Sanitary Industrial Filters For Advanced Compressed Air and Gas Filtration

The newest name in advanced microfiltration technology for industrial compressed air and gas applications is the availability of Sanitary Industrial Filters. These filters offer the performance of standard, widely available coalescing filters, pre-filters, and activated carbon filters, but are manufactured with stainless steel housings and are typically equipped with sanitary inlet and discharge connections. Sanitary Industrial Filters offer a complete filtration solution to users with enhanced filtration requirements, incorporating housings specially outfitted for sanitary applications. Whether combined with a sterile filter for a staged filtration model to achieve the highest level of compressed air or gas purification, or used in tandem with other Sanitary Industrial Filters, these filters make available enhanced housing integrity that delivers the highest grade of compressed air filtration possible for specialized installations with demanding performance requirements.

Typically, this level of compressed air filtration is required by those industries with the highest purity requirements, such as dairy, food processing, beverage, medical, pharmaceutical, electronics, semiconductor, asceptic packaging, and chemical processing. Other applications served by sanitary industrial filters include any industry where sensitive measurement or pneumatic controls are employed.

Just a few of the highlighted benefits provided by a Sanitary Industrial filtration installation include:

  • Employment of high-quality, non-corrosive stainless steel housings for industrial applications that ensures the oxidation commonly found in aluminum housing filters will no longer be a problem.
  • Cleanability is enhanced with stainless steel housings, thereby extending the service life for all installed filtersno matter the filtration model employed.
  • Simplification of filter maintenance during element replacement.
  • Sanitary industrial filters offer filtration efficiencies of up to 99.99998% at 0.01 microns in coalescing filters, depending on the grade of the installed element.

End-user site requirements vary greatly from installation to installation. Some users have need for filters with sanitary connections, while others require NPT or even stub-end connections for welded installations. Still others have need for a combination of these connections. When considering the options available for Sanitary Industrial Filters, it’s critical to employ the unit that offers latitude with respect to customized product integration and installation. Further to physical installation flexibility, process engineers should be afforded the opportunity to customize a staged filtration model in an al la carte fashion to effectively and precisely address their specific needs. In other words, end-user system designs should have the option of employing any number of filter combinations; combinations that include employing any of the full-range of industrial filtration elements available. Specifically, the end-user should be able to select and combine any of all grades of coalescers, activated charcoal, dust filter, and vacuum filter elements for a staged filtration model that serves the requirements specific to their needs. These specialized installations oftentimes require greater flexibility than off-the-shelf aluminum housing filters can provide.

Being a recent innovation, the competitive landscape is limited, but the availability of Sanitary Industrial Filters and their complete range of element types and applications they serve are not. Sanitary Industrial Filters are, indeed, available with not just a full range of element grades and types, but also a variety of inlet/discharge sizes and types, as well as various operating pressure specifications, including high pressures units capable of up to 6,000 psi.
