I just found out that the pond is about 14 feet deep
please help
purchasing aerator next month
Take the surface area of the pond in acres, multiply that by half the max pond depth. Multiply that number by 325,851. The number you come up with is the number of gallons of water you need to move at a minimum every 24 hr period, I would recommend moving 1.5 to 2.0 times that amount of water.
Since this is a DIY system, I can furnish you with the formulas and information for you to figure out how much CFM you need.
Here is a chart showing what the Vertex diffuser disks move GPH wise, and they need a minimum of 1.0 CFM per disk to work. At 14' max depth, your system will need to generate the volume of air needed at 9-10 psi. That gives you a few psi for fudge factor.
Rotary Vane, rocking piston or diaphragm compressor, they all are rebuildable; but you need to contact the place where you buy the compressor to see if they have rebuild kits. Vertex has rebuild kits for all their compressors.
