Radial aerator AR series

AR radial aerators are equipment composed of a submersible motor, with impeller for aeration and agitation in sewage systems. They are a very flexible, versatile aeration system when the mixing of a fluid with air supply is required. This aeration system is based on the Venturi principle, introducing a secondary fluid (atmospheric air) into a primary fluid (water), which produces an effective mixture, creating an optimum aeration and suspension of the solids, by means of a star-shaped impeller, and consequently a good transfer of oxygen and agitation in high and moderate concentrations of suspended solids. It can be installed without emptying the existing tank, and without making special installations. For large tanks it is supplied with removable diffuser channels, which increase the contact time and the influence zone, improving the transfer efficiency. Characteristics The AR radial submersible aerator is installed submerged, with a pipe that sucks the air, which then transmits it to the water. Star-shaped impeller The Impeller rotates inside a plate-shaped chamber, creating a depression, which through the suction tube, generates a suction of atmospheric air. At the same time, a total mixture is produced between the water that reaches the impeller and the air, subsequently producing a radial discharge through the channels of the plate. In this way, the air is broken down into fine bubbles, increasing the transfer of oxygen to the water, ensuring excellent oxygenation and mixing of the entire volume of the tank/cuba. Very compact, robust, and reliable unit, the motor shaft is directly coupled to the impeller.
