A proven low-maintenance, low cost, highly effective method of improving water quality.

Koenders Water Solutions offers a dual diaphragm compressor that pumps double the air volume, ideal for ponds that are odd shaped or larger than 2 acres. Providing more oxygen to the pond helps turn unhealthy and stagnant water into a clean and odor free paradise.

The Koenders dual diaphragm windmill aeration systems use the same galvanized windmill heads that are a perfect addition to any pond or lagoon. They are made with the same 18-gauge galvanized steel and self-governing windmill head which functions with as little as 3-5 mph winds.

The only difference is this Koenders model has two diaphragms instead of one allowing it to pump twice as much air as the single diaphragm windmill units that Koenders has been building for close to 20 years.

The Koenders Dual Diaphragm Windmill Aeration System includes: 16′, 20′ or 24′ Windmill, Double Diaphragm Compressor, 200′ of Airline, 2 Airstone diffusers, 2 Foot Valves and a 2-Way Selector Valve. Up to a 3-year warranty.

We are dedicated to the design, testing and perfecting of our products.
