Give your pond the oxygen it needs without the cost and hassle of electricity. The Outdoor Water Solutions Functional Windmill Head is engineered for one purpose: reliable aeration that works where electric systems can’t. With the largest 73″ blade diameter on the market, this windmill head moves more air at lower wind speeds-delivering 3.0–4.5 CFM. That means healthier fish, clearer water, and less algae-even in ponds 30 feet deep. Every component is built for performance and longevity. The BalCam II technology minimizes bearing fatigue, while stainless steel parts and an advanced locking mechanism ensure dependable operation year after year. The complete kit includes: tower, windmill head, 1 airstone diffuser with check valve, 100′ of airline, and all necessary fittings. Easy installation with included hinges. Upgrade anytime with additional diffusers and airline for larger coverage.

A self-governing tail design automatically protects against overspeed, giving you confidence in every breeze. This head-only system is the perfect solution for upgrading an existing windmill tower. It ships complete with compressor, blades, tail, airline, and diffuser-everything you need for a fast, seamless install. Backed by a 5-year warranty, it’s built to last, built to perform, and built to make your pond thrive.
