Understanding Your Kasco AF Series Aerator’s Power Usage

Kasco AF Series Surface Aerators are engineered to provide efficient, continuous water movement and oxygen transfer for ponds and lakes. Your operating cost is determined by three key factors:

  1. Motor wattage
  2. Your local electric rate
  3. How many hours per day the aerator operates

Unlike decorative fountains, the AF Series focuses on subsurface circulation and aeration efficiency, using power to move large volumes of water and improve overall water quality rather than producing tall spray patterns.

Recommended Run Time
For best results, AF Series aerators are commonly run 12–24 hours per day, especially in ponds with fish, nutrient load, or water quality concerns. Many owners operate them continuously during warmer months.

Ways to Optimize Your Costs

  • Run the aerator during off-peak electric hours when available
  • Ensure the intake screen remains clear to maintain proper water flow and efficiency
  • Match the aerator size to pond volume to avoid over- or under-aerating
