A scrubber is used in saturation complexes and sometimes in treatment =
chambers if using a long saturation treatment.   In the first case the =
chamber atmosphere is of course mix.  In the second it can be if a =
scrubber is fitted. =20

A scrubber does not "extend the O2 supply" .   It keeps the CO2 level of =
the chamber down so it does not have to be flushed with (expensive) =
helium, conserving the dilutent gas supply. =20

Check with Amron in Escondido, http://www.diveweb.com/amron  They are =
the largest commercial diving equipment supplier in the US.  They have a =
very detailed catalog which will describe the unit.

All

Somewhere, I heard or read of an emergency oxygen therapy kit that  =20
incorporated a scrubber to extend the life of the O2 supply.  This may   =

have been incorporated as part of a portable re-compression chamber.  =20
 Does anyone have any further details (contact, experience of use, =
etc.)?
