Plumbing Requirements for Circulation, 4%
Hydrogen/Inert Gas Mixture, Vacuum, and
Exhaust Vent
The Gas Purifier has two 3/4" compression fittings for connecting the
inlet/outlet of the circulation system of the Gas Purifier to the glove box inert
gas and three solenoid valves with 3/8" compression fittings for connection to
the regeneration system (Regeneration Control). Refer to Chapter 3: Getting
Started and Chapter 7: Accessories to select the proper Circulation Tubing
Kit for attachment of the AtmosPure Re-Gen Gas Purifier. Labconco offers
neoprene lined tubing kits and stainless steel tubing kits. Labconco also
offers a 3/4" to 3/8" adapter elbow used to connect to 3/8" fittings found on
polyethylene and older style glove boxes. An AtmosPure Regeneration
Tubing Kit should be selected from Chapter 7: Accessories as it provides all
the plumbing to connect the 4% hydrogen/inert gas mixture, vacuum pump,
and exhaust vent. A rotary vane vacuum pump must also be selected from
Chapter 7: Accessories. Rotary vane vacuum pumps establish a very deep
vacuum below 10 microns that allows the copper catalyst and molecular sieve
to be properly regenerated. Chapter 3, the detailed Figures in Chapter 3, and
Figure 3-8 show typical connections for all plumbing.
Space Requirements
The dimensions are shown in Appendix B: Dimensions. Adequate space is
provided to support the Gas Purifier on Labconco Adjustable Base Stands as
listed in Chapter 7: Accessories. The lower shelf of the adjustable base stand
provides a convenient location to place the Gas Purifier on the right side
below the glove box transfer chamber and out of the way of the operator.
Refer to Figure 1-1 in Chapter 1: Introduction.
