I have the occasion to fill an auxillary tank from my main compressor tank.
The auxillary tank has the ability to be filled *as* the main compressor
tank fills, or be filled *after* the main compressor tank has reached
pressure.

Will waiting until the main compressor tank has filled reduce the amount of
condensation in the auxillary tank?

My thinking is that as the air is compressed, water comes out of the air as
the pressure is increased, and that by filling from the main tank after it
has come up to pressure, the air transfered will have already lost the water
it carried in the main tank, and result in less condensation in the
auxillary tank.

Any thoughts on this?

Thanks,

Jon
