How It Works

The Kasco Surface Aerator propels water into the air using a powerful propeller. As the water breaks into droplets, it increases exposure to oxygen while releasing gases like carbon dioxide. This process allows the aerator to add up to 3 lbs of oxygen per horsepower per hour, providing rapid and effective water quality improvement.
