Kasco Surface Aerators deliver rapid oxygen transfer and vigorous surface mixing for shallow ponds where water quality matters more than a decorative fountain pattern. Kasco recommends this style of aeration for water less than 8 feet deep. For sites 8 feet deep or deeper, compare a bottom-diffused system such as RobustAire. Compare the listed models Model Horsepower Voltage Minimum depth Optional control 2400AF 1/2 HP 120V 17.5 in C-25 3400AF 3/4 HP 120V 17.5 in C-25 3400HAF 3/4 HP 208-240V 17.5 in C-220 4400AF 1 HP 120V 19 in C-25 4400HAF 1 HP 208-240V 19 in C-220 Kasco rates these aerators at up to 3.0 pounds of oxygen per horsepower per hour. Actual mixing and oxygen-transfer performance depends on basin shape, depth, organic demand, weather, placement, and operating schedule. Standard package or bottom screen? Standard packages include the motor unit, selected power cord, float, and mounting hardware. Choose a bottom-screen package where leaves, weeds, or other debris may reach the intake. The screen helps reduce clogging, but it does not replace inspection and cleaning. C-25 and C-220 control panels are optional and sold separately. The listed 1/2, 3/4, and 1 HP units carry a two-year manufacturer warranty. Before ordering Confirm pond dimensions, depth profile, placement, and oxygen demand. A horsepower choice based only on surface acreage can miss important site conditions. Confirm voltage, GFCI-protected electrical service, cord route, and control-panel requirements with a qualified electrician. Plan three secure mooring points and keep the unit clear of swimming areas, heavy vegetation, and obstructions. Never enter the water while electrical equipment is connected or operating. Never run the aerator dry or lift it by the power cord. Test the GFCI monthly, inspect the unit regularly, clean it at least annually, and check the sacrificial anode every two to three months. This listing includes 50, 100, 150, and 200 ft cord options. Contact LakeTech about the 75 ft 1 HP 120V package or longer high-voltage cords. Review the official Kasco Surface Aerator page, read the current installation manual, or ask LakeTech to review the site.
