Pond Aerators

Sizing is fairly simple. The corresponding HP equals the surface acerage it can aerate properly. For example Kasco's 1/2HP Pond Aerator = 1/2 Surface Acre it can aerate. Another Example would be Kasco's 5HP = 5 Surface Acres it can aerate. The AF model is the most efficient surface aerator in the Kasco Marine Line of equipment.

Kasco pond aerators (also called high oxygen transfer units) are designed to withstand the rigors of farm ponds, commercial aquaculture operations, industrial applications, and municipal waste water plants, but they work in the back yard pond as well. 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.

Auburn University has performed independent product tests and has found that Kasco's aerators’ SAE (Standard Aeration Efficiency) is at least 3.0 lbs. of oxygen per horsepower per hour of operation, making them some of the most efficient and effective units available.

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.
