Gas Line Filters

®
Series 5000 – Teflon Membrane Gas Line Filter, 0.01 Microns
The medium in this filter efficiently traps particles down to 0.01 microns. These units may
be installed in gas lines supplied by cylinder or bulk sources. Both the materials and
manner of construction render the 5000 Series units compatible with a wide variety of
gases. Any combination of fittings are available. Some typical configurations are shown
in the table below.

Depth Type Gas Filters - 0.2 Microns Series 7100
The 7100 Series depth filters are the work-horses of laboratories and many critical
industrial processes. They are routinely used in critical gas line applications and as
pre-filters to extend the lifetime of more expensive filtration units. They are designed
to provide high filtration efficiency at an economical cost.
The 7100 Series filters employ a microporous fiberglass media held in a
316 stainless steel all welded housing. Any combination of fittings is available.
Some typical configurations are show in the table below.

Features Series 7100
n 100% filtration efficiency at 0.2 micron level n Particles are collected in the filter matrix Depth Gas Filter
n Filter media compatible with a wide range throughout the depth of the filter
of gases n All welded 316 stainless steel construction
n Long service life n Operating Pressure: 250 psig
n Operating Temperature: 0° F to 165° F
