Four Legged Windmills

One of the TALLEST windmills on the market!

We now offer a four-legged windmill tower for customers who prefer to have an extra leg! We’ve sold thousands of towers with 3 legs, but some customers just want an extra one. Our 20′ towers measures 20′ in height or over 23′ with the head. You can also choose our 24′ tower, which makes the windmill 27′ tall.  Our four-legged windmills come in both galvanized and a broad range of powder coat colors.  Structurally, both the three and four leg towers are sound, and we have not had issues with either one from a high wind situation given our self-governing heads, but some people prefer the look of a four-legged aeration windmill, so to meet customer needs, we added this to our product line up.

  • Bronze windmill head and tail fin with a few feet of the tower showing. It is against a blue sky with light clouds. The view is at an upward angle looking up.

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 73″ head is designed to turn 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 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 see tree leaves rustling in the breeze even when you cannot feel it at ground level. And, with our self-governing head, 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!
