Abstract
An aerator of this invention comprised of a housing, a motor driven cylindrical tube having an open distal end extending through the housing, and propeller blades attached to the distal end of the cylindrical tube. The surrounding ambient air enters the housing and is compressed by pairs of opposing compression blades located therein, with the compressed air being drawn through inlet slots into a central conduit formed by the cylindrical tube, and injected into the water through the open distal end thereof. The aerator may also have optional feed vanes to direct the compressed air through the inlet slots, and fixed fins to redirect the flow of the water past the propeller blades.
