First off, I just thought it was humorous, it is certainly nothing to
worry about.
Given what we are putting into these tanks there is not going to
be much chance of rust.
The air that comes out of concentrators is dehumidified, the zeolyte
absorbs any water in the air.
(The moisture trap is only needed for the input side, to extend the
life of the beds.)
Even after 20 years, if this thing blows with the 2 PSI I can probably
get up to if I close my O2 valves for 15 minutes it was never ready
for it's normal 125 PSI service pressure.
I am gonna go waaaaayyyyy out on a limb here and wager that the
internal pressure relief on the regulators in my concentrators will let
go long before the tank will ever fail.
