A high-capacity gas purifying system that can remove a combination of oxygen, moisture and hydrocarbons, (greater than C4) from inert gases and hydrogen.

• Clean flow path (gas contacts only metal, glass and FKM seals)
• High capacity and efficiency in a single cartridge
• Easy replacement with twist on/off assembly knob
• Double seal construction for safety
• Check valves protect gas lines during replacement
• Hardware for wall or bench mount
• Stainless steel fittings

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.

A high-capacity, non-hazardous, gas purifying system designed to reduce contaminants in gases commonly used in laboratory applications to low-ppb levels, available in two models.
