The AF Series Surface Aerator by Kasco is far more than just a fountain. This floating pond and lake aerator agitates high volumes of water at the surface, maximizing the exposure of water to air for superior pond aeration. Made in the USA.

Built for a wide variety of applications, this aeration unit is often in commercial use for aquaculture, agriculture, industrial plants and municipal wastewater. It works in freshwater and saltwater. This aerator includes thermal overload protection with an automatic reset and a long power cord.

Providing constant 24/7 operation, this aerator greatly improves the oxygen level in pond and lake water. The increase in oxygenation helps pond plants, fish and other aquatic life. This aerator's high pumping volume helps control floating debris, including duckweed. 


These aerating fountains come with a 50' power cord, if you'd like a longer power cord please contact us for a custom order.

For longer cord lengths, please contact us for a custom order.
