Important notes
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.
Safety
Correct use
The explosion-proof filter insert MFI-Ex is used as a
prefilter or final filter in ventilation and air condi-
tioning systems to separate fine dusts from the air.
The filter may be used in areas with potentially
explosive atmospheres, namely zones 1 and 2 as
well as 21 and 22.
The filter must be connected to the earth. All con-
ductive and electrostatic dissipative parts must be
interconnected and connected to the earth.
Do not use the filter for conductive dusts. Make
sure that no metal particles can get into the filter.

Other procedural instructions and documents
related to areas with potentially explosive atmos-
pheres as defined in directive 1999/92/EC as well
as the industry-specific guidelines for use, handling,
maintenance and disposal of air filters for ventilation
and air conditioning systems SWKI 2003 and VDI
6022 also apply.
Airflow velocity and nominal volume flow rate
If the filter is used correctly and if the nominal
volume flow rate is maintained, the airflow velocity
on the filter will usually not exceed the maximum
airflow velocity (see technical data), not even when
the final differential pressure is reached.
Use test and monitoring systems, e.g. differential
pressure monitors or flow meters, to ensure that the
nominal volume flow rate is maintained.
