Clean Filter Cassettes Description The clean filtering cassettes for clean areas are intended for filtering the air supplied into areas with high requirements for hygiene and particle-free environment, such as operating rooms, intensive care units, laboratories, clean manufacturing areas etc. It is possible to install filters that have a filtration class in EPA, HEPA and ULPA range with rubber gaskets or gel gaskets into the filtering cassettes for the highest possible tightness.
/ 28 | Clean Filter Cassettes Design Material Composition All the clean filtering cassette types are manufactured from a carbon steel sheet with a powder coating surface finish, signal white RAL9003 gloss 30% as standard. Other RAL colours available upon request. The structural joints on the clean filtering cassette casings are consistently welded to ensure the cassette airtightness in front of as well as behind the filter.
