Wind-powered Aeration provides your lake, pond, or dugout with bottom-up aeration , which enhances oxygen levels throughout the whole pond, not only the surface, clearing the water naturally, allowing fish, pets and wildlife to live in a healthier environment. By using bottom up aeration, you will prepare and look after your pond for each and every season without stagnant and murky water.

Maximizing Efficiency

Windmill Height

When selecting your windmill height consider the wind conditions in your area, and the surroundings. Ideally locate your windmill in an area free from obstructions. However If there are tall trees you might want to consider a lower tower or contrary for lower trees consider a tall tower. Moreover if the windmill will be located in a valley the tower needs to be tall. Typically the taller the windmill the more wind it can access, providing more airflow.

Single and Dual Diaphragm Windmill Aerator sizes: 12’, 16’,20’ and 24’.

Windmill Positioning

The efficiency of a windmill aerator is directly influenced by its height, positioning and wind availability. By placing the windmill in a higher location and optimizing its actual height, you will increase its exposure to wind. This results in enhanced wind capture and a more effective aeration process.

Sue's Happy With the Campgrounds Lagoon

We have been using the Koenders Aeration Windmill and their Nature’s Pond Blend on our campground lagoon for less than a year and it is making a huge difference in the clarity of the lagoon water at our campground.

Even this early in the season, I am able to see down almost 4 feet compared to no visibility last year at all. I haven’t measured our total suspended solids yet this year but have a filter installation planned for our pumps to address this. I will keep you posted!

The first photo was before and the next was just a few weeks after installing the windmill and putting in the Nature’s Pond Blend late in the fall. You can see it started to work right away.
