Pond Boss Forums AERATION Systems questions More CFM

April 19, 2002

We are working on
a new Air Pump design
that produces more CFM.

More Air Bubbles are good.

We are working on it.
Anyone know of a low AMP
DC gearmotor with a lot of torque?

How about the DC motors used in full size Satellite system actuator arms? They are low draw high-torque and with the near demise of large satellite dish production you may be able to find a cheap suply.

John, More air than what? How many cfm and at what pressure? It would't take much air(cfm) to "out do" the Koenders windmill esp. in low winds. Their cfm rating of 1 -1.5 is only true if the wind speed is 24-30mph look at the research from Alberta Renewable Energy Test Site. Less wind produces fewer bubbles watch the diffuser bubble in low winds for an example of what I mean.
Explain to us how your new unit will be better than a 1/4 hp rotary vane compressor producing 3-4cfm (depth dependant)@ 10psi.

I don't want to belabor the obvious...but...I don't think anybody thinks the windmill aerator is superior to ANY electric aerator. The whole point is that you can have an aerator where you don't have electricity. We use our own products...we're down here in Texas. Our situation is such that we don't have electricity run to any of our tanks (but one). With the cost of putting in electric lines (and the unslightliness) there's just no competition with the windmill. Check us out Wildlife Ranch Supply or email us fence-guy@wildliferanchsupply.com

To All Interested in Aeration. Windmills that create pressurized air that can be delivered to a diffuser on the pond bottom are much better than no aerator to circulate and destratify pond water in ponds that do not have access to electricity. BUT, many windmills do not make much air (1-2CFM), and are not superior low horsepower 1/4 - 1/3 hp rotary vane air compressors which create 4-4.5 cfm. More air obviously creates more bubbles to move more water. But as you point out you need electricity for an electric compressor. When electricity is not an option, now a windmill becomes a valuable and improtant item for keeping the pond's deep water in better and healthier condition.

A windmill aeration system would make a lot of sense in areas far from electricity.

However, IMHO, I would definitely retrofit a "Spillway Syphon System" into the pond to remove the "dead water" at times when the pond reaches spillway levels during higher rainfall months, and will lessen the need for constant aeration.

I have NO commercial interests in any systems.
