Scott Aerator DA-20 Display Fountain Aerator 3/4HP

Scott Aerator DA-20 Display Fountain Aerator 3/4HP

The DA-20 aerates water at a rate of 450 gallons per minute in a cascading, trumpet-shaped spray pattern. The spray measures approximately 6.8 feet tall with a width of 23 feet.

This flow rate effectively removes algae, maintains clear water, repels insects, and increases oxygen levels in the pond. The addition of oxygen benefits fish and aids in the decomposition of decaying matter on the pond floor. Additionally, higher oxygen levels result in less buildup of muck over time.

The DA-20 features a stainless steel, oil-free submersible motor, ensuring minimal environmental impact. With no oil required and no need for maintenance or a control box, it is the most eco-friendly water aerator available.

The DA-20 is also simple to install, requiring just two anchoring ropes and weights or tethers.

We engineered the DA-20 to be left in the water year-round. There's no need to remove it in the fall, clean and store it in winter, or re-install in the spring. Simply shut the DA-20 off, let it freeze in and forget about it until the spring thaw. Freezing conditions do no damage to the DA-20, even over the harshest winter.

This unit is produced with 70 feet of submersible, 12-gauge power cable. Greater lengths are also available, and special orders are never a problem. We manufacture a two- or four-light set that easily mounts within minutes; this can be added now or at a later date.

The DA-20 is proudly manufactured in the USA and carries an unconditional 5-year motor warranty.

This product is designed for use in either fresh or salt water.

GFCI required. Please disconnect the power source when swimmers are present.
