Has anyone looked at the flow curve on the waste water pumps? These pumps are VERY low pressure...the bluediamond has a max charted PSI of only 3PSI and flow has dropped from 5.2CFM @0PSI to only 2.7CFM at 3PSI....3PSI will get air just over 6 feet deep into water. These pumps are very low pressure and not well suited for any water depth over 4-6 feet.
It takes just under .5 PSI to push air one foot deep into water, plus the pressure needed to overcome any friction loss.
Rocking piston or rotary vane compressors have good flow, AND higher pressures for deeper water pond aeration.
As mentioned about condensation, ALL compressed air will get hot and produce water condensation. I don't think I would put it in a low area, even with a check valve. Any valve will eventually fail and at best, your pump is damaged, at worst, it gets the motor wet and causes an electrical fire...
