FUMEX ME EX
2.5 General warnings and
information
The product must not be modified.
The product may only be used in perfect
technical condition and according to its
intended use as described in Section 3.3
Area of use. Faults that may compromise
safety must be rectified immediately.
The product’s moving parts always constitute
a risk (e.g. cutting, clamping or gripping points).
The product is not intended for the extrac-
tion of non-conductive dust with an MIE
(Minimum Ignition Energy) of less than 4 mJ.
The product must not be used in environ-
ments containing substances that can affect
or react with the materials from which it is
made. See 10.1 Technical data.
The earth cable must be connected to the
appropriate earthing point.
The earth cable resistance must not exceed
10 Ω.
For maintenance work where contact with
dust occurs, personal protective equipment
such as safety glasses, respiratory protection
and safety gloves must be worn.
The product should only be used by personnel
with good knowledge of the product and its
area of use.
Please note that the facility owner is
responsible for the classification and zoning
of the workplace.
Waste disposal must be carried out in
accordance with applicable national legislation.
2 Safety
2.1 General
This product is safe to use and designed to minimise
any potential risks. Even so, if the product is not used
correctly or as intended, it may be hazardous to the
user or cause damage to the product. The user should
therefore be informed and trained to handle the pro-
duct’s safety features.
2.2 Warning levels (on product)
Safety signs on Fumex products make use of colour
codes and signal words in accordance with ISO 3864-2.
Red (DANGER): used to indicate
an imminently dangerous situation
which, if not avoided, will result in
death or serious personal injury.
Orange (WARNING): used to indicate
a potentially dangerous situation
which, if not avoided, may result in
death or serious personal injury.
Yellow (CAUTION): used to indicate a
potentially dangerous situation which,
if not avoided, may result in moderate
or minor personal injury.
2.3 Safety signs
Refer to 3.2 Labels and safety signs.
2.4 Protective equipment
As the extraction arm is earthed, electrostatic discharge
can be experienced when touching the product.
People can become electrostatically charged either
directly (friction from clothes or shoes) or by induc-
tion (proximity to highly charged objects). Electrostatic
charges can be produced when a person walks across a
floor with a high resistance. This can usually be preven-
ted with the use of floor coverings with a resistance to
earth of less than 100 MΩ and the use of electrostatic
dissipative shoes.

Manual
FUMEX ME EX
3.3 Area of use
Since the product does not have an internal
ignition source, it cannot be classified under
the ATEX directive 2014/34/EU.
The ME EX extraction arm is designed for the safe
extraction of gas and dust in explosive atmospheres.
The product complies with the requirements of the ATEX
directive for category 2 equipment for gas and dust, and
it is suitable for use in zones 1 and 21 as well as 2 and 22.

3.5 Function
The ME EX extraction arm is an extractor arm for
capturing and extracting gases and dust-filled air in
explosive atmospheres.
The extraction arm’s swivel (8) rotates a full 360° and
can be mounted on a table, wall- or ceiling bracket (9).
The arm is fitted with a torsion spring (inside the joint)
or gas springs (7) to counterbalance the weight of the
arm. The joint friction (2) can be altered with the tension
knob (5) found on each joint. An adjustable damper (3)
is used to completely block or adjust the airflow. Each
bracket comes with an earth cable (10) to be connected
to the earth at the facility.
For hoods and brackets, see Chapter 11 Accessories &
Spare Parts.

5 Commissioning
5.1 Start-up
1. Check that all joints are adjusted to the correct
friction.
2. Check the suction tubes for foreign objects.
Remove any such objects immediately.
3. Check the resistance of the extraction arm with a
calibrated ohmmeter. See Fig. 12. The resistance
between the measuring points must be less than
1 MΩ.
4. Check the earth resistance with a calibrated ohm-
meter. See Fig. 13. The resistance between the me-
asuring points (earth plane/product) must be less
than 1 MΩ.
6 Operation
Ensure that any objects or people that may
be electrostatically charged cannot come into
contact with the equipment.
When extracting different dust combinations,
first ensure that the combination itself is not
an ignition hazard, such as iron filings and
aluminium dust.
Avoid causing an electrostatic charge on
non-conductive dust.
Avoid hygroscopic dust and dust that risks
sticking to the product.
Caution must be exercised with hybrid gas/
dust mixtures as they may prove more
flammable than the separate gas and dust
safety data indicate.
The extraction arm is easily positioned within
the work area by hand. For the best result,
the suction nozzle should be positioned as
close to the contaminant source as possible,
and the result can be further improved if
the suction nozzle rests on a surface
(the so-called Coanda effect).

TROUBLESHOOTING GUIDE
Symptom Possible cause Recommended action
1. Difficulty moving the extraction
arm into the desired position.
Friction joints incorrectly adjusted. Adjust the tension.
Friction joints worn. Contact your dealer to replace the friction rings.
7 Troubleshooting 7.1 Troubleshooting guide
The troubleshooting guide contains information for
identifying faults which are simple to rectify. Always
perform the troubleshooting procedures before
contacting FUMEX.
8 Maintenance
Please remember that only original spare
parts may be used.
Make sure that all moving parts are secured to prevent
unintentional movement.
8.1 Cleaning
Consider the risk of electrostatic discharge
from your person or cleaning tool when
removing dust deposits.
Cleaning must be performed when the atmosphere is
not potentially explosive. When dust with an MIE of less
than 30 mJ is being extracted, personnel should wear
electrostatic dissipative shoes and clothing.
To avoid damage, the product should be cleaned with a
clean cloth dampened with a neutral detergent.
8.1.1 Dry cleaning
Vacuum and dry the product inside and outside.
MAINTENANCE SCHEDULE
Interval Item Inspection module Maintenance instructions Date
As
necessary

8.1.2 Wet cleaning
Check that the detergent is neutral and will
not affect any of the materials from which
the product is made. See the material
specification in Section 10.1 Technical data.
Allow the equipment to dry before use.
8.2 Maintenance schedule
Depending on the changing operating
conditions between the different systems,
the intervals for recommended maintenance
may differ. Users should therefore determine
their own maintenance intervals.
The checklist for maintenance is designed for normal
use of the product. The recommended intervals are
approximate and refer to the time after the first start-up.
FUMEX recommends the following maintenance
schedule:
