ABSTRACT:
Two oscillating air fan assemblies are attached to arms which are slidable around and along a three piece screwed-together pole. Each fan is adjustable in multiple ways, and can be locked in place for efficiently cooling humans and things. The apparatus is readily disassemblable, for efficient shipping. Each molded plastic arm has holes and a hollow interior with a post through which runs the wire connecting the fan assemblies, so it is adequately secured.
