This is our most popular windmill, only with 4 Legs instead of Three. The Outdoor Water Solutions 100% electricity-free windmill aeration system can aerate ponds up to 2-3 acres and operates with winds as little as 3-5 miles per hour. This windmill system is designed to aerate ponds from the bottom up, reducing algae, bacteria and odor. Aeration also adds oxygen and prevents pond stratification and keeps ponds from freezing over in the winter. Windmills feature BalCam Technology designed to minimize bearing fatigue and improve operation. The extra large 73 in. windmill head helps with turning at low wind speeds. The head is also self-governing and designed to turn itself out of the wind at high wind speeds and uses a secure locking mechanism to attach to the compressor. The compressor can produce up to 4.5 CFM of air at a rated 30 psi which means it can really aerate your pond and can also aerate deeper water if needed. System includes the windmill, 100 ft. of 1/2 in. poly-tubing and one air-stone diffuser with backflow valve.
