This is one of Outdoor Water Solutions' most popular product lines—high-quality galvanized windmills reminiscent of traditional farm windmills. Proudly made in the U.S.A., these are not imported products and are built to last 15, 20, or even 30 years.
Each windmill features the exclusive BalCam II™ Technology, which distributes the workload across three internally mounted, sealed bearings—technology that no other company offers. Outdoor Water Solutions is also the only brand to provide a five-year warranty on its compressors, while most competitors offer only one- or two-year coverage.
Having sold thousands of windmill aerators, Outdoor Water Solutions stands firmly behind their quality. Compressor issues are rare, and the company confidently believes its products are the best in the industry.
Everything you need is included with your 20' Wind Powered Pond Aerator.
Reliable Performance
Engineered with precision and built to last. The secret is our new “BalCam II” Technology that allows us to pump more air with a single diaphragm. The benefit to you is that you’ll have fewer moving parts, fewer bearings, and fewer diaphragms to service and maintain.
Use nature’s power to keep your pond clear and vibrant, season after season.
Custom Windmill
The windmill aeration systems can be customized for your particular farm, ranch, golf course, subdivision, or park setting.
Easy Installation and Maintenance
Even though the windmills reach impressive heights from base to fan blade tip, the windmill aeration system is simple to set up and includes everything you need to start aerating right out of the box. Most people can do it in just one-two days.
This means you can begin aerating your pond or lake in no time!
