Description
The clean filtering cassettes for clean areas are intended for filtering the air supplied into areas with high requirements for hygiene and dust-free environment, such as operating rooms, intensive care units, laboratories, dust-free manufacturing areas etc. It is possible to install filters that have a filtration class up to H14 with rubber sealings or gel gaskets into the filtering cassettes for the highest possible tightness.
The design range enables clean filtering cassette selection
• for mounting into different types of ceilings as well as walls.
• for narrowed-down ceiling spaces with a clearance height of 300 mm.
• for horizontal and vertical supply air ducts.
• for less challenging applications with lower price requirements.
• for the highest requirements for supply air cleanliness and airtightness of the ventilation elements.
• with front panels with diffuser functionality and ventilation grilles with different air flow patterns for installation heights up to 4m from the occupied zone.
• with an option to check the filter tightness and clogging level by measurement, with a simple maintenance.
Design
All the clean filtering cassette types are manufactured from a steel sheet with a powder lacquer surface finish, white RAL9010 gloss 30 as standard. 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.
Type B's (basic) joints in front of the filter are spot point welded, which means they are, from the tightness perspective, sufficient for applications that do not require absolute tightness.
