NASclean
Gasket Filter (Tube Type)
R○NASclean® Gasket Filters are housingless filters which can be directly installed as a gasket inmetal gasket seal fitting applications. Therefore, additional installation space is unnecessary,
installation in existing plumbing is possible and filters can be easily exchanged.
Particle retention values as of 0.0025 micron and above are available and the filters can be used
in a wide variety of applications including filtration of the process gases, equipment protection
and protecting the cleanliness of the downstream gas lines.
