Kasco Surface Aerators (½ HP – 5 HP)
Kasco Surface Aerators are professional-grade surface aeration systems engineered for maximum oxygen transfer, aggressive surface agitation, and continuous-duty reliability. Designed for ponds, retention basins, golf courses, HOAs, and municipal applications, these units deliver powerful surface circulation to rapidly increase dissolved oxygen levels. Whether you're preventing fish kills, correcting stagnation, or maintaining long-term water health, Kasco aerators are built to perform 24/7 in demanding environments.
Kasco Surface Aerators are among the most trusted commercial surface aeration systems in North America.
View Horsepower OptionsSplashy McFun supplies the full range of Kasco surface aerator models, including ½ HP through 5 HP configurations for residential, commercial, HOA, and municipal water management applications.
What a Surface Aerator Does
- Pulls water upward using a high-efficiency motor and impeller
- Creates aggressive surface agitation
- Injects oxygen rapidly into the water column
- Improves circulation in shallow and mid-depth ponds
- Helps prevent fish kills and reduce stagnation
How Surface Aeration Works
⬆️
Water Pulled Upward
High-efficiency impeller lifts water from below and forces it upward to the surface.
💨
Aggressive Surface Agitation
The churning action increases oxygen transfer by maximizing air-to-water contact.
🐟
Improved Dissolved Oxygen
Elevated oxygen levels help prevent fish kills, reduce stagnation, and support long-term pond health.
Why Kasco Surface Aerators Lead the Industry
Higher Oxygen Transfer Per HP
Kasco surface aerators deliver industry-leading oxygen transfer rates (OTR), maximizing dissolved oxygen output per horsepower compared to many generic surface aeration systems.
True Continuous-Duty Motors
Designed for 24/7 operation in demanding commercial environments, Kasco units are engineered for long-term reliability, not seasonal hobby use.
Certified & Safety Compliant
ETL Listed to UL & CSA standards, ensuring electrical safety and compliance for residential, HOA, and municipal installations.
Backed by Commercial Warranty
Up to 3-year warranties on larger horsepower models demonstrate manufacturer confidence in durability and performance.
Oxygen Transfer Performance (OTR)
Kasco Surface Aerators are engineered to deliver industry-leading oxygen transfer rates. OTR (Oxygen Transfer Rate) measures the pounds of oxygen transferred per horsepower per hour — a critical metric for commercial water management.
| Horsepower | Approx. OTR (lbs O₂ / HP / hr) | Best Application |
|---|---|---|
| ½ – 1 HP | ~2.0 – 2.4 | Residential ponds & small retention basins |
| 2 – 3 HP | ~2.5 – 3.0 | HOA & golf course ponds |
| 5 HP | ~3.0+ | Large lakes & municipal water management |

*Actual OTR varies based on depth, water temperature, and installation conditions.
Detailed Oxygen Transfer by Horsepower
Below is a more detailed look at typical oxygen transfer performance by horsepower class under standard test conditions (68°F / 20°C water temperature). Actual performance varies by installation and environmental factors.
The 5 HP Kasco Surface Aerator can deliver up to 15+ lbs of oxygen per hour under standard 68°F (20°C) test conditions.
| Horsepower | Voltage Options | Typical OTR (lbs O₂/hr) | Recommended Application |
|---|---|---|---|
| ½ HP | 120V / 208–240V | ~1.0 – 1.2 | Small residential ponds, decorative retention basins |
| ¾ HP | 120V / 208–240V | ~1.5 – 1.8 | ½–1 acre ponds, light HOA use |
| 1 HP | 120V / 208–240V | ~2.0 – 2.4 | 1–2 acre ponds, supplemental oxygen |
| 2 HP | 208–240V (Single / 3-Phase) | ~4.5 – 5.0 | HOA, golf course, larger retention ponds |
| 3 HP | 208–240V (Single / 3-Phase) | ~7.0 – 8.0 | Commercial & municipal applications |
| 5 HP | 208–240V (Single / 3-Phase) | ~12.0 – 15.0+ | Large lakes, high oxygen demand systems |

Real-World Application Example
Golf Course Retention Pond – Midwest HOA Community
A 2.5-acre retention pond serving a golf course and residential HOA experienced recurring algae blooms and low oxygen events during summer heat waves. Installation of two 2HP Kasco Surface Aerators restored dissolved oxygen levels within days, improved circulation, and reduced algae presence significantly over the season.
Results: Improved water clarity, reduced fish stress, stabilized summer oxygen levels.
