The Spin drifter Pond Aerator consists of a EPDM rubber membrane (diameter 250mm) mounted on a Polypropylene disk. The aerator is mounted on a steel support with nylon coating and weighs 5 kg in total. The Pond Aerator was designed to be placed on the bottom of the pond. The Aerated Dome was designed to be installed in an existing bottom drain and the Aerated Bottom Drain is a complete bottom drain with separate connection for the air hose. When air is blown into the membrane, the membrane inflates before any air bubbles are apparent. When it is fully inflated, air bubbles will escape through the 4500 slits. When the airflow is interrupted, the membrane deflates and collapses, closing the slits before any water can flow back into the aerator. The required pressure to blow air through the slits in the membrane is 20 mbar at the recommended airflow. The recommended airflow in a koi pond is 20 ltrs/minute/metre depth per aerator for maximum oxygen exchange to the water. The drawing below shows how the aerator causes the water to circulate inside the pond.
