CRS Gas filter and purifier manufacturing capabilities

At CRS we manufacture a popular line of standard gas filters. We also custom design and build gas filters for special applications. Special requests have included the following:

Special combinations of adsorbents to deliver required output purity levels over a range of flow rates
Special fittings or connections for quick-connect, for push-on tube connectors, VCR fittings, or non-standard compression fittings
Special sizes or end treatments
CRS proprietary products include highly sensitive moisture and O₂ indicators as well as very-high capacity O₂ adsorbents
CRS uses cobalt-free indicating moisture adsorbents for gas line dryers, both for high-flow low ppm applications and also to meet medium flow ppb highly demanding requirements. These adsorbents meet European requirements under REACH.

Depending on the detailed requirements, special designs and labeling can be managed for as few as 250-500 filters per year, or less if the deviations from standard products are minor.

Our gas filter products have been used in various industries such as the petroleum industry for standards in hydrocarbon type test methods, the laser and optics industry and medical industries to provide extremely clean, dry gas in critical applications. Many filters are used for additional clean up of output from gas generators, to provide clean gas for high quality welding applications, and most recently we are making arrangements to provide solutions to the semiconductor industry.

Our commitment to quality in our gas filters translates to more efficient and quality analysis, and less down time due to cartridge changes. Some of the design features can be illustrated with the Advanced Filter System (AFS), which can also be configured for special applications:

	Filters have a clean flow path to prevent contamination. Gas contacts only the metal or glass of the filter body and the seals Each gas filter is helium leak checked and must pass rigorous quality standards before shipping, to ensure you receive the highest quality product available Some of our filters such as the AFS I and II, also undergo a pressure test to assess the strength of each filter before use. The strength of the AFS is due to the custom design and high quality materials used in manufacturing. The recommended pressure claim for the AFS is 14 bar but has been quality tested up to 172 bar before failing. Many of our glass indicating filters, as well as the AFS, have a dual seal design at the inner glass tube and at the outer polycarbonate plastic or metal tube. This dual seal system is for added safety to prevent the escape of hazardous gases.
