Replacement Windmill Aerator Head | BalCam® II Wind-Powered

 Aeration Head

Restore or upgrade your wind-powered pond aeration system with the Outdoor Water Solutions Replacement Windmill Aerator Head. Designed to fit existing Outdoor Water Solutions windmill towers, this replacement head is the ideal solution for replacing a damaged unit or upgrading an older windmill head from another manufacturer.

Engineered for maximum airflow and long-term reliability, the system features the industry's largest 73-inch blade diameter, allowing it to capture more wind and deliver 3.0–4.5 CFM of airflow, even in lower wind conditions. When paired with a bottom-diffused aeration system, it helps increase dissolved oxygen, improve water circulation, reduce algae growth, minimize odors, and support healthier fish and aquatic life in ponds up to 30 feet deep.

At the core of the system is the proven BalCam® II compressor, engineered with fewer moving parts to reduce bearing wear and extend service life. Premium stainless steel components, a heavy-duty locking mechanism, and a self-governing tail automatically protect the windmill during high winds, providing dependable, low-maintenance operation season after season.

This replacement head installs easily on compatible windmill towers and can be expanded with additional weighted airline and diffusers as your aeration needs grow.
