This is the Windmill Assembly and Air Compressor,
with the pivot tube mounted through the blue tower top.
In this photo you can see the blue tower top. You can also see that the black pivot tube on the air compressor slides into the blue tower top. But, this photo does not show the air line fitting on the bottom of the blue tower top.
Here is a photo of one type of Rotating Union attached to a fitting on the bottom of the Pivot Tube. The Rotating Union replaces the Koenders Air Line fitting that simply twists inside the Koenders 3/8 inch air line as the Windmill assembly turns on top of the blue tower top.

Pond Aeration: related page |
Where oxygen is really needed in a pond is at the bottom. Pond and lake bed aeration adds oxygen to all of the water, not only surface water, but to the water at the bottom as well. This is very important. Once the lake or pond is full of oxygen near the bottom, new insect larvae, snails, and other fish food can begin to live on the bottom.By pumping compressed air out into the pond or lake bed aerator (from the electric aerator or windmill through an air line attached to an aeration stone), the rising air bubbles from the air stone bring bottom water to the surface where it is exposed to the atmosphere. Thus, large volumes of water brought up by the air bubbles lose bad gasses to the air, and pick up even more oxygen while on the surface (air contains 22% oxygen). Bacteria will breath oxygen if it is available. They like this new oxygen "banquet" in the water so well that they grow very fast, multiplying rapidly to gigantic numbers. Aeration speeds up this process of oxidizing or "burning up" the pollution in the water. Result: fresh, sparkling clear, sweet-smelling water which supports abundant fish life, free from excessive algae and weeds, and is available for live stock.
