CRS ZPure™ H₂O gas filters

CRS gas purifiers and filters

Pure gas is a critical requirement in gas chromatography, spectroscopy, optics, lithography, and numerous other applications in manufacturing and analytical laboratories. The ZPure™ line of filters remove a wide range of contaminants to trace levels.

Features and benefits

  • High efficiency in-line traps with outstanding capacity.
  • High quality activated adsorbents for long purifier life and efficient contaminant removal.
  • Various size and fitting configurations to fit existing installations.
  • Filter lifetime is dependent on quality of incoming gas, and the flow rate.
  • Individually leak tested.

Recommended applications

It can be used to remove water from inert gases, He, Ar, N2, H2, methane and clean dry air (CDA) to low ppb levels. It is recommended for any application requiring ultra-dry gas.

1) The nominal water capacity is determined for an inlet impurity level of 200 ppm H2O. The maximum water capacity is determined for an inlet impurity level of 10000 ppm H2O.
2) Nominal flow rate is the recommended flow rate for an estimated gas purifier life of 1 year. This assumes the following inlet impurities: 1 ppm H2O. The maximum recommended flow rate is recommended for intermittent use only.
