3.2 Functional description
The DUSTOMAT is equipped with a three-phase motor that drives a radial fan.
The main switch supplies or cuts off the necessary power to the device, and the
fan is turned on and off from the control unit. The device starts running as soon as
the main switch is turned on.
The vacuum created by the fan draws air through the suction pipe or hose
connected to the intake port. A permanent filter set up within the filter housing
separates the dust that is in the exhausted air. The purified air is guided draft-free
back into the room through the exhaust openings on the top of the device.
With the filter cartridges used, the device is equipped with a vacuum monitor as a
control device for overseeing minimum airflow volume. This monitoring device
measures the vacuum in the filter. With increased dust soiling of the filter, the flow
resistance increases along with the vacuum behind the filter.
If the value set on the vacuum monitor is reached, the filter cartridges are
automatically cleaned with compressed air. A pneumatic jet pulse cleaning device
is integrated for this purpose. Intense pulses of compressed air are successively
introduced into the filter cartridges. The cleaning frees the filters of dust and
reconditions them. The dust collection container underneath the filter catches the
dust that is cleared.
For easy disposal of the collected dust material, the dust collection drawer is
released, pulled out and removed from the dust collection container complete with
contents.
The device is equipped with a pre-separator / baffle. This pre-separator / baffle is
built in behind the intake port, before the actual pre-filters. It pre-separates the
coarse particles and thus prevents them from being sucked against the filters. The
pre-separator / baffle must be checked regularly for contamination. For this, follow
the safety instructions for cleaning.
3.3 Monitoring the minimum airflow volume
The minimum airflow volume is monitored though a differential pressure
measurement. Capture elements with various exhaust port diameters can be used
with the device. Here it should be ensured
that suction does not go below the minimum airflow volume
- This minimum airflow volume depends on the capture element’s port
diameter and the required flow velocity.

4. Safety instructions
4.1 Hazard classes
Safety instructions and cross-topic information are indicated in this manual by
symbols.
Based on the severity of the hazard, the hazard warnings are categorized as
follows:
DANGER
Hazard warning about an immediate danger to people.
Failure to comply can lead to severe injury or death.
WARNING
Warning about a recognizable hazard.
Failure to comply can lead to severe injury or death, and can destroy the device or
parts thereof.
CAUTION
Instruction about a hazard.
Failure to comply can lead to mild injury and to damage to the device.

4.2.1 Symbols on the device
Turn the device off.
Wait 5 minutes.
Then pull out the dust collection drawer or open the device.
Before commissioning, read and observe the operating manual and safety
instructions (per ISO 11684)
Hand injury warning (per BGV A8 W27)
Short-term loads on the surface must not exceed 175 kg!
Do not take in glowing dust or other sources of ignition. Do not use with
machines that produce sparks!

12 MOBEX P 09831-52-02
4.3 General safety notes
During exhaust, the volume flow returned from the dust extractor into the room
must be no more than 50% of incoming air. With free room ventilation, the
incoming airflow must equal the room volume every hour. This means that the rate
of air replacement must be once per hour.
Incoming airflow [m³/h] = room volume [m³] air replacement rate [1/h]
Example:
When the dust extractor is operating at the nominal airflow volume of 1060 m³/h
the same volume of fresh air must therefore be fed in. This occurs with natural
ventilation if the volume of the work room is 1060 m³ (e.g. 353 m² surface with a
3m ceiling height).
According to work equipment user directives 2009/104/EG and TRGS 560, safety
devices for prevention or removal of hazards must be regularly maintained and
regularly inspected by an expert for safe, flawless operation.
In all emergencies, the device must be disconnected from the power supply
immediately. Turn the device off with the main switch and pull the plug.
If there is a fire, alert the fire department immediately, and contain the fire by
appropriate means! Therefore keep a suitable extinguishing agent near the device
before start-up and during operation.
4.4 Preventing mechanical hazards
WARNING
Crushing hazard due to loose or open covers
Keep covers closed during operation!
All movable machine parts driven by electric motors must be covered by fixed,
securely fastened protective covers that can be removed only with tools.

09831-52-02 MOBEX P 13
4.5 Preventing electrical hazards
DANGER
High-voltage electric shock
Follow the safety rules for working with electrical devices!
Secure the device with a padlock against reactivation!
Cut off the device's power supply by pulling the electrical plug!
Work on the electrical grid and on voltage conducting parts must be done
only by an electrical specialist.
DANGER
High-voltage electric shock due to damaged power cable
Do not damage by running over, crushing, straining, etc.
Regularly check the power cable for damage and ageing.
Do not use if damage has been found on the power cable!
Work on the electrical grid and on voltage conducting parts must be done
only by an electrical specialist.
Use only original ESTA replacement parts.
DANGER
High-voltage electric shock due to working at the running device
Turn off at the main switch and secure with a padlock against reactivation!
Cut off the device's power supply by pulling the electrical plug!
Work on the electrical grid and on voltage conducting parts must be done
only by an electrical specialist.
DANGER
Residual hazard from loose or open covers
Keep covers closed during operation!
Work on the electrical grid and on voltage conducting parts must be done
only by an electrical specialist.
All electrical parts must be covered by fixed, securely fastened protective covers
that can be removed only with tools. The device complies with Protection Class I
according to EN 60 335.
After use, before moving the device to another site and before cleaning,
maintenance, or replacement or removal of movable parts, the device must be
turned off at the main switch and the electrical plug must be pulled.

14 MOBEX P 09831-52-02
4.6 Preventing dust hazards
CAUTION
Damage due to dust release
Maintenance, cleaning, repair and emptying must be done only by expert
personnel.
Wear personal protective gear.
- Respirator mask (particle filter class P3)
- Protective clothing
- Safety gloves
Set up locally filtered forced-air ventilation when the device is being
maintained, inspected or cleaned.
Operate the device only with the complete filtration system.
During transport, close the intake port dust-free with sealing plugs.
CAUTION
Damage due to dust build-up in the pipe system
Regularly check the connected pipe system for dust build-up.
Observe the minimum air speed for your application and the resulting
minimum airflow volume.
When emptying the dust collection bag, it is possible to inhale
dust. Therefore all repair, cleaning and maintenance procedures,
including removing and emptying the dust collection container,
must be performed by expert personnel using personal protective
gear.
The people assigned to cleaning work must be instructed on the
aspirated toxic materials. Negative impacts on uninvolved persons
and the environment must be prevented. Clean the maintenance
area thoroughly after maintenance is finished.

09831-52-02 MOBEX P 15
4.7 Preventing hazards - Noise
CAUTION
Danger of hearing damage from release of compressed air impulses when filter
elements are being cleaned
Keep the device's covers closed.
Wear ear protection.
Open the device only when the compressed air tank has been relieved.
To do this:
- Turn the device off at the main switch.
- Wait for automatic post-cleaning to end,
- Cut the compressed air supply directly at the control cabinet
- If necessary, empty the compressed air tank through "Start Cleaning".
Open the device only when it has stopped.
To do this
- Cut off the power supply by pulling the electrical plug
If the device — especially the cleaning module — must be opened during
operation, during normal operation automatic cleaning can be triggered through
the controls. The cleaning impulse can damage human hearing. The manometer
attached to the compressed air tank is for checking the tank’s pressure.
After use, before moving the device to another site and before cleaning,
maintenance, or replacement or removal of movable parts, disconnect the device
at the control cabinet.
