Scott Aerator DA-20 Display Aerator for Large, Commercial Ponds

The DA-20 is a heavy-duty floating display aerator designed for large commercial ponds that need substantial water movement and oxygen transfer. Its funnel-shaped spray creates a prominent water feature while circulating hundreds of gallons of water per minute throughout the pond.

Available in 2 HP and 3 HP configurations, the DA-20 produces flow rates of 700 or 800 gallons per minute. The circulation helps distribute oxygen through the water, move surface debris and support healthier pond conditions while providing a visible focal point for commercial properties, golf courses, neighborhoods and other large landscapes.

The oil-free stainless steel submersible motor is designed for continuous operation and is approved for fresh and salt water use. The unit can remain in the pond during winter. Power should be turned off during freezing conditions and restored after the water thaws.
