Kasco pond aerators (also called high oxygen transfer units) are designed to withstand the rigors of commercial aquaculture operations, industrial applications, and municipal waste water plants. With more vertical-pump-type aerators in use in North America than any other manufacturer, Kasco is the clear market leader in products proven to deliver outstanding performance and reliability. Kasco pond aerators dramatically agitate high volumes of water at the surface to maximize exposure of water to the air for valuable gas exchange, greatly improving your pond or lake aeration.Typical applications include commercial aquaculture, agricultural ponds, industrial plants, municipal waste water and backyard ponds. These units are typically selected for surface aeration when a decorative fountain pattern is neither necessary nor desired. All Kasco pond aerators are self-contained, lightweight units that float at the surface with a single power cord returning to shore and two or three mooring lines anchoring the unit. The units are easily installed and maintained by a single person and have proven to be an excellent choice for both continuous duty pond or lake aeration and supplemental aeration for unique applications.
