12′ Four Legged Becker Windmill with 50′ poly, 100′ Quick Sink tubing and QS2 diffuser

Four Leg High Volume Windmills

If there is no electricity nearby, this may be your best aeration option. Depending on the wind in your area and the shape and depth of your pond, this windmill can aerate up to two surface acre ponds. Also, this system can be used very effectively for preventing winter fish-kills.

This windmill tower looks like traditional farm windmills and is more stable than the three legged units. It pumps a large volume of air and has high pressure capability for deeper ponds. The one piece welded steel hub secures easily to windmill.

• 6′ diameter head with 12 blades operates in wind as low as five miles per hour
• Produces 2.4-5 cfm (depending on air speed) for ponds up to 40′ deep
• Over speed protection tail section will turn head in high winds preventing over spinning
• Stable, four leg design with 48″ long anchor stakes

• Actual overall height is 3 feet taller than description height
• Five year limited warranty
