Purifiers/Filters

Filters for Specialty Gases and Liquids

Gas and liquid sample analyzer filters help protect analyzers
from sample impurities by removing solids and liquids from
gases with 99.99% efficiency at 0.01 micron. Sample filters
offer liquid filtration efficiency to 2 micron or lower.

Typical Applications
n Gas and liquid sample analyzers
n Cylinder gas filtration

Features and Benefits
n Remove liquids and solids from gas samples
n Remove solids and gas bubbles from liquid samples
n Coalesce and separate two liquid phases
n Filter solids and liquids from gases with 99.99% efficiency
at 0.01 micron
n Inert to most gases and liquids
n Temperature resistance to 300 F (150 C)
