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 pocket filter insert PFG-Ex is
used as a prefilter or final filter in ventilation and air
conditioning systems to separate fine dusts from
the air. The filter may be used in areas with poten-
tially 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.

Hazardous areas (1999/92/EC)

Zones: 1, 2, 21, 22

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 2.69 m/s, 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.

Incorrect use

 WARNING!

Danger due to incorrect use!

Incorrect use of the filter can lead to dangerous
situations.

Use the filter only in the zones mentioned
above.

Use the filter only with the earth cable in
place.
