Kasco pond aerators (also called high oxygen transfer units) are designed to withstand the rigors of commercial aquaculture operations, industrial applications, and municipal waste water plants.

“We have a lot of Kasco units and find them to be efficient, dependable, and portable.” – Peter Fritsch, Rushing Waters Fisheries, Palmyra, WI

With more vertical-pump-type aerators in use in North America than any other manufacturer, Kasco is the clear market leader in products proven to deliver outstanding performance and reliability. Kasco pond aerators dramatically agitate high volumes of water at the surface to maximize exposure of water to the air for valuable gas exchange, greatly improving your pond or lake aeration.

“We have used them (Kasco Aerators) for years and they are very reliable. We never have to worry about low oxygen levels.” —Mike, Keo Fish Farms, Keo, AR.

Typical applications include commercial aquaculture, agricultural ponds, industrial plants, municipal waste water and backyard ponds. These units are typically selected for surface aeration when a decorative fountain pattern is neither necessary nor desired. Auburn University has performed independent product tests and has found that Kasco’s aerators’ SAE (Standard Aeration Efficiency) is at least 3.0 lbs. of oxygen per horsepower per hour of operation, making them some of the most efficient and effective units available.

All Kasco pond aerators are self-contained, lightweight units that float at the surface with a single power cord returning to shore and two or three mooring lines anchoring the unit. The units are easily installed and maintained by a single person and have proven to be an excellent choice for both continuous duty pond or lake aeration and supplemental aeration for unique applications.

“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, Clear Springs Trout Farm, Clear Springs, ID

Features & Benefits

  • Efficient / Low Power Use: Highest efficiency design for low power consumption versus competing units. Reduces operating costs over the entire life of the unit.
  • Rugged Motor: Environmentally friendly design with a hard-face internal mechanical seal for protection against leaks. Long-life top and bottom ball bearings. Flood oil lubricated for excellent heat dissipation.
  • Corrosion Resistant: Superior dependability in salt-water or other corrosive environments. All external metal motor, float, and hardware components are of stainless steel composition and protected by a sacrificial zinc anode.
  • Low Maintenance: Clean the motor housing once or twice per year and replacing the sacrificial zinc anode when visibly corroded.
  • Fully Tested: ETL listed to stringent UL and CSA Safety Standards.
  • Ships Easily: Via UPS
  • Dependable: Backed by a two-year warranty (three-year warranty for the 2, 3, and 5HP).

All models include a float and two (or three) 50′ braided nylon mooring ropes and are available with 50′, 100′, 150′, or 200′ (250′, 300′, 400′, or 500′ for 240V models) SJTOW underwater rated electrical power cords.

—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.

- 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.
