The Koenders Air Compressor
is the key stone of the the Koenders Pond Aeration System. The Air Compressor is used in both the Koenders Windmills (pictured at left) and in the Koenders Electric Aerators. On the windmill the grease sealed ball bearing air compressor crankshaft is turned directly by the windmill blades. In the Electric Aerator a 10" crankshaft pulley is turned by a v-belt attached to a 2" pulley on the 1/4 hp energy efficient 110v | AC electric motor. Specifications: Maximum P.S.I.: 35 P.S.I. Maximum capacity output: 1.5 cu.ft./min. @ 5 P.S.I. | up to 11 ft. depth The whole concept is designed to send air (oxygen) into ponds to aerate water. |
Wind strikes the blades, turning a crankshaft.Offset, grease sealed ball bearings transfer power from the crankshaft to a connecting rod.
The connecting rod, attached to a diaphragm at the bottom end, acts like a piston to draw air into the system on the down stroke, and force it out into the hose on the upstroke.
The 1/2" stroke produces 1.5 cubic feet of air per minute at 5 lbs. psi with a maximum pressure of 35 psi.
The pressurized air passes through the hose and is released in the bottom of the dugout. A series of 3 check valves ensure a one way airflow through the system, and prevent water from returning back The first valve on the diaphragm, allows air to enter the system. A second, on the top of the compressor, allows air to pass out of the system. A third, in the dugout, releases air into the water.
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 with an aerator -- using an air compressor windmill or an electric aerator, through an air line attached to an aeration stone (that can be placed on a layer of gravel inside a bucket) at a deep spot in the pond -- the rising air bubbles from the aeration stone bring bottom water to the surface where it is exposed to the atmosphere. Thus, large volumes of water brought up by the dissolving air bubbles lose bad gasses to the atmosphere, 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.
