Finally-an aeration solution that works as hard as you do.

The 4 Leg Deluxe Windmill Aerator from Outdoor Water Solutions delivers dependable, off-grid pond aeration powered entirely by the wind. Designed for ponds up to 1.75 acres and depths up to 30 feet, this high-performance system boosts oxygen, cuts algae, and supports healthier fish-all without touching your power bill. 

Built with our patented BalCam II compressor technology, it produces up to 4.5 CFM of airflow with fewer moving parts, reducing maintenance and increasing lifespan. The 20’ or 24’ tower allows for maximum wind capture-even in low-wind areas-and its self-governing head protects against damage during gusts.

Includes everything you need: galvanized windmill tower and head, dual-air stone diffusers with non-weighted airline, and a welded steel head for unmatched durability. No electricity. No recurring costs. No compromises.
