Three-Leg High Volume Windmill Aerator

Our high-quality Windmill Pond Aerator is constructed of high quality galvanized steel that resists rust.

The blade diameter on all units is a full 73," which is the largest windmill head on the market for pond aeration. This allows these units to pump up to 4.5 CFM of air and still turn at low wind speeds due to the 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.

how do you review when you have not seen it

The item has not been delivered. It was due to arrive last week, but never made it here.

Well Built

I am very pleased with the quality and the air output. It takes a little effort to install but it is a good option since there is no electrical power by my pond.
