Scott Aerator DA-20 Pond Fountain Aerator
Scott Aerator DA-20 Display Aerator - Pond Fountain and Aeration System
The DA-20 Scott Aerator combines powerful sub-surface aeration with a clean V-shaped fountain display, giving pond owners a practical way to improve water quality while also upgrading the look of the property. Instead of choosing between a decorative fountain and a true aeration system, the DA-20 gives you both in one dependable unit. It helps combat algae buildup, oxygen depletion, and stale water conditions while creating a more polished, upscale appearance for residential ponds, private lakes, HOA entrances, golf courses, and commercial properties. With seven horsepower ratings from 1/3 HP to 3 HP and up to eleven total configurations across 115V and 230V, the DA-20 gives you the flexibility to match the system to your pond size, site conditions, and available power.
Every Scott Aerator DA-20 is built for customers who want strong long-term value, not a high-maintenance water feature that becomes a hassle after installation. The motor is designed for continuous 24-hour operation with no scheduled maintenance, helping you keep your pond circulating day and night without constant upkeep. Its stainless steel motor housing and marine-grade components are approved for freshwater, saltwater, and brackish environments, making it a smart choice for a wide range of properties. Each configuration also includes a factory-attached SJTOW power cord, and the DA-20 is designed for flexible, non-permanent placement when properly anchored for the installation site.
One of the biggest advantages of the DA-20 is how easy it is to choose a model that fits your goals, whether you are trying to improve water health, create a stronger visual statement, or do both at the same time. Smaller horsepower options offer an efficient solution for lighter-duty applications, while larger models deliver more flow, wider spray coverage, and a more dramatic display for bigger ponds and more demanding installations. If you want a system that looks impressive from the shoreline and works hard below the surface, the DA-20 is built to deliver that combination. The comparison chart and cable calculator below make it easier to narrow down the right configuration so you can buy with more confidence and get the performance your pond actually needs.

Key Features of the DA-20 by Scott Aerator
- Stainless Steel Motor Housing: Sealed motor assembly with marine-grade stainless steel construction resists corrosion in fresh and saltwater, protecting the motor through the full 5-year warranty period. All DA-20 motors are manufactured in the USA.
- Scalable Motor Range: Seven horsepower ratings from 1/3 HP to 3 HP, with dual-voltage options on the four smaller ratings. The 1/3 HP moves 300 GPM for smaller ponds, while the 3 HP pushes 800 GPM with an 11-foot spray height for larger water features.
- SJTOW Power Cord with Watertight Splice: Each DA-20 ships with a factory-attached SJTOW power cord in 12 GA or 10 GA, with 70 foot or 100 foot lengths depending on configuration. Longer replacement cords are available when the power source is farther from the pond.
- Flexible Anchoring Setup: The DA-20 is designed for non-permanent placement, but proper anchoring is still required for stable installation. Minimum anchor weight ranges from 20 lbs per anchor on the 1/3 HP model to 55 lbs per anchor on the 3 HP model, and mooring line is purchased separately.
