Well water enters the unit from the well pump and is sprayed through the special non-clogging nozzles creating a fine mist, thereby releasing the gases from the water. With the indoor model, gases are then vented outside through an exhaust blower. The Duke Aerator contains a submersible pump to supply water to the building, and the aerator is completely assembled and wired for fast installation. Indoor model also includes 115 V exhaust blower. In areas where freezing is not a problem, the aerator can be installed outdoors.
Gasses released from the water simply escape to the atmosphere through vents in the aerator cover.
This outdoor model is the simplest and least costly type of aerator. Where freezing conditions are common in winter, an indoor model must be used. Indoor aerators have a sealed cover on which is mounted an electric powered exhaust fan. Gasses released by aeration are safely vented outdoors through sealed piping. Indoor aerators are usually installed in a basement, heated garage, or in a closet if there is no basement.
