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 Options Jump to: Performance Compare HP Sizing Help Specifications FAQs Splashy 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 Swipe to view → *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.
