Clean areas
Description
The clean ltering cassettes for clean areas are intended
for ltering 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 lters that have a ltration class up to
H14 with rubber sealings or gel gaskets into the ltering
cassettes for the highest possible tightness.
The design range enables clean ltering 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 ow patterns for
installation heights up to 4m from the occupied zone.
• with an option to check the lter tightness and
clogging level by measurement, with a simple
maintenance.
Information about accessories for CFC is available
on page 9.

Design
Material used
All the clean ltering cassette types are manufactured
from a steel sheet with a powder lacquer surface nish,
white RAL9010 gloss 30 as standard. The structural
joints on the clean ltering cassette casings are
consistently welded to ensure the cassette airtightness
in front of as well as behind the lter.
Type B’s (basic) joints in front of the lter are spot point
welded, which means they are, from the tightness
perspective, sufcient for applications that do not require
absolute tightness.
The sealing areas for the lters are smooth for rubber
sealings for types C, B, R, W. For type G the blade
sealing area is used for the gel gasket.
The lter installation into the clean ltering cassette
and sealing pressure onto the sealing areas for types C,
B, R, W are ensured by 4 thread pressure mechanisms
in the ltering cassette corners. Type G uses 4 spring
mechanisms in the ltering cassette corners.
For a more detailed description, please see chapter
“Mounting” (page 10).
The ceiling ltering cassette types are delivered with two
types of diffuser tting surface designs – the ltering
cassette face in the tting area can be ended either with
an alignment rim (type 1) or without it (type 2).
For the type 2 tting surface, the front panels (diffusers)
are mounted either using one central bolt into the
mounting bridge, or using four bolts in the ltering
cassette corners. More specic details regarding the
tting surface types, their mounting and their purpose
assignment for different installation approaches can
be found in Fig. 8 - 10 and Tab. 1 - 7. The front panels
(diffusers) supplied along with the ceiling ltering
cassettes correspond in type names, parameters and
design with the standard Systemair diffusers.
The wall ltering cassette type is by default delivered
including a ventilation grille NOVA-A.
