Gene,
Are people going to be in your diver lockout? Are they going to
breathe the air?
If your are talking ballast air only, then you can use any
compressor. My experience is that its far easier to maintain one good
compressor, and store a lot of air in cylinders, (that does not mean it is the
only way). I know on the 3 commercial subs I was operationally
involved with, we found it to be true.
I am not familiar with a design in which the air is not purified in any
diver lockout situation where human life support is ongoing.
(Again oil is the main problem)
So, maybe I don't understand the design in question.
There are some low pressure (125 PSI max) compressors available that use
teflon or nylon coated pistons, that are capable of producing safe air.
So, maybe I don't understand the design in question.
Also I was not referring to recharging air bottles while underway during
sub operations, merely having the air stored in bottles of any size to support
the intended mission with an adequate reserve, then recharging the air somewhere
else.
