Molecular filters for reliable protection in sensitive areas

The intention of Gas Phase Filtration (also called molecular or chemical filtration) is removing gaseous contaminants from the air that could harmfully affect the occupants, contents or environment of a given space.

Industrial processes and polluted outdoor air can be the source of gaseous air contaminants as seen in the graphic. The type of air contaminants can vary from industry to industry, but the problems are almost the same. Contaminant gases can cause corrosion of sensitive electronics as well as unpleasant odors.

The consequences:

  • health impairments
  • expensive repairs
  • unplanned downtimes

Our Gas Phase Filtration solutions protect sensitive areas of processes and reliably remove contaminant gases, odors and VOCs from the air.

Comprehensive protection for your processes

Every industry faces different challenges in regard to occupational and process safety with their specific raw materials or manufacturing processes. Some of these disruptive factors can be traced to the development or presence of undesirable gases. Therefore, the individual requirements need to be identified in order to design the most effective Gas Phase Filtration solution. Our current focus is on corrosion control with electronics as well as odor and VOC control with chemical filtration.
