Introduce more oxygen faster with 8400AF & 2.3AF 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 spreads the oxygenated water throughout the body of water.  These units can operate in as little as 20 inches (.6M) of water. 8400AF & 2.3AF Surface Aerators are ideal for ponds/tanks with surface areas of about 2 acre.

Protect your AF Series Surface Aerator power cord by adding a flex sleeve cord protector. Made of high strength, abrasion and cut resistant polyethylene, these cord protectors will keep your power cords safe from threats like wildlife, fish hooks and weed whippers.

8400AF & 2.3AF units are available in 240 (60Hz), 480V (60Hz), 220V (50Hz), or 380V (50Hz) configurations. All units come with a float and three 50 ft. (15m) mooring lines. Optional bottom screens and/or control panels are also available.

  • High-efficiency design means low power compensation and low operating costs

  • Ships via FedEx
  • 3 year warranty (2 year for 50Hz models)

“We have used them (Kasco Aerators) for years and they are very reliable. We never have to worry about low oxygen levels.”

—Mike Clark, Keo Fish Farms. Keo Fish Farms is located Keo, Arkansas. Keo specializes in raising Hybrid Striped Bass fry and fingerlings and is the largest producer of these fingerlings in the world. The farm stretches over 1,200 water acres. Keo uses hormonal manipulation for spawning and can produce between 100 million and 120 million fry annually. The fingerlings are eventually moved to earthen ponds. At that point, Kasco Aerators come into play to keep dissolved oxygen levels high.

Kasco Aerators are “THE most effective aerator out there.”

—Steve Abernathy, Owner of Til-Tech Aquafarm. Til-Tech Aquafarm started in 2 large steel and glass greenhouses in 1991 which were originally used for growing hothouse tomatoes. Til-Tech was conceived to supply fresh Tilapia for a few restaurants in New Orleans. Til-Tech quickly became a research facility for LSU Agriculture and Engineering Programs. It pioneered research in green water re-circulation systems using bead filter technology developed by Ron Malone, PhD. Til-Tech soon saw the need for a hatchery and moved all production to their hatchery to supply fingerling Tilapia. Today, Til-Tech is a state of the art hatchery and has the capacity to produce 12 million plus fry annually. Kasco Aerators are used for de-gassing carbon dioxide in the indoor tanks.

“Kasco Aerators have always been dependable and serve us well in our small ponds.”

—Paul Williams, Owner of Owen and Williams Fish Farm.  Owen and Williams Fish Farm produces Largemouth Bass, Hybrid Striped Bass, Sunfish, Channel Catfish, Grass Carp, and forage fish for private pond stocking. Located in Southern Georgia, Owen and Williams Fish Farm uses Kasco Aerators to increase dissolved oxygen levels and help keep fish lively and healthy during the hot Georgia summers.

“We have a lot of Kasco units and find them to be efficient, dependable, and portable.”

– Peter Fritsch, Manager at Rushing Waters.  Rushing Waters Fisheries is the largest producer of Rainbow Trout in the Midwest with 50+ ponds on the farm. Rushing Waters has been raising Rainbow Trout from egg to market size since the 1960′s and process’s the fish on site. They use Kasco 2400AF and 3400AF Aerators in the ponds to increase dissolved oxygen levels which reduces stress on the fish and increases feeding. With many of the 50+ ponds built narrow for better flow through in the raceways, Kasco Aerators are perfect because of their light weight and high water flow.

“A continuing drought in southern Idaho caused spring flows to drop significantly at Clear Springs Foods broodstock facility located in Soda Springs, Idaho. Under normal operating conditions, the Soda Springs facility operates 26 raceways with an average water flow rate of 1cfs and up to 7,000 lbs. of fish per raceway. Declining water flows caused dissolved oxygen levels to drop below 5 mg/L in some second-use raceways, endangering the spawning population and jeopardizing our ability to supply eggs for our trout production farms. To address this problem, Clear Springs installed Kasco 3400AF, 3/4hp aerators at the top of 6 heavily loaded ponds. By maintaining effluent dissolved oxygen concentrations near 6 mg/L, the aerators have reduced stress and improved feed response in these ponds.”

– Doug Foss, Manager of Clear Springs Trout Farm in Clear Springs, ID.
