<p>A readily portable fan device which is usable both as a cooling fan for circulating ambient air and as a device for increasing the flow of air through a register, comprises a housing containing both a fan impeller and an electric motor for driving the impeller, the housing having a skirt surrounding a bottom air inlet and capable of at least partially sealing a space around such register. Extendable leg means are provided which, when extended, hold the housing skirt clear of a floor and allow the device to draw in air under the skirt when used as a cooling fan.</p> |
