High performance surface aerators dramatically push high volumes of water into the air. This process increases the overall health of your water and keeps it thoroughly mixed. These self-contained units deliver up to 3.0 lbs of O2 per horsepower per hour of operation, making Kasco surface aerators the most dependable and efficient units on the market. Kasco’s 3 and 5HP AF Series surface aerators now come with a lightweight, 2-blade weedless prop, designed to maximize the unit’s water moving performance and cut through even the toughest aquatic vegetation, all without increasing amp draw. All Kasco Surface Aerators are self-contained units that float at the surface. With just two or three mooring lines anchoring the unit and a single power cord running to shore, these units are easily installed and maintained by a single person.
