This is our most popular windmill, only with 4 Legs instead of three. The Outdoor Water Solutions 100 percent 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. Windmill features 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. Deluxe Windmill Aeration System includes: 20 ft. Windmill with our new patent pending BalCam technology, 100 ft. non-weighted airline, 2 air-stones, 2 ft. valves, 200 ft. of weighted airline, 1 set of tower hinges, 2-way selector valve, 3 hose connector packs, 2 air-stone housing buckets and 2 duck decoy markers. Made of high quality 18 gauge galvanized steel. Recommended accessories include: Freeze Control Kit or Pressure Relief Valve.
