These operating instructions are a part of the equipment. The
manufacturer reserves the right to change performance-, spe-
cification- or technical data without prior notice. Please keep
these instructions for future reference.
1.1 Intended Use
The filters may be used in a gas analysis system to filter
sample gas.
Filters AGF-VA-23 and K-AGF-VA-23 may further be used in ex-
plosive atmosphere areas zone 1 and 2, explosion class IIA, IIB
and IIC. When used for this purpose, the information in
chapter "Use in explosive atmosphere areas" must be fol-
lowed in addition to the other information in these operating
instructions.
1.2 Scope of delivery
• 1 x Filter
• Product documentation
2 Safety instructions
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.

DANGER
Toxic, corrosive gases
The measuring gas led through the equipment can be hazard-
ous when breathing or touching it.
a) Check tightness of the measuring system before putting
it into operation.
b) Take care that harmful gases are exhausted to a save
place.
c) Before maintenance turn off the gas supply and make
sure that it cannot be turned on unintentionally.
d) Protect yourself during maintenance against toxic / cor-
rosive gases. Use suitable protective equipment.
3 Use in explosive atmosphere areas
Intended Use
Filters AGF-VA-23 and K-AGF-VA-23 may be used in explosive
atmosphere areas zone 1 and 2. Explosion classes IIA, IIB and
IIC are approved. The filters have no innate ignition source
and do not fall into the application of Directive 2014/34/EU
and therefore do not bear the CE mark.
II 2/2G c IIC TX X, -5°C <T
The ambient temperatures must not be below -5 °C or above
60 °C.
The highest surface temperature is directly affected by the
temperature of the medium introduced. The medium intro-
duced must not exceed the maximum temperature of 100 °C.
If necessary, a temperature monitor should be installed.
When operating the filters with moisture detector and con-
troller, these must be inherently safe according to EN
60079-11.
When using a moisture detector, its working temperature
may deviate from those specified here and limit the approved
ambient temperature range of the filter as well as the per-
missible medium temperatures.
Depending on the process conditions, pressure- or flow
sensors may be required for continuous monitoring. If the
process holds a risk of flame propagation a flame arrestor
must be installed.
The approved explosion class of the inner zone varies by the
filter element used. See chapter AGF-VA-23 and K-AGF-VA-23
to match filter element options with explosion classes.
Safety instructions
The following safety notices must absolutely be followed
when operating the filter in an area with explosive atmo-
sphere. Failure to do so can result in an explosion hazard.
• Only perform installation-, removal- and maintenance
work in non-explosive atmosphere.
• Protect filter from mechanical impact. If necessary, install
a cover which withstands at least 4 joule.
• Protect filter from vibration, or avoid vibration. If neces-
sary, mechanically brace supply and discharge lines.
• Observe all limits, operating parameters, etc. specified in
these operating instructions and the data sheet.
