Helium in the Isnp.

Crazyduck · 3rd June 2005, 13:40

Since helium is an inert gas how does this affect the velocity of the gas passing through the scrubber?

With the inspiration being an axial scrubber does velocity become an issue with the increase higher inert gas loading and density of the gas at depth?

I am curious how changing the gas composition for deeper diving directly effects the scrubber.

Thanks, Andrew

I have a sneeking suspision that the diferance exists but its irelevent. The velocity of gas passing through the scrubber is going to be affected by depth, RMV and how hard you packed the scrubber even down to how fast you draw breath.
