Q. What about Warranty?

A. See our 5,4,3,2,1 year Warranty on our American Eagle Page of our Web Site. In the past we have sold most all other brands and the folks at American Eagle are the best manufacturer we have ever had the privilege to work with as far as Customer Service, Satisfaction & Warranty Claims.

Q. How deep should my Air Stone Diffuser be placed?

A. The American Eagle Bellow Compressor is capable of pumping 14 to 16 feet deep, however, a study has been done and it has been determined that for best results the Stone Diffuser should rest on the floor of the pond at about 1/2 to 2/3 of the pond depth. Example: if your pond is deepest at 12 feet, find an area in the pond about 6 to 8 feet deep for the Stone Diffuser to rest on the pond floor. See the detailed study in the paragraph below.

The study found that during the Hot Sizzling Summer the fish like to go to the bottom where the water is cooler, if the diffuser were at the very bottom it would bring the cooler water to the surface where it would be heated by the Sun & Warm Temperature causing the entire pond to warm too much. In the Freezing Winter it works just the opposite, the fish metabolism slows down and they go to the bottom for warmer temperature water, if the Stone Diffuser were at the very bottom it would bring the warm water from the bottom to the top and chill the water to almost freezing temperatures. Keep in mind the bottom 1/2 or 1/3 will still get aerated but just at a slower rate so as not to disturb the natural temperature welcomed by happy fish.

DO NOT feed your fish when the water temperature is below 50 degrees. Fish will NOT eat in cold water and the food will decay and foul the water.

Q. How many CFM ( Cubic Feet of air per Minute )

A. Cubic Feet of Air introduced into a pond is far more important than Pressure. It has been estimated by an independent study that the American Eagle can produce up to 6 CFM in strong winds 20 to 25 mph, about 4 CFM at 15 to 20 mph and 3 + CFM in Light to Moderate Breezes. The American Eagle is a High Volume Bellow type compressor taking a 1 & 3/4"Stroke unlike High Pressure Diaphragm types that only make a 1/2" stroke thus The American Eagle can produce over 3 times the volume of most competitors.

Q. Will this Windmill Over speed?

A. NO! American Eagle has a built in Self Governing in the Design of the Wheel. Even though the Eagle uses 3 of the Highest Quality Line Shaft High Speed Grease able Bearings rated for 2,000 rpm it is still designed to turn away from winds in excess of 28 mph to prevent any Over Speeding.
