How does your Windmill Aeration system work?
The Koenders Free Air Windmill has a top mounted compressor driven by wind which pushes air through the airline to the bottom of your pond.
I have a dirty pond but it is in a location where there is virtually no wind. Do you have a product that would aerate this pond?
You can use our Windmill with up to 1000′ of airline, or you can use our Electric Aerator with up to 1000′ of airline, provided you have access to electricity in the area you wish to place the Electric Aerator.
How much maintenance is required for your Aeration systems?
You should inspect your equipment once a year, as part of your routine maintenance.
Depending upon the environment in your area, you may need to replace the diaphragm and/or insert valves every 2 – 5 years, although we do have customers who are using original equipment still, after 15 years of use.
How long will my Windmill or Electric Aerator last?
You can expect your Koenders Windmill or Electric Aerator to give you 10 – 15 years of faithful service. We have customers who are still using their original equipment purchased in 1988.
