Sioux Falls Specialty Gas Equipment Spotlight: Gas Purifiers


It’s no secret that our stock in trade at A-OX Welding Supply is providing specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers are well aware they also can depend on us for the equipment required to ship, store, regulate, and work with those gases safely. One such kind of equipment they appreciate is our line of gas purifiers.

The Sioux Falls semiconductor industry particularly looks to us for point-of-use gas purifiers that remove impurities down to part-per-trillion (pptV) levels. This kind of purity is indispensable for manufacturing not only semiconductors but also all manner of display, LED, and solar products.

Specifically, we offer …

  • high-pressure gas purifiers, these models made for use in all kinds of laboratory and industrial applications where oil or water need to be kept out of a gas in order to improve its usefulness and avert equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are made to take care of higher capacities at a reduced working pressure.
Note that these two types of purifiers must used with specially engineered replaceable cartridges that hold one of a host of different adsorbents. Depending on the cartridge/adsorbent needed, 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 remove up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They achieve this by catalytic action. If the catalytic materials aren’t tainted (notably by sulfur and halogens), they’ll operate pretty much permanently and not need regeneration.
