Let Mother Nature aerate your pond!

This windmill tower looks more like traditional farm windmills and is more stable than the three-legged units. This unit also pumps a large volume of air and has high pressure capability due to large head size for deeper ponds. One-piece welded steel hub secures easily to windmill. Windmill aerators can save $30 to $50 per month in electrical costs, paying for themselves in a few short years.
