3 Use in explosive atmosphere areas
Intended Use
Filters K-AGF-VA-350 and AGF-VA-350 may be used in explosive atmosphere areas zone 1 and 2. Explosion classes IIA, IIB and IIC
are approved. The filter has no innate ignition source and does not fall under Directive 2014/34/EU and therefore does not bear
the CE mark.
II 2/2G c IIC TX X, -5°C <Tamb< +60 °C
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 introduced
must not exceed the maximum temperature of 100°C. If necessary, a temperature monitor should be installed.
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-350 [> page11] and K-
AGF-VA-350 [> page12]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 atmosphere. Fail-
ure 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 necessary, mechanically brace supply and discharge lines.
– Observe all limits, operating parameters, etc. specified in these operating instructions and the data sheet.
– Maintenance and cleaning instructions must be followed.
– When used with moist gasses, a condensate separator must be installed. Moist gasses can clog pores in the filter. Gas pres-
sure building up can result in an impermissible temperature rise.
– Observe the grade of filtration of the fine mesh filter and if necessary install a pre-filtration to ensure larger solid particles do
not clog the filter prematurely.
– Observe the durability list in this document. Only use media compatible with the filter materials.
– Do not repair the filter. Damaged filter components must be replaced.
– Do not paint, laminate or otherwise coat the filters.
– Observe the applicable constructor regulations, e.g. EN 60079-14, for installation and mounting.
– All metallic parts of the filter must be connected to an earth potential. The resistance of a continuity test must not exceed 1
MΩ (1*106 Ω).
– The sealing materials, e.g. Teflon tape, must be conductive so all parts of the filter are earthed. If necessary, install an earth
bridge.
Operation and Control
DANGER Risk of explosive gasses leaking and crossing zones
Check the filter is tight prior to operation.
Inadequately sealed filters can leak. Gas may leak or the ambient atmosphere be drawn
in. Use a suitable method for the leakage test, appropriate for the application.
Service
Please note the following instructions. Failure to do so may result in explosive gasses escaping and crossing zones.
– Check the filter is tight after any maintenance and the intervals specified in the maintenance schedule. Inadequately sealed
filters can leak. Gas may leak or the ambient atmosphere be drawn in. Use a suitable method for the leakage test, appropri-
ate for the application.
– There must be no internal or external Ex atmosphere when performing maintenance. If necessary, flush the filter with inert
gas. Switch off pumps on the gas circuit and close supply and discharge lines.

Service schedule
When using the filters in ATEX areas, follow this maintenance schedule:
Component Interval in operating hours Work to be performed
Filter element Weekly, and depending on the contamination
level of the filter element.
– Visually inspect for contamination.
– If contaminated, replace the filter element and O-ring.
O-ring Every time the filter cover is removed. – Clean O-ring contact surfaces.
– Replace O-ring.
Entire filter Weekly and depending on the external level of
contamination.
– Remove layers of dust with a damp cloth.
Entire filter Every 6 months and every time the filter is
opened.
– Perform a leak test.
When replacing the filter element, the seal must also be replaced.
Cleaning
Dust deposits on the filter must be removed regularly.
Clean the outside of the filter using only a clean, damp cloth (do not use cleaners containing solvents).
DANGER Spark formation due to electrostatic discharge (explosion hazard)
Only clean the filter with a clean, damp cloth.

4 Transport and storage
Only transport the product inside the original packaging or a suitable alternative.
The equipment must be protected from moisture and heat when not in use. It must be stored in a covered, dry and dust-free
room at a temperature of -20 °C to 60 °C (-4 °F to 140 °F).

5 Installation and connection
5.1 Requirements to the installation site
The filter should be installed in a way so the filter element can be replaced. If the filter protrudes from a contour, please note
this poses a risk of damage.
The spacing for the mounting holes (for M6 screws) is 25 mm.
The maximum permissible pressure is 270 bar abs. at temperatures up to 150 °C for models (K-) AGF-VA-350-T, or 200 bar abs. at
temperatures up to 240 °C for model AGF-VA-350-P.
5.2 Connecting the gas lines
The connections must be made carefully and properly using suitable fittings (gas connections right/left and bottom condensate
drain/bypass: NPT 1/4”) and sealant.
When not using the condensate drain/bypass, attach a sealing plug to the thread (sold separately - see appendix).
An arrow on the filter indicates the flow direction. The filter can be screwed onto the mounting bracket to switch the inlet and
outlet side.
Perform a leak test with suitable means.
5.3 Connecting a bypass
A 1/4” NPT connection thread for connecting a bypass is located inside the filter cover.
– Screw in fitting.
– Perform a leak test with suitable means.

7 Maintenance
During maintenance, remember:
– The equipment must be maintained by a professional familiar with the safety requirements and risks.
– Only perform maintenance work described in these operating and installation instructions.
– When performing maintenance of any type, observe the respective safety and operation regulations.
– Only perform maintenance when cool.
– For Ex applications also observe chapter “Use in explosive atmosphere areas”.
DANGER The gas inside the filter, condensate and used filter elements may be caustic or corros-
ive.
Sample gas can be harmful.
a) Before maintenance turn off the gas supply and surge with air if necessary.
b) Exhaust sample gas to a safe place.
c) Protect yourself against toxic / corrosive gas during maintenance. Wear appropriate
personal protection equipment.
7.1 Replacing the filter element
CAUTION Gas leakage
The filter should not be dismantled under pressure.
Don’t use damaged parts again.
– Depressurise the system and flush the filter with air before opening.
– Unscrew the filter bowl from the filter head counter-clockwise.
– Unscrew the support tube with filter element from the filter head.
– Pull the filter element off the support tube and attach a new element.
– Screw the support tube with filter element hand tight into the filter head. The self-sealing is achieved through light contact
pressure of the filter element at the front. Avoid excessive seating stress.
– Check the O-ring on the filter bowl and replace if damaged. Screw the filter bowl hand tight onto the filter head.
– Perform a leak test with suitable means.
NOTICE!Please observe legal regulations when disposing of filter elements.

Important note
The tables headed "Chemical resistance of plastics" and "Properties of plastics materials" have been compiled from information
from various producers of raw materials. The figures relate exclusively to laboratory tests on raw materials. Plastics items made
from these materials are often subject to influences which cannot be detected in a laboratory test (temperature, pressure,
stresses in the material, chemical substances, design features, etc.). For these reasons the figures quoted can serve only as a
guideline. In case of doubt we strongly recommend that a test be carried out. No legal claims can be derived from these figures
and we disclaim all liability. The chemical and mechanical resistance of a product does not suffice for the assessment of its suit-
ability for use, for example legislation on flammable liquids (explosion protection) is to be taken into particular consideration.
Chemical resistance for other substance on request.
