The CFC-W is a clean filtering cassette designed to provide high levels of filtration in spaces with exacting hygiene requirements and particle-free environments. This includes operation rooms, intensive care units, laboratories and clean manufacturing areas. A version for less challenging applications is also available. It is designed for mounting into different types of walls. It is designed for simple maintenance and cleaning and has the option to check the filter gasket tightness and clogging level.

The CFC-W filter is manufactured from a carbon steel sheet with a powder coating surface finish, signal white RAL9003 gloss 30% as standard. Other RAL colours are 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.
