Hi Jay,
In your coments on the "nitrox ambient" you
mentioned the following.
If you use a constant flow of
oxygen, optimally this should be equivalent to your rate of consumption of
O2 and is usually accomplished with an orifice. The problem is
that the size of the orifice is very small and can be clogged easily.
Rebreathers that in the past have used this method have been plagued with
clogged orifices and the Navy had numerous warnings concerning this issue in
their course ?Principles of Navy Diving?.
Does this apply to the medical O2 regulators used in Psubs, they regulate a
constant pressure through a small orifice.
Also Phil if you're out there- Do you use an anti fogging
product on the acrylic of your newt suit. If so what is it & is it
removed regularly & with what.
I don't want to put any product on thats going to affect the acrylic.
Thanks Alan
