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.

Kasco also offers control panels that do not include lighting circuitry, meaning it will only control when the unit turns on and off. This helps us pass cost savings on to you. The C-220 panels operate 3/4, 1 and 2HP, 240V units, and the C-230 panels operate 3 and 5HP, 240V units. Learn more about these control panels. 

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.

Protect your surface aerator power cord by adding a flex sleeve cord protector.
