Abstract
Abstract This is a device for aerating water comprising (1) a fan within a pumping chamber for drawing air through an intake port and forcing air out an exhaust port therein, (2) a fan enabling means located outside the pumping chamber for moving the fan so that air is drawn through the intake port and out the exhaust port, (3) a means for insulating the pumping chamber from the heat created by the fan enabling means, and (4) a means for dispersing the air flowing out of the exhaust port and into water.
