with air directing louvers, and an electric motor driven fan having blades spanning the interior of the tube above the ports and substantially below the open top. The unit can be positioned on the floor of a room in an out of the way location and will circulate air throughout the room without causing a draft to minimize temperature variations between the floor and the ceiling of the room. The unit receives air adjacent the floor and projects it in a substantially confined upstanding column to the ceiling where it is dissipated throughout the room area to flow back to the intake ports of the unit.
