[PSUBS-MAILIST] Ballast air

[Alan James via Personal_Submersibles]

Hi Adam,that would require a rebreather style set up to do that.I believe they had a rebreather back up on James Camerons sub.A bit expensive & complicated.Alan

For emergencies, wouldn’t you use a full-face mask connected to a CO2
scrubber and air filter and pure oxygen, all on the inhale side...

Compressed scuba air would increase cabin pressure and make things
uncomfortable...

Brian,
I don't mean oxygen, I mean  regular scuba air.  I have and am sure all
other subs have scuba breathing apparatus for emergencies like smoke.  I
take air from my ballast supply for that purpose.  If your ballast air is
Nitrogen then you will need an extra tank for emergency breathing.

 Yes, my oxygen will be a separate
 tank, or tanks.

 Brian,
 You must be planning to have a separate tank for emergency  air for
breathing, in case of fire etc.

  I'm planning on having
  3 - 300cu ft air cylinders for my ballast supply air.
  I noticed that if I get them filled with nitrogen it is
  cheaper than getting breathing or industrial air
  !   That is, until I get my own
  compressor. Brian
