Our Most Popular Display Aerator for Medium, Residential Ponds!
If you have a medium-sized pond (¾-acre) that’s begging for a beautiful, serene-sounding water feature, the 1 hp or 1½ hp DA-20 Display Aerator are made for you.
The 1 hp DA-20 easily moves up to 500 gallons of water per minute. Its trumpet-shaped spray — approximately 7 feet tall by 25 feet wide — not only pleases the eye, it also adds oxygen back into the water. This oxygenation helps control algae growth and pesky insects while promoting a healthy environment for fish and other wildlife.
All Scott Aerator products are built to withstand harsh conditions — no need for complicated or costly winterizing procedures. Simply shut off the power and leave your fountain or aerator in place. When spring arrives and the ice thaws, restore power, and it’s ready to run. Every component is engineered to endure subzero temperatures without damage.
Made in the USA: All Scott Aerator Company fountains, aerators, Aquasweeps, and de-icers are proudly made in Holland, Michigan and carry an unconditional 5-year motor warranty. These products are manufactured using a stainless-steel, oil-free, submersible motor, making them among the most environmentally friendly pond products on the market. There is no oil to change, no maintenance required, and no control box needed. Like all Scott Aerator fountains and aerators, the DA-20 is designed for use in both fresh and salt water.
