Circuit Research has now perfected a 'plastic style' hydrophobic
membrane system.
The membrane can be retro-fitted to the existing canister and is
positioned by replacing the outer mesh ring. The positioning stops
the migration of absorbent dust and moisture on long dives, into
the inhale counterlung. Should a temporary system flood occur in
the exhale circuit, it cannot pass through the absorbent and can
be flushed out of the exhale counterlung exhaust valve.
Should a temporary flood occur in the inhale circuit, then water
is prevented from accessing the absorbent.
The membrane can simply be flushed with fresh water and dried.
