Fresno Specialty Gas Equipment Spotlight: Gas Purifiers


It’s certainly no secret that our stock in trade at Fresno Oxygen & Welding Supplies/Barnes Welding Supply is selling specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers are well aware they also can depend on us for everything required to move, cache, monitor, and work with those gases safely. One such category of equipment they really appreciate is our line of gas purifiers.

The Fresno semiconductor industry definitely calls on us for point-of-use gas purifiers that extract impurities down to part-per-trillion (pptV) levels. This sort of purity is requisite for manufacturing not only semiconductors but also [[various display, LED, and solar products.

To be specific, we supply …

  • high-pressure gas purifiers, these models created for use in all sorts of laboratory and industrial research where oil or water must be excluded from a gas so as to improve its usefulness and prevent equipment shutdown.
  • gas purifiers that, while comparable to our high-pressure models, are engineered to handle higher capacities at a reduced working pressure.
Each of these purifiers must used along with specially constructed replaceable cartridges that contain one of a number of adsorbents. Relevant to the cartridge/adsorbent ordered, these purifiers can eliminate more than just oil and water from industrial process gases; they also have the ability to eliminate water from inert gases and saturated hydrocarbons, eliminate many particulates, and eliminate water from unsaturated hyrocarbons, such as acetylene.
  • a series of gas purifiers specially designed to remove up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They accomplish this by catalytic action. As long as the catalytic materials aren’t corrupted (especially by sulfur and halogens), they’ll operate indefinitely and not require regeneration.
