Outdoor Water Solutions 3 Leg Steel Windmill Pond Aerator

This system runs entirely on wind, so you can skip the trenching and the utility meter. Set it up near your pond and let nature do the work.

• No power required: wind turns the head, the compressor builds air pressure, and oxygen travels down the airline to a diffuser on the pond floor.
• Starts early: begins producing airflow in as little as 3 to 5 mph winds thanks to the 73" blade.
• Ideal placement: perfect for farm ponds, ranch ponds, remote properties, parks, golf courses, and any spot where running electricity is impractical.

Because the diffuser releases thousands of tiny bubbles, the rising air column circulates your entire water body from bottom to surface. That means increased dissolved oxygen, reduced algae and organic muck, fewer stagnant odors, and a healthier home for your fish.

The heart of this system is the high-output BalCam II compressor, a dual-diaphragm system engineered with stainless steel components and fewer moving parts to reduce wear over time.

• Airflow output: up to 4.5 CFM pushed down to your diffuser.
• Fewer parts to fail: a simple design means less to rust or break down.
• Dual-diaphragm design: when installing the dual-diaphragm system, ensure the internal alignment is flush, as a misaligned compressor causes premature wear and drops your air output.
• Backed for years: a 5-year warranty on the compressor and bearings, plus a 1-year warranty on all other parts.

It is built tough and made to last without giving you any fuss. Set it and forget it.

Your pond investment needs to survive real weather. The rugged 3-leg galvanized steel tower is built from 18-gauge steel for structural strength, and it carries the smallest footprint of the tower options, making it a smart fit for tight installation spaces, narrow shorelines, and uneven terrain.

• Self-governing head: the functional windmill head automatically turns away in high winds to prevent over-spinning, blow-overs, and storm damage.
• Ground-level service: the included heavy-duty tower hinge system and brackets let you pivot the entire windmill down for maintenance, so there is no scary climbing.
• Tower hinges included: everything you need to raise and lower the system safely comes in the box.
• Find your hardware fast: the master bolt package is safely packed inside the Blade and Tail Box, not the tower boxes.

Taller towers catch more wind, which means more consistent airflow. Choose the height that suits your landscape and your wind exposure.

• 24 Feet: $2,895.00
• 20 Feet: $2,595.00
• 16 Feet: $2,495.00
• 12 Feet: $2,395.00

If you can place the tower on a hill, ridge, or open area, even a slight boost in elevation dramatically increases wind exposure. Picking a taller tower does the same thing.

The diffuser sits at the bottom of your pond and breaks the pumped air into thousands of tiny micro-bubbles. Those bubbles lift stagnant water to the surface, breaking down muck and algae while adding vital oxygen for your fish. This base kit includes one air stone diffuser with a check valve and backflow valve.

• Single diffuser systems: perfect for round or square ponds with a simple, open footprint, with a durable self-sinking design.
• Dual diffuser systems: highly recommended for irregular-shaped ponds or ponds with islands, so there are no dead zones where stagnant water can hide.
• Add-on airstone pricing: add two air stones with a valve for approximately 1.5 acre ponds (+ $159.95).

Want more coverage later? You can upgrade to a two-stone setup in high-wind areas without buying a whole new machine.

Standard airline floats, creating an eyesore on the surface and a hazard for fishing lines, swimmers, and boat propellers. This kit includes 100 ft of non-weighted 1/2" poly airline for positioning your tower and running air from the compressor to the pond edge.

• Switch at the bank: transition to weighted airline before the water so the line drops instantly to the pond floor and stays invisible.
• Built to endure: weighted line is constructed from thick, durable PVC that resists kinking and cracking over time.
• Add more when needed: if your tower sits more than 50 feet from the water, or your pond is especially deep or wide, extra airline helps you reach the deepest part comfortably.
• Self-sinking airline lengths: add self-sinking 1/2" airline for your diffusers in 100 ft (+ $199.95), 200 ft (+ $389.95), 300 ft (+ $575.95), 400 ft (+ $745.95), or 500 ft (+ $779.95).

Wind direction changes constantly. The optional Pivot Bearing upgrade is a heavy-duty, low-friction bearing mechanism that lets the windmill head swivel smoothly and instantly to grab even the slightest breeze.

• Lower startup wind: less friction than a standard metal-on-metal pivot means the windmill starts turning, and aerating, in lower wind speeds.
• Heavier duty: built to handle more of what the world throws at it.
• Great for tricky spots: a smart choice for tree-lined or low-wind areas.
• Upgrade pricing: add the Pivot Bearing (+ $99.95).

The base package is a strong foundation, and you can grow it whenever you like. Use the add-on selector to build the exact system your pond needs.

• Diffuser options: add extra air stones, or upgrade to rubber membrane diffusers, which flex as air passes through for naturally self-cleaning, fine-bubble performance in 9 inch and 12 inch sizes. Add one membrane for approximately 1 acre ponds (+ $179.95), or two membranes with a valve for approximately 1.5 acre ponds (+ $399.95).
• Markers: optional Duck or Gator decoys help you locate and lower your air stones. Alligator heads also act as natural pest deterrents. Choose 1 Duck (+ $19.95), 1 Gator Head (+ $59.95), 2 Duck Decoys (+ $39.95), or 2 Gator Decoys (+ $99.95).
• Powder coat finishes: choose galvanized (no color), or add color options including Bronze, Black, Forest Green, Red & White, Blue & White, and Green & Yellow (+ $800.00 each), or the limited-time 250th Anniversary Red, White & Blue finish (+ $1,000.00, ends 7/31). Please allow 7 to 14 business days for powder coat orders.

Every part of this windmill is chosen for durability and low-wind performance. Here is how the core hardware breaks down:

• Tower material: 18-gauge galvanized steel.
• Head and blades: galvanized steel head with a 73" blade, self-governing for high-wind protection.
• Wind requirement: operates in as little as 3 to 5 mph.
• Maximum pond depth: up to 30 ft, with standard guidance of up to 15 ft for single air stone setups.
