Southern California Specialty Gas Equipment Spotlight: Gas Purifiers


Here at WestAir Specialty Gases and Equipment, PurityPlus® specialty gases for commercial, industrial, medical, scientific, and agricultural use are what we’re primarily known for selling. But customers recognize they also can rely on us for the equipment needed to transport, cache, monitor, and employ those gases safely. One such kind of equipment they appreciate is our line of gas purifiers.

The Southern California semiconductor industry particularly comes to us for point-of-use gas purifiers that extract impurities down to part-per-trillion (pptV) levels. This degree of purity is imperative for fabricating not only semiconductors but also all manner of display, LED, and solar products.

Specifically, we supply …

  • high-pressure gas purifiers, these built for use in all types of laboratory and industrial projects where oil or water need to be kept away from a gas to increase its usefulness and circumvent equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are built to handle higher capacities at a lower working pressure.
Each of the above have to be used in combination with specially engineered replaceable cartridges that hold one of a number of adsorbents. Subject to the cartridge/adsorbent provided, these purifiers can exclude more than oil and water from industrial process gases; they also have the ability to exclude water from inert gases and saturated hydrocarbons, exclude many particulates, and exclude water from unsaturated hyrocarbons, such as acetylene.
  • a series of gas purifiers specifically designed to exclude up to 1% of oxygen from a hydrogen stream down to a level below 1 ppm. They do this by catalytic action. If the catalytic materials aren’t corrupted (particularly by sulfur and halogens), they’ll perform pretty much permanently and not require regeneration.
