Features
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.
Windmill pumps 2.9 CFM @ 9 MPH wind, up to 5 CFM in higher winds!
Over-speed protection – tail section turns head 12° – 15° away from wind to protect in high wind conditions
Includes 48″ long anchor stakes
Includes hinge set
Includes a hinge set for easier installation and maintenance
Maximum pressure of 30 psi
Ideal for aerating remote ponds with no electricity nearby
Windmills can sit up to 1000′ away from pond’s edge – use extra poly tubing to get to pond edge
Five year limited warrantyIn

Becker Windmills (also known as Beckermills) are wind-powered pond and lake aeration systems manufactured in the USA. The primary benefits of the windmill include:

• Raises oxygen levels: Pumps oxygen deep into the water column to support fish, plants, and beneficial bacteria.
• Aids organic decomposition: Accelerates the natural breakdown of bottom muck, silt, and decaying plant debris.
• Destratifies water: Circulates the water column to prevent temperature and oxygen layers from separating.
• Removes toxic gases: Helps purge harmful gases from the lower levels of the pond.
• Reduces odors and stagnant water: Eliminates foul smells and discourages stagnant conditions that breed mosquitoes.
• Controls algae: Improves overall circulation and oxygenation to help curb excessive algae growth.
• Winter deicing: Keeps a small area open during freezing months to help prevent fish kills.


Operational & Design Advantages
• Electricity-free operation: Uses 100% renewable wind energy, eliminating monthly power bills (saving an estimated $30–$50/month compared to electric aerators).
• High air output: Features a large 72-inch diameter fan wheel with 12 tapered blades and a piston diaphragm assembly that is 60% larger than many competing brands, pumping up to 60% more air (over 3.2 CFM).
• Low-wind startup: Engineered to begin spinning and generating airflow in breezes as low as 4 to 5 mph.
• Sturdy four-legged tower: Offers superior structural stability compared to typical three-legged windmill towers.
• Low maintenance: Built with durable, corrosion-resistant materials, a re-cleanable air filter, and permanently grease-sealed bearings.
• Remote placement: Can be set up far from the shoreline (up to 1,000 feet away) where electrical lines cannot easily reach.
Outdoor Water Solutions windmill pond aeration systems harness natural wind power to aerate, circulate, and clean ponds and lakes without electricity.
