Purifiers/Filters

High and Low Pressure Purifiers

The SG6140 purifier is designed to remove water and/or oil from gas or liquid streams. It protects
sensitive instruments, prolongs service life and provides more accurate, reproducible test results.
This purifier may be used with non-corrosive gases compatible with brass and Viton at pressures up
®
to 3000 psig. Three different purifying elements are available (see Ordering Information and Optional
Equipment). These elements can be replaced without removing the purifier from the process line.

Low Pressure, High Flow Purifier (Model AG6170) Section E – Gas Handling Equipment
The AG6170 purifier protects sensitive instruments from water and/or oil contamination which
ensures more accurate, reproducible test results and prolongs the instrument’s service life. This
purifier (capable of removing up to 20 times more water than our Model SG6140), may be used
with non-corrosive gases compatible with aluminum and neoprene at inlet pressures up to 350 psig.
Three different purifying elements are available (see Ordering Information and Optional Equipment).
These elements can be replaced without removing the purifier from the process line.
