Abstract
Abstract A pedestal fan which is lightweight, is readily capable of disassembly for shipping, storing and use which includes a base with optional weight, a two-piece tubing member one piece of which is detachably retained in the base, the pieces retained together by a connector, and with the other tubing piece detachably retained in a yoke which supports a fan outer housing which is tiltable for air direction variance, which housing contains a fan motor and blade and provides air flow. The tubing pieces are of different lengths which permits mounting the housing at different heights above the base for multi-height cooling needs.
