Windmills

High Volume Wind Powered Aeration

Let Mother Nature help aerate your pond! These wind driven aerators replace electric units that can cost between $30 to $50 per month to operate. In only a few short years these windmills will pay for themselves! Ideal for aerating remote ponds that do not have electricity nearby! These new windmills are similar to the units we previously offered but feature many new improvements:

• Pumps 3 CFM of air in low winds -- up to 4.5 CFM in 15+ MPH wind!
• Fast, easy assembly -- many steps were completed for you to reduce assembly time
• Redesigned blades with rounded edges for better air flow
• Larger diaphragm and check valves for increased air flow
• Patent pending technology minimizes bearing fatigue and increases longevity
• Effective in as little as 3-5 MPH wind
• Windmills can be places up to 1000' away from pond edge, this is helpful for ponds that are in low areas or surrounded by trees. Windmill can be located in open area with tubing running to the pond. 72" diameter head has 12 blades and is self governing in high winds. 18 gauge galvanized steel parts will last for years in all weather conditions. Oval holes in all parts makes assembly much easier!

Tubing & Diffuser Packages

Select the type of tubing you prefer -- both weighted (easy to install) and non-weighted are available. Due to large air volume of above windmills, airline has increased to 1/2" and air diffuser is the double air diffuser. This allows maximum air flow with increased oxygen and circulation rates.

Four Leg, High Volume Windmills

We now offer a four legged windmill. This tower looks more like traditional farm windmills and is more stable than the three legged units. This unit also pumps a large volume of air and has high pressure capability due to larger head size for deeper ponds.

• 6' diameter head with 12 blades, tapered blade design allows windmill to turn in low wind and yet produce large air volume in high winds
• One piece welded steel hub secures easily to windmill
• Overspeed protection -- tail section turns head 12° - 15 ° away from wind to protect from over speed conditions
• Up to 5 CFM! Windmill pumps 2.9 CFM @ 9 MPH wind, up to 5 CFM in higher winds!
• Intake air is filtered -- filter is reusable and easy to clean; keeps dirt, pollen and debris from plugging up air pump
• Three year limited warranty
• Price includes 100' non-weighted tubing and air diffuser!

Freeze Control

The freeze control option is recommended whenever the windmill is located away from the pond's edge. Anytime air is compressed, condensation is created and can accumulate in the pipeline. During freezing weather this condensation can freeze and stop the windmill from working. The freeze control option constantly checks line pressure. If the line starts to freeze, the control valve opens and feeds Ethanol alcohol (or Rubbing Alcohol) into the line which melts the ice. Then the valve closes and normal operation resumes.

Use renewable energy instead of electricity to aerate your water feature!
