Over time, the DA-20 display style of pond aerators has proven to be the best way to add vital oxygen to your pond or lake for a healthy ecosystem. A DA-20 display style pond aerator also eliminates mosquito breeding, inhibits algae growth, prevents odors, and keeps your water sparkling clean, while adding spectacular aesthetics!

The DA-20 Display Fountain Aerator is designed to maintain an ecological balance in lakes and ponds by creating both vertical and horizontal water circulation, while simultaneously adding oxygen to the water.

Featuring a stainless-steel, oil-free, submersible motor, the DA-20 is 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 the fall or re-install it 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.

ARL tested and approved to be in compliance with the applicable requirements of UL and the National Electric Code as complete packages.
