Scott Aerator DA-20 Display Fountain Aerator
With a flow rate of 400 gallons per minute, the DA-20 produces a trumpet-shaped, cascading spray pattern that reaches impressive heights of 6½ feet and widths of 22 feet.
This product is designed to effectively remove algae from the water's surface, preventing insects and maintaining a clear and clean pond. It also adds a significant amount of oxygen to the pond, which is crucial for fish health and speeding up decomposition of organic debris on the pond's bottom. Additionally, increased oxygen levels reduce the buildup of muck over time.
Constructed with a stainless steel, oil-free submersible motor, the DA-20 is the most environmentally friendly water aerator available. Benefit from the convenience of no oil changes, minimal maintenance, and no need for a control box.
The DA-20 is also simple to install, requiring just two anchoring ropes and weights or tethers.
The DA-20 was designed for year-round use in the water, eliminating the need for removal, cleaning, and storage in the winter or re-installation in the spring. When temperatures drop, simply turn off the DA-20, allow it to freeze in place, and forget about it until the spring thaw. The DA-20 is durable enough to withstand freezing conditions, even during the harshest winters.
This unit comes equipped with 70 feet of submersible, 12-gauge power cable. Longer lengths are also offered, and custom orders are always accommodated. We offer a two- or four-light set that can be easily installed in just minutes; this option can be added immediately or at a later time.
