Three Legged Windmill

Designed to last for 15, 20 or even 30 years

This is one of our most popular product lines. High-quality galvanized windmills, just like the old-time farm windmills. Designed to last for 15, 20, or even 30 years, these windmills are made in the U.S.A. and are not an import line. All of our windmills feature our unique BalCam II™ Technology that spreads the workload across three internally mounted sealed bearings. No other company out there has BalCam™ Technology and no one else has a five-year warranty on their compressors. In fact, most of our competitors only offer 1 or 2 years warranty on their compressors.  We honestly feel ours are the best, so we are confident in standing behind them.  Outdoor Water Solutions has sold thousands of these as windmill aerators, and we rarely have an issue with our compressors.  For more information on the best windmill compressor in the industry, you can click here.  We also sell all of our windmills as a non-functioning Ornamental Windmill at a lower price. Call or e-mail us if you want more information on our Ornamental product line.

Why Use Windmill Aeration? - Outdoor Water Solutions

Why Use Windmill Aeration?

Windmill aeration is ideal for a location where solar aeration is not practical, or running electric is not realistic.  Our windmill aeration systems are ideal for any open site. The massive 73″ head is designed to turn in even low wind situations. Plus, the front dome and blade have been recently redesigned for better airflow. This keeps your pond or lake aerated even on those balmy summer days. Standing an impressive 27′, the windmill can capture winds you don’t even notice. To put that in context, at 27′, you will notice tree leaves rustling in the breeze even when you cannot feel it at ground level. Plus, you never have to worry about the wind blowing too hard. Our self-governing head protects against over-turning caused by high winds. Our compressors have you covered with a full 5-year warranty on cams and bearings. When you install a windmill aeration system, you can put mother nature to work for you and allow her to aerate your pond!
