What is ID.me?
The strongest windmill aerator on the market — up to 60% more air pumping capacity than other windmills, using zero electricity. Ideal for remote ponds up to 2 acres with no power nearby.
This four-leg Becker Windmill tower looks like a traditional farm windmill and is more stable than three-legged units, while pumping a large volume of air with high pressure capability for deeper ponds. The large, 72" diameter fan wheel with 12 tapered blades is engineered to start turning in winds as low as 5 mph, while developing high power in strong winds — up to 60% more air pumping capacity than other windmills, using zero electricity. Windmill aerators can save $30 to $50 per month in electrical costs, paying for themselves in a few short years.
Pumps 2.9 CFM at 9 mph wind, up to 5 CFM in higher winds — more than other windmill brands.
Built for strength and durability, with a stable four-leg footprint.
The tail section turns the head 12–15° away from the wind to protect the unit in high-wind conditions.
Pays for itself in electrical savings within a few short years, with zero ongoing power cost.
Add extra poly tubing to reach the pond's edge from a remote windmill location.
Designed for easy assembly and low maintenance, proudly made in the USA.

The Becker Windmill Freeze Control Unit helps keep air lines from the windmill to the pond from freezing. It's recommended whenever the windmill sits away from the pond's edge. If the line starts to freeze, the control valve opens and feeds alcohol into the line to melt the ice, then closes so normal operation resumes.
How big a pond can this handle?
With the Deluxe Kit (20 Foot +), it can effectively aerate ponds up to two acres, depending on shape and depth.
How windy does it need to be to work?
The blades are engineered to start turning in winds as low as 5 mph, and develop high power in stronger winds.
How far can the windmill be from my pond?
Up to 1,000 ft away, using extra poly tubing to reach the pond's edge — great for aerating remote ponds with no electricity nearby.
Do I need the Freeze Control Unit?
It's recommended whenever the windmill is located away from the pond's edge, to keep the air line from freezing in winter.
Which tower height should I choose?
Taller towers catch more consistent wind and can support larger diffuser setups — the 20 Foot + Deluxe Kit is built for ponds up to 2 acres. Call us if you're unsure which height fits your site.
What's the warranty?
Every Becker Windmill is backed by a 5-year limited warranty.
