All Kasco aerators for ponds 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. Kasco 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.

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.

The Surface Aerator promotes pond health and increase fish health and growth rates

Kasco AF units deliver up to 3.0 lbs of oxygen per horsepower per hour of operation. Increasing circulation and improving dissolved oxygen levels provides many benefits. Some of these benefits include reducing stratification (separation of water into low oxygen and high oxygen layers), reducing odors, lowering nutrient levels which leads to fewer algae blooms and promoting fish health.

  • Pond aeration
