ABSTRACT:
The device directs a stream of air onto the top surface of a supply of water contained in a tank. The air is directed onto the water by a diffuser so as to create a turbulence on the surface of the water. The diffuser comprises a plenum which hovers over the water surface as a result of the air flow therethrough. The plenum is formed with a buoyant skirt which allows the plenum to float in the water when there is no air flowing through the plenum. The air leaving the water tank is thus moisturized. The device can be used to remove fibrous contaminants such as asbestos from the air, or can be used as an air humidifier, or the like.
