Windmill Aeration Compressors

Which Design is the Best?

As demand for cleaner and healthier water increases and as awareness grows in the consumer and commercial markets about the value of water aeration.

Competition is emerging to provide various solutions for this market. One area that seems a little confusing is the noise in this emerging aeration industry surrounding the various air compressors that pump the air from the windmills or electric aerators into the water.

We asked Koenders Windmills – celebrating 20 years in this business and the original manufacturers and innovators of windmill aeration systems why their compressor is the best!( the air compressor is one of the main components in an aeration system – the pump the air from the pump and in to the airline out into the pond).

Koenders has had 20 years experience in building and innovating these products and has over 50,000 customers using them along with a warranty claim ratio that is incredible to say the least – less than .05 % – so we thought it be best that we ask them.

Their Engineers were kind enough to provide us with the following response;

1) It has been proven with engineering and physics that the piston size to blade surface ratio must be in perfect balance such that an aeration system will achieve excellence in performance and reliability in low to medium winds speeds.

2) Koenders has designed their piston size to blade ratio to produce excellent air volumes at high wind speeds as well as providing longer hours of production in lower winds without stalling.

3)Volumes of aeration is determined by the depths that the air diffusers (air diffusers take compressed air and convert it into thousands of tiny oxygen
bubbles that dissolve directly into the water) are placed in the water – this has an impact on back pressure (one pound per square inch of pressure for every 2 Ft of water depth).

4) Larger pistons more air is the theory and in theory this sounds great. But if you design a larger piston that will produce larger amounts of air then you also require more power to drive the larger piston ( for windmills this would mean that you would need higher winds and for electric aerators it would mean that you require more power).

If the larger power requirements or wind speeds are not met then the actual run time of the windmill that aerates the ponds will be dramatically reduced – lowering the amount of aeration running time and actually losing air production time instead of increasing it.

5) Our engineers at Koenders have always taken the approach that windmill aeration is like riding a bike. There are gears on a bike that allow you to change gears when you are going up hills, down hills and riding along flat ground. With the windmills we do not have the option of gears so we designed the windmill to operate in all conditions low, high and medium winds – just like you would a bike if you could choose only one gear to perform all functions in all conditions.

6) Reliability – another design consideration is force – the larger the piston/diaphragm diameter the more force is placed on the connecting rods, bearing sets and other related components. We have designed our pistons to operate in all wind conditions while exerting the least amount of force on the other windmill components. Our track record for this design is proven.
