The Most Asked Questions & Answers On Pond Aerators
How does it work?
Strictly wind-driven. No electric bills to pay.
How many MPH winds does it take for it to startup?
When it is new it takes about 8 – 10 MPH, once it’s been broken in it will take 3-5 MPH winds to start.
What if the winds get too strong?
The way the fins are angled and the size of the tail fin it will turn out of the wind and slow down by itself, you
don’t have to be there to shut it down, there is no break on the windmill, we would rather see it turning, avoiding
unnecessary stress on the windmill.
How fast does it spin before it slows down?
85 – 90 RPM.
How many CFM’s does it put out?
3 cubic feet at 15 MPH of wind. It all depends on the wind speed.
What is the size of the fan?
The windmill fan blade is 60” in diameter.
What kind of pump is it?
It is a heavy rubber airbag. Made by Good Year Tire.
What is the life expectancy of the pump?
We have been using these since 1997 and have yet to experience a problem.
What is the structure made of?
It is all aluminum and stainless steel nuts and bolts.
What if there is no wind and the pond freezes over?
As soon as the wind picks up enough to turn the windmill fan it will open it up or melt the ice.
NEVER WALKOUT TO CHECK THE ICE WHERE THE DIFFUSER IS.
Does it work in all seasons and ice build-up on fans?
It does work in all seasons, the ice build-up has never effected the fan.
What is the diffuser?
A device with thousands of tiny holes in it to distribute the air bubbles (or oxygen) we use a diffuser that is made of
rubber the same they use in sewage ponds it will not clog or gum up, also serves as check valve so the water can’t back
up into the airline to freeze up. It is set at the bottom of the pond or approximately 10ft to 12ft of water depth.
How big of a pond does it aerate?
It will depend on the wind, you have to set this windmill where it can get a good source of wind. The diffuser is designed for a 2-acre pond with continuous airflow. Remember you are depending on the wind speed.
Does the airline freeze during winter?
Is the airline weighted to keep it from floating on top of the water?
We have weighted airline and non-weighted airline, you can choose when purchasing the aerator. The non-weighted
airline comes with the windmill.
Can you hook more than 1 diffuser to 1 windmill?
Yes, you can, but you have to hook up control valves so you can adjust the airflow to both diffusers, the 1 that is going to release the air is the one that is in the more shallow waters.
In the winter does it keep an opening in the ice?
Yes, as long as the wind is blowing enough to keep the windmill fan turning.
How to determine the size of the windmill to the size of the pond?
If you are in wide-open space 20ft will do, but if you are in a low spot you need to get up high enough to catch the wind. You may have to go with a 30ft windmill. Or you can add more airlines maybe up to 300ft, again remember you need to have wind to drive the windmill.
How is the windmill anchored?
The windmill comes with anchors, they are 32” long with an 8” x 10” plate welded to the bottom, they need to be buried 32” in the ground.
Is there any kind of warranty?
Yes, 1-year workmanship.
Does lightening have any effect on the windmill?
The windmill is grounded through the anchors.
