Interested in purchasing a pond aeration system?  You might want to read this first!

Pond aeration is the process of adding oxygen to water in order to increase oxygen levels and avoid stagnation.  it helps in reducing fish kill and improves the overall health of your fish and pond water.   Aeration systems are critical if the pond is being used to water cattle or horses or being used for any other form of farming or recreational use.  

If you are in the market for a product to aerate your pond, aeration windmills have consistently been a great tool to aid farmers and pond owners in tackling the issues caused by stagnation and nutrient pollution in their waters. There are numerous choices on the market when it comes to picking a windmill so we thought we would point you in the direction of yet another resource that might help you decide which product or brand is best suited for your needs.

The only study that we have seen comparing different compressor designs is available for download at Koenders Water Solutions. They review 4 different windmill aeration designs and name Koenders compressors specifically in the study due to the fact they own so much of the current market share, estimated at 85-90%.

This technical document has been written in a way that consumers can understand and explains how manufacturers use technical specifications on advertising documents that mislead potential customers on actual product performance. It gets to the bottom of what these specifications really mean to you and your pond!

The study tested a single diaphragm compressor, a balcam compressor, a double diaphragm compressor, and a bellows compressor at different depths of water and wind speeds. The results focused on cubic feet per month of air being produced, instead of cubic feet per minute.  Cubic feet per minute is merely a bench tested result and cubic feet per month is what a windmill aeration system will actually produce in the field; a metric that is as close to reality as possible and which seems to be a much better indicator of performance. In the field, you have wind speeds to calculate performance but also pond depth which yields a corresponding PSI of back pressure rating.
