Windmill Aerators This is our most popular windmill! Our 20 FT Windmill Aeration System includes Air Stone Diffuser and Foot Valve and 100 Ft of 1/2" regular air line. The 20 FT tower produces 20% more wind at the elevated height compared to the lower height windmills.
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.
