摘要：An apparatus and method for pumping air in which ambient air is mechanicallyfiltered and introduced into a stream of water circulating in a closed path and driven by awater pump, the air-water mixture being directed to an air separation chamber in whichthe air- water mixture is forceably impinged against one wall of the chamber to causefrothing of the mixture. The frothing mixture rises through a reservoir of water in theclosed circulatory path into an air plenum chamber above the water level, the air risinginto said plenum chamber being water stripped of pollutants not removed by themechanical filter. Air collects under pressure in the air plenum chamber, the pressure airbeing released through a suitable tube or duct and introduced into a tank of water suchas an aquarium. Apparatus for pumping air comprising a motor means driving a waterpump means having impellers to cause flow of an air-water mixture, air separation meansincluding an outer container and an inner container which receives an air-water mixturefrom the impellers, the outer container having a closed top wall provided with an outerduct and spaced above the level of the water to provide an air plenum chamber, thewater in the outer container being discharged through a pipe means leading to a wateraccelerator system for aspirating air into the water and for accelerating the flow of waterinto the impeller chamber of a water pump means.
