A high-capacity gas purifying system designed to reduce contaminants in gases commonly used in laboratory applications to low-ppb levels, available in two models. The AFS Purifier I removes oxygen, moisture and hydrocarbons, (greater than C4) from inert gases and hydrogen. It contains high-sensitivity oxygen and moisture indicator. When cartridge is depleted the oxygen indicator changes from GREEN to GREY. The Moisture indicator changes from BLUE to BROWN. Both AFS Purifier I and AFS Purifier II have a very high capacity and can be expected to supply four GC’s for at least one year when used with 99.995% pure gas supplies (provided reasonable care is taken during tank changes). The Advanced Filter System Complete Kit includes the AFS Cartridge, Manifold, and the wall and bench mounting brackets.
