Advanced Filter System (AFS) II Replacement CartridgeThe Advanced Filter System (AFS) II removes moisture and hydrocarbons, (greater than C4) to low-ppb levels, from inert gases and hydrogen. It contains high-sensitivity moisture indicator. When the cartridge is depleted the moisture indicator changes from BLUE to BROWN.
The filter has 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 (provided reasonable care is taken during tank changes).
