The 4 Legged Aeration Windmill is our most popular windmill. It features four legs instead of three! Our 20 FT Windmill Aeration System includes Air Stone Diffuser and Foot Valve and 100 ft. of 1/2″ regular airline.

The blade diameter on all units is a full 73″ in diameter which is the largest windmill head on the market for pond aeration. This allows our units to pump up to 4.5 CFM of air and still turn at low wind speeds due to our windmill heads’ higher torque. We can also produce up to 30 psi of air allowing these units to aerate ponds or lakes that are 10′, 20′ or even 30′ deep.
