5.Technical description
5.1.Unit description
The dust extraction unit is designed for the collection of mineral, metal and other dry fine
and coarse dust in the air.
mounted on chassis, complete and ready-to-use
quick relocation possible
galvanized tandem chassis with hit brake, TÜV approved
electronic control unit with various special functions
robust construction, designed for continuous operation
recoverable filter system (automatic cleaning during operation)
dust bunker to collect fine and coarse dust
HEPA-Filter stage
high air flow velocity at the inlet side to prevent deposits in the suction line
differential pressure monitoring for filter control
Manual speed control
5.2.Options
Automatic control SRE
Dust bunker with fill level monitoring and emptying via suction connection
5.3.Filter system
The collected fine dust is deposited on the filter surface and forms the “filter cake” (coat).
An automatically working Jet-cleaning system ensures the cleaning of the filters during
operation. The injection nozzles pull air by a suction effect and jet the coat off the filter,
working from inside to the outside. The blown off dust is collected in the dust bunker and
can be removed from there.
5.4.Filter cleaning
The cleaning operates automatically when the compressor and the cleaning are switched
on. The compressor fills the pressure accumulator, which operates the Jet-cleaning
system.
The Deduster is provided with an integrated compressor for short term uses. In
case of long term uses, it is essential to use the external compressed air supply!

6.Initial operation
The Mobile Deduster ME12 is supplied ex works and is in a ready-to-use state.
In case of visible damages, do not operate the unit. Please contact deconta GmbH
immediately.
Determine the location of the Deduster. Choose it close to the working area to avoid
unnecessary long hoses and loss of power.
Connect suction line of Deduster to working area.
Establish power supply to Deduster (400V 32A 3N PE)
Switch on Main switch, make sure the Lamp „Mains Ok“ lights up
Switch on „Fan“ („Fan active“ lights up) and wait until the motor is running
Switch on „Cleaning“ („Cleaning active“ lights up). When an external Compressor is
connected the lamp “Compressed air external” lights up.
The unit is operating!
The desired performance can be set, by turning the rotary knob „Fan control“.

6.1.Option automatic control SRE
The main task of the control unit is to measure and to control the required negative
pressure in the working area.
Specify the measuring point in the working area and connect to the connection
negative pressure with PE-hose 8 x 1
Determine the measuring point in the clean area (adjoining rooms) an connect to
the connection atmosphere with PE-hose 8 x 1

Manual operation:
In manual operation, the „+“ and „-“ keys are used to set the fan performance. The
display show the performance value in „%“ and the measured negative pressure.
Automatic operation:
In automatic mode, the set point in Pascal for the negative pressure is preset with the
keys „+“ and „-„ (display set value in automatic mode). By comparing the entered set
point value with the permanently measured current actual value (measured negative
pressure), the speed of the fan is automatically adapted, that is, the fan moves
automatically „up“ and „down“.
Important:
In the event of power failure, the control saves the last set values, restarts automatically
after damage elimination and restores the saved data.

7.Maintenance
Maintenance work, including changing/removing filters, may only be carried out by
authorised persons wearing suitable protective clothing.
The appliance must be completely disconnected from the power supply during all repairs
and maintenance work.
We expressly refer to possible additional regional and national regulations in the
maintenance of the appliance technology.
The air-conditioning systems (dust extraction unit, industrial vacuum cleaners and
devices used for venting or negative pressurisation) must be serviced as required, at
least once a year, and checked by a qualified technician. The test result shall be
presented on request.
7.1.Details on filter change
The frequency of the filter change depends on the degree of contamination of the filters.
As the filter occupancy is increased (contamination of the filters), the air performance
decreases.
For filter monitoring during operation, there are two manometers installed on the device.
We recommend a filter change when the “max” mark has been reached.
Important: Only use approved, flawless filters!
7.2.Regular maintenance
Check for air tightness
Check solenoid valves function properly
Check oil level of compressor
Regularly emty dust bunker
After the end of work, release overpressure in pressure accumulator by moving the hand
gear.
