Information on the installation manual
This manual enables operating or service personnel
to correctly install the product described below and
to use it safely and efficiently.
It is essential that these individuals read and fully
understand this manual before starting any work.
The basic prerequisite for safe working is to comply
with the safety notes and all instructions in this
manual.
The local regulations for health and safety at work
and general safety regulations also apply.
Correct use
The ducted particulate filter of Type KSFS and
KSFS-...-Ex (explosion-proof construction) is
designed as a filter casing for duct installation. The
filter casing is used to separate suspended particles
from the supply or extract air in ventilation and air
conditioning systems.
Usable filter elements:
For the separation of suspended particles such
as aerosols, toxic dusts, viruses and bacteria
from the supply or extract air.
–
GAL/STA Mini Pleat filter panels
–
MFP-MDF Mini Pleat filter panels (not for
explosion-proof construction KSFS-...-Ex)
–
Mini Pleat filter cells MFC-GAL/STA
For the separation of gaseous odorous sub-
stances and contaminants from the supply and
extract air.
–
Activated carbon filter cells AFC (not for
explosion-proof construction KSFS-...-Ex)
Information on explosion protection
EXPLOSION HAZARD!
Unit components that comply with Directive
2014/34/EU include additional information on the
rating plate.
The filter may be used in an area with the poten-
tially explosive atmosphere of zones 1, 2 and 21,
22.
Explosion protection labelling:
II 2G Ex IIC T6 Gb
II 2D Ex IIIB T80 °C Db
Conformity in accordance with guide-
lines
2014/34/EU
Equipment group (2014/34/EU)
II and III
Equipment category (2014/34/EU)
2G and 2D
Ex-areas (1999/92/EC)
Zones: 1, 2, 21, 22
The filter casing, filter chamber cover and the filter
frame must be connected to the earth potential. All
conductive and dissipative parts must be connected
together and grounded.
Conductive dusts are excluded from the application.
Under no circumstances should metallic foreign
materials enter the filter.
Further operating instructions and explosion protec-
tion documents in the sense of the guideline
1999/92/EC, as well as the industry-usual guide-
lines for use, handling, maintenance and disposal of
air filters for ventilation and air conditioning systems
SWKI 2003 and VDI 6022, must be followed.
Airflow velocity and nominal volume flow rate
During proper use and compliance with the nominal
volume flow rate, an airflow velocity of 3.36 m/s is
usually not exceeded on the filter medium, even if
the filter has reached the maximum final differential
pressure. As a guideline for the dimensioning, the
specific maximum air flow rate of 0.2m³/s per m² of
filter area is used.
Compliance with the nominal flow rate must be
ensured by test and monitoring devices within the
system (e.g. pressure differential monitors or flow-
meters).
It is important that you comply with any national
hygiene regulations during installation, commis-
sioning or use.
