Koenders Windmills

Koenders windmills are a long term, low maintenance way to aerate your pond in all four seasons. By using a Koenders windmill you use no electricity and yet get most of the benefits of an electric bubbler. They come in 12’, 16’ and 20’ heights and should be put up so they will catch the most wind even if it’s 300’ from the pond

 LD8 well water     pump

 Water pumps can also be run off of the windmill to pump water for cattle troughs, cottage or homestead, or for topping up pond water levels .

 Sw16 shallow water pump

With no oxygen transfer, carbon dioxide builds up in the water causing winter kill. The picture above is a windmill supplying an air diffuser with oxygen. The resulting air lifting of water is keeping the surface open for gas transfer to continue.

The Koenders windmill comes in 5-6 boxes, the largest 20’ windmill weighs 270 lbs complete. This will easily fit in most cars or trucks for transport. We also ship by UPS or transport truck anywhere in Canada or USA. We now have special 3/8” weighted tubing to go from the windmill to the air stone. This means no more bricks or weights to hold the tuning on the bottom.

With the air stone on the bottom you can see the results of air lifting  and water movement.
