3Description
3.1Function
FlexPAK 800/1000 DX is a complete vacuum unit with
a direct driven side channel fan fitted as one unit on a
steel frame and a start and control unit with an integ-
rated 24 V transformer. The unit is controlled by a fre-
quency converter, has automatic start/stop, and auto-
matic filter cleaning.
3.1.1Filtration in two stages
FlexPAK 800/1000 DX filters particles in two stages.
In the first stage, coarse particles are separated away
in the inlet. In the second stage, fine particles are sep-
arated away by filter bags, see Figure9.
3.1.2Automatic filter cleaning
FlexPAK 800/1000 DX uses filter cleaning by a short
blast of reversed airflow with atmospheric pressure.
By the rapid opening of the Filter Cleaning Valve (FCV)
located on top of the filter, a powerful blast of re-
versed airflow is created, efficiently dislodging dust
from the filter bags, see Figure8.
3.1.3Control filter
The unit is equipped with a control filter, see Fig-
ure4B, item 16. The control filter filters the air after
the main filter to ensure that no material continues
to the suction source in case of a main filter break-
age. The control filter functions as a safety device and
does not increase the filtration efficiency.
The pressure drop over the control filter is monitored,
and a signal is sent to the control unit if the pressure
difference reaches the set value. The pressure differ-
ence is preset at 4 kPa /40 mbar / 0.58 PSI.
3.2 FlexPAK 800/1000 DX and ATEX
3.2.1Area classification
FlexPAK DX is designed to extract combustible and
non-combustible dust, but the unit “as a whole” is not
to be placed in an area that is classified as a zone ac-
cording to directive 1999/92/EC. It is only the inside of
the filter that meets ATEX requirements.
FlexPAK DX may be used with duct systems internally
classified as zone 20, 21 or 22.
The product has no marking since there is no in-
ternal ignition source. The inside is to be considered a
simple filter/silo and does not fall under the scope of
the directive 2014/34/EU.1

EN 3.2.2Permitted materials
WARNING!Explosion risk
• Do not collect material that may cause igni-
tion or blocking. It is strictly prohibited to col-
lect material that may undergo dangerous
chemical or thermal reactions and/or self-ig-
nite.
• Do not make any changes to this product
without consulting Nederman. Adding a relief
duct or changing the spacing or length of fil-
ter elements affects the calculations accord-
ing to EN 14491.
• The filter should not be used for filtering
fumes from welding processes.
WARNING!Risk of personal injury
Use suitable protective equipment: goggles,
ear protection and a protective mask.
It is of the utmost importance to know the
properties of the extracted material.
Some materials may undergo chemical reac-
tions in combination with humidity/water.
Such humidity may, for example, form if the
humidity in the extracted air is condensed in
the filter.
FlexPAK DX is intended to be a part of an extraction
system collecting material with the following proper-
ties:
• MIE (Minimum Ignition Energy): See the product
identification plate.
• MIT (Minimum Ignition Temperature): See the
product identification plate.
• Kst: See the product identification plate.
• Pmax: See the product identification plate.
Materials with properties not within the values stated
above or if a suppression or flameless system is used
are to be investigated prior to use with FlexPAK
800/1000 DX. Contact Nederman for technical sup-
port and dust application investigation.
3.3Explosion protection
The CE and ATEX markings on this unit ensure both a
high level of safety and protection against ignition of
the collected combustible dust. However, if an explo-
sion occurs due to misuse, insufficient maintenance or
faulty installation, this unit is equipped with addition-
al protection methods to avoid dangerous pressure
build-up in the filter.
FlexPAK 800/1000 DX is equipped with one of the
following protection systems.
• Explosion venting, see Figure2A.
• Explosion suppression system, see Figure2B.
• Flameless venting.
3.3.1Explosion venting
The risk area may extend beyond the values
given above. The final risk area is to be evalu-
ated with regards to affecting factors found in
Standard EN 14491.
For assistance and information, contact Neder-
man.
The harmful effects of an explosion are minimized
by venting the pressure and flame of the explosion
through an explosion relief panel, see Figure2A. In
case of an explosion, the resulting flame and pressure
escape through the explosion relief panel which is to
be directed towards a safe area without any people.
This area is referred to as the ‘risk area’.
The risk area is to be clearly marked, for example with
a fence, warning lines and signs, and entry is prohib-
ited when the filter is in operation. The area is to be
free of any flammable or combustible material or oth-
er objects which may be damaged by the flames and
explosion pressure.
The general size of the risk area is shown in Figure3.
The following dimensions apply:
• A = 10 m (32.8 ft)
• B = 5 m (16.4 ft)
3.3.2Explosion suppression system
With an explosion suppression system, the early stage
of an explosion is detected with optical and/or pres-
sure-sensitive devices, and an extinguishing agent
is quickly dispersed into the filter, see Figure2B The
suppression of the explosion is initiated an extremely
short time after detection of the explosion (in mil-
liseconds) and stops the pressure rising and extin-
guishes (suppresses) the flames of the explosion.
This ensures that the filter is not stressed to a danger-
ous level by the explosion.
The key components of the explosion suppression
system are the following:
• An explosion detection device (optical/pres-
sure-sensitive).
• A computer-operated control unit.
• Action elements such as pressure cylinders contain-
ing an extinguishing agent with an extra fast open-
ing valve.
Detailed information regarding system installation,
function, operation and maintenance can be found in
the suppression system manual.
3.3.3Flameless venting
The method of flameless venting is similar to method
1 “explosion venting”. However, a device attached to
the outside of the vent will stop flames from exiting
the filter vessel. Such a device is sometimes referred
to as a “quench-device” or “flameless-device”.
