I happened across this site today. Thought this
might be of use to dry ambient sub builders who by using this might not
have to have a mouthpiece in their mouth
to expell their co2 out of the cockpit like in this
link's illustration.....http://www.prismnet.com/~moki/20031101.134520/air_supply.jpg
or get headaches from CO2 contaminating their cockpit bubble.
Also you wouldn't have to give your bubble a shot
of fresh air (which still mixes with your CO2 unless you expell it with a
mouthpiece & tube outside of the cockpit)and if you had your bubble set up
so that when you breathed in WITHOUT a mouthpiece
it opened a diaphram and let air into the bubble, these scrubbers might enable you to close off your
air valve at intermintant times and conserve on your air.
This means you could use a smaller air tank and
conserve on space and weight in your ambient sub as well as breath without a mouthpiece.
Make sure you always have a small "bailout bottle" with you in the cockpit for emergency uses just
in case.
Of course an ambient sub operator has to adhere to
no decompression diving codes just like a
scuba diver because of nitrogen buildup in their
body due to the pressurized cockpit air bubble they are in, so the
scrubbers might suffice them for their dive
time.
