Windmill Parts

Replacement Parts

Outdoor Water Solutions’ manufacture and carry a complete line of replacement windmill parts for our windmills and many of the other companies on the market. No matter the replacement part, we can help. If you need a replacement windmill head, diaphragm, check valves, blades, blade braces, tail fins, stake clamps, bearings, and even compressors, etc., you’ve come to the right place. Replacement parts for aeration windmills, backyard windmills, garden windmills, decorative windmills, ornamental windmills, small windmills, and more. These replacement parts are manufactured to the same exacting standards as all our windmill aeration systems.

Why is windmill aeration important?

Windmill aeration is ideal for locations where running electricity is impractical or solar is not realistic.  Our windmill aeration systems are suitable for any open area. The 73″ head is designed to spin in even low wind situations. Plus, the blades and front dome have been recently redesigned for better airflow. This keeps your pond or lake aerated even on those calm 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 see tree leaves rustling in the breeze even when you cannot feel it at ground level. And 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. By installing a windmill aeration system, you can put mother nature to work for you and allow her to aerate your pond!

Our largest windmill for aeration stands an impressive 24′, and the tower stands over 27 feet tall when fully erected. If you’re not sure about your location and wind speed, going taller is typically better.  The amount of wind you can capture at 27′ is substantially more than at 15′, especially if you have smaller trees or buildings in proximity.  Any of our three- or four-legged metal windmills are available with our 24′ towers.  You can have your windmill galvanized or powder coated and add a personalized tailfin if you prefer.  This 24′ windmill tower can also be a fully functioning aeration windmill or an Ornamental version if you just want a decorative windmill on your farm or property.
