Kasco® Surface Aerators lead the market with more installations than any other manufacturer. In an independent study by Auburn University, Kasco® Aerators were found to deliver up to 3.0 lbs of oxygen per horsepower per hour of operation, proving them to be some of the most efficient and effective units on the market. Built for dependable, continuous operation, Kasco® Aerators have a proven record in a multitude of applications, ranging from ponds and lakes to salt water and other corrosive environments. Other applications include commercial aquaculture, agricultural ponds, industrial plants, municipal wastewater, backyard ponds and much more.

Introduce more oxygen faster with Kasco® 3 hp Surface Aerators.  The high-performance design of these aerators uses a single open propeller to create and push water droplets into the air allowing efficient transfer of oxygen to the water. Agitation and movement created by the process spread the oxygenated water throughout the body of water.  These units can operate in as little as 24 in. of water.

Kasco’s 3 hp 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® 3 hp Surface Aerators are ideal for ponds/tanks with surface areas of about 3 acres.  All units come with a float and three 50 ft. (15m) mooring lines.

 Available in 240-Volt only.
