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 waste water, backyard ponds and much more.</p>\n<p> 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.</p>\n<p> Kasco has designed their surface aeration products through nearly 50 years of experience and knowledge to ensure we are delivering the best. Kasco’s AF Series Surface Aeration units:</p>\n<ul>\n<li> Ensure a lower overall operating cost while delivering an extremely high dissolved oxygen level.</li>\n<li>Are manufactured with a hard-face internal mechanical seal for protection against leaks, and are flood oil lubricated for excellent heat dissipation.</li>\n<li>Feature a corrosion resistant, stainless steel design. This also makes them extremely dependable in salt water applications.</li>\n<li>Increase fish growth and population density while providing efficient water and food circulation with little or no bottom turbulence.</li>\n<li>Backed by a two year warranty (3 year for the 2, 3, and 5HP.)</li>\n</ul>\n<p> All Kasco Surface Aerators are self-contained, lightweight 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.</p>\n<p> <span style=\"font-size: medium;\">Prices vary depending on the length of the cord.

Larger units (1‑2 HP or more) suit deeper or heavily loaded water bodies. Contact a sales consultant for guidance</p>\n</div>\n<div class=\"accordion\"><span></span><span>How shallow of water can it operate in?</span></div>\n<div class=\"panel\">\n<p>Some Kasco models operate in depths as low as <strong>15‑19 inches (≈ 1.25‑1.6 ft)</strong> depending on model.</p>\n</div>\n<div class=\"accordion\"><span></span><span>What benefits will I see besides aesthetics?</span></div>\n<div class=\"panel\">\n<p>You’ll get improved circulation, increased dissolved oxygen, reduction of stratification, fewer odors, and better health for fish and plants.</p>\n</div>\n<div class=\"accordion\"><span></span><span>What is the power/amp draw to watch out for?</span></div>\n<div class=\"panel\">\n<p>Amp draw varies by model/voltage. For example, 1 HP 120 V units draw around 11.3 amps. (Model: 4400AF)</p>\n</div>\n<div class=\"accordion\"><span></span><span>Is installation difficult?</span></div>\n<div class=\"panel\">\n<p>No—the unit floats, is moored with 2‑3 ropes, and has a single power cord returning to shore. Setup can be done by one person.</p>\n</div>\n<div class=\"accordion\"><span></span><span>What maintenance is required?</span></div>\n<div class=\"panel\">\n<p>Periodically clean the motor housing, check the sacrificial anode for corrosion, inspect moorings and power cord. Low maintenance overall.</p>\n</div>\n<div class=\"accordion\"><span></span><span>Does it work in saltwater or harsh conditions?</span></div>\n<div class=\"panel\">\n<p>Yes—many models feature corrosion‑resistant stainless‑steel and are built for freshwater, brackish or saltwater use.</p>\n</div>\n<div class=\"accordion\"><span></span><span>How many cord length options are available?</span></div>\n<div class=\"panel\">\n<p>Power cord lengths are available from 50 ft up to 400 ft depending on application and model.</p>\n</div>\n<div class=\"accordion\"><span></span><span>Will it fit small ponds or is it only for large lakes? </span></div>\n<div class=\"panel\">\n<p>It fits a wide range—models start at ½ HP (for smaller ponds) and scale up. You just need to size for your acreage, depth, and load. Contact a sales consultant for guidance.</p>\n</div>\n<div class=\"accordion\"><span></span><span>What warranty coverage does it have?</span></div>\n<div class=\"panel\">\n<p>Warranty is 2 years for ½, ¾ and 1 HP units; 3 years for 2, 3 and 5 HP

Kasco Surface Aerator | Lake & Pond Aeration
Description
Kasco Surface Aerators
We 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 waste water, backyard ponds and much more.
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.
Kasco has designed their surface aeration products through nearly 50 years of experience and knowledge to ensure we are delivering the best. Kasco’s AF Series Surface Aeration units:
- Ensure a lower overall operating cost while delivering an extremely high dissolved oxygen level.
- Are manufactured with a hard-face internal mechanical seal for protection against leaks, and are flood oil lubricated for excellent heat dissipation.
- Feature a corrosion resistant, stainless steel design. This also makes them extremely dependable in salt water applications.
- Increase fish growth and population density while providing efficient water and food circulation with little or no bottom turbulence.
- Backed by a two year warranty (3 year for the 2, 3, and 5HP.)
All Kasco Surface Aerators are self-contained, lightweight 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.
Prices vary depending on the length of the cord. Call and talk to our Lake & Pond Experts. Tell us little more information about your body of water and we will quickly be able to determine which model or models will work best for your application.

FAQ
FAQs
What size unit do I need for my pond?
As a guideline, use about ½ HP per surface acre for typical pond use. Larger units (1‑2 HP or more) suit deeper or heavily loaded water bodies. Contact a sales consultant for guidance
How shallow of water can it operate in?
Some Kasco models operate in depths as low as 15‑19 inches (≈ 1.25‑1.6 ft) depending on model.
What benefits will I see besides aesthetics?
You’ll get improved circulation, increased dissolved oxygen, reduction of stratification, fewer odors, and better health for fish and plants.
What is the power/amp draw to watch out for?
Amp draw varies by model/voltage. For example, 1 HP 120 V units draw around 11.3 amps. (Model: 4400AF)
Is installation difficult?
No—the unit floats, is moored with 2‑3 ropes, and has a single power cord returning to shore. Setup can be done by one person.
What maintenance is required?
Periodically clean the motor housing, check the sacrificial anode for corrosion, inspect moorings and power cord. Low maintenance overall.
Does it work in saltwater or harsh conditions?
Yes—many models feature corrosion‑resistant stainless‑steel and are built for freshwater, brackish or saltwater use.
How many cord length options are available?
Power cord lengths are available from 50 ft up to 400 ft depending on application and model.
Will it fit small ponds or is it only for large lakes?
It fits a wide range—models start at ½ HP (for smaller ponds) and scale up. You just need to size for your acreage, depth, and load. Contact a sales consultant for guidance.
What warranty coverage does it have?
Warranty is 2 years for ½, ¾ and 1 HP units; 3 years for 2, 3 and 5 HP units.
