General Description
The AtmosPure Re-Gen Gas Purifier consists of three distinct systems:
A. Circulation System
B. Purifier System
C. Regeneration Control
Circulation System
The circulation blower continually circulates the inert gas inside the glove
box through the Gas Purifier to remove oxygen and moisture. As the blower
circulates the glove box inert atmosphere through the purifier column, water
molecules are adsorbed by the molecular sieve. Molecular sieve is a
synthetic zeolite that adsorbs all molecules less than 10 angstroms in size.
Oxygen molecules are removed from the inert gas by reacting with the
copper catalyst and forming copper oxide.
Purifier System
A six inch diameter stainless steel column contains 5 lbs of molecular sieve
for H
2
O removal and 5 lbs of a reactant copper catalyst material for O
2
removal. The purifier is equipped with components necessary for
regeneration of the molecular sieve and copper scavenging media.
Attached to the column are:

Two isolation valves (manually operated). These valves are kept
open during circulation of the glove box gas through the purifier and
MUST BE CLOSED during the regeneration procedure.

Three solenoid valves for connecting 4% hydrogen/inert gas mixture,
exhaust vent, and vacuum. These are located at the back of unit.

A flow meter for 10-25 CFH regulation of the 4% hydrogen/inert gas
mixture during regeneration.

A 180 watt electric heating coil imbedded in the purifier media. The
heating coil is used in regeneration of the catalysts.

Ceramic fiber, high temperature insulation.

An exterior metal case to protect all the components.
