Filter helps keep contaminants, condensate out of industrial gases

Witt has introduced a new version of gas filter 77, certified by BAM (German Federal Institute for Materials Research and Testing) for oxygen service. In addition to removing contaminants from industrial gases, the filter keeps out condensate and protects downstream equipment, the company reports.

The company made changes to the product’s material so that it can be used for applications involving oxygen. The filter insert now is made from bronze instead of chromium-nickel-steel. Newly approved elastomers also are used.

The filter with bronze element was tested by BAM and approved for use with oxygen up to 580-PSI maximum operating overpressure. For other gases, the company specifies a maximum pressure of 725 PSI.
