NASclean
Gasket Filter (Disc 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 of 0.3 & 1.0 micron are available and the filters can be used in a wide
variety of applications including filtration of the process gases, equipment protection andprotecting the cleanliness of the downstream gas lines.
