AirOxi has come up with its new product Aire-O2 Series II sub-aquatic aerator specially designed for uniform oxygen dissolve at pond bottom. It operates by creating a partial vacuum under the water, drawing air through the shaft and dispersing it into the water in a horizontal direction. As the propeller rotates, it induces a flow of atmospheric air through the air intake ports on the shaft located above the water surface. This air is then drawn through the channel, past the propeller, and exits in a high velocity stream of fine bubbles as it is diffused into the water.
