Still water stratifies and loses oxygen, which lets muck and nutrients build up. Aeration keeps the water moving and oxygenated, supports fish and beneficial bacteria, and helps prevent winter fish kill.

A windmill uses wind to drive an air compressor that pushes air to a diffuser at the bottom of the water, circulating and oxygenating it with no electricity or fuel required, which is ideal for remote and off-grid sites.

It depends on your site: windmills suit windy, off-grid locations; solar suits sunny sites that want daytime aeration without a power line; electric suits sites with power that want continuous, controllable output. Contact us and we’ll match a system to your conditions.

Koenders has designed and built water aeration equipment for decades and ships from our US locations in Huntingburg, Indiana and Albion, New York, supporting operators on farms, acreages and municipal sites.
