Product Overview

For all you folks who own big ponds that need heavy-duty aeration—but who also want a graceful, pleasant-sounding water feature—our hard-working, 3-hp DA-20 Display Aerator was made for you.

The 3-hp DA-20 forcefully moves an impressive 800 gallons of water per minute into an 11-foot-high cascade that can be adjusted as wide as 32 feet or as narrow as 15. Its powerful flow rate not only looks great, it also whooshes algae off the surface, keeps water clean and clear, repels mosquitoes and other bugs, and adds plenty of healthy oxygen to your pond. Your fish will feel fantastic, your pond-bottom much will break up, and decaying matter to come will disintegrate quickly (meaning less muck over time).

The DA-20 features a stainless steel, oil-free, submersible motor, making it the most environmentally friendly water aerator on the market. And, with no oil to add or change and no control box required, it's maintenance-free! The DA-20 is even easy to install, requiring just two anchoring ropes and weights or tethers.

Perhaps best of all, the DA-20 is engineered to be left in the water year-round. You'll never need to remove it in fall or re-install in the spring. Simply shut the DA-20 off, allow it to freeze in and forget about it until the thaw. Freezing water does no damage to the DA-20, even in the harshest winter.

The DA-20 is proudly manufactured in the USA and carries an unconditional, 5-year motor warranty. This unit is produced with 100 feet of submersible, 10-gauge power cable.
