2 Introduction
In recent years, a special type of welding fume extraction systems has become an ever more
prominent factor: Filtering of welding fumes and return of the filtered air into the workshop area.
This shows that the issue of environmental consideration has turned for the better for all concerned.
There never has been any doubt about the existence of harmful fumes at welding sites. However,
type of fumes depends on the particular welding process and welding technique. One can generally
differentiate between gases and fumes. The fumes could also be referred to as fine dust.
Investigating them under the microscope, we are able to see particles of a size that will pass
through the respiratory tract deep into our lungs. The size of these particles is a small as 0.001 mm
or even less.
Ventilation is the general approach to improve the conditions at the relevant work positions.
Generally, this is effected by continuously exchanging the air in the workshop, i.e. the total air
volume is exchanged at a high rate. This method will reduce the concentration of harmful particles
within the hall to a great extent, however, it will improve the air within the breathing range of the
individual welder to a negligible portion only.
This also applies to overhead suction systems, i.e. the installation of large extraction hoods
overhead of welding places. Here again the heavily polluted air passes upwards through the
breathing range of the welder. Extraction and/or filtering take place overhead and outside the range
of the welder. A point-attack extraction of the welding fumes right at their place of origin is far more
effective than room ventilation or overhead extraction. Both capital investment for on-the-spot fume
extraction as well as the operating costs for such systems are far below those of the previous
conventional solutions.
Environmental and work protection measures are prerequisite for the successful application of
advanced welding technologies, aside from the optimisation of such welding processes. In view of
increased awareness of the problems involved and in compliance with pertinent legal directives, the
danger potential for personnel and environment must be considered at an early stage and it must
be minimised using appropriate technical solutions.

3 Intended use / Functional principle Weldability – ProtectoReclenz
The filter unit is especially used to extract and filter fumes and dusts. The filter unit is among other
things suited to separate fumes generated when working on steels and complies with the highest
welding fumes class “W3” according to DIN EN ISO 15012-1.
An improper use of the device and of live components can cause damages of
single elements up to dangers to life and limb!
The unit must not be used to extract welding fumes containing oil, explosive dusts and
gases, hybrid mixes, burning or glowing substances, gases, water etc. Furthermore, the
unit must not be used in explosive zones (If in doubt, contact the manufacturer!).
The polluted air is extracted via the suction hood (or a specific suction head) and directed into the
suction arm (or suction hose) and into the filter unit. Here, the particles are collected on the surface
of the filter cartridge. The clean air passes the fan and returns into the room via the exhaust grid
Pos.31).
Caution:
As soon as the accumulated dust particles on the filter cartridge yield a maximum resistance to the
air flow, the integrated electronic control will illuminate the red lamp of the air flow volume control
(Pos.4) and the signal horn (Pos.5) sounds up.
The filter cake is removed by manually by directing the air jet of a compressed air pistol onto the
filter area.
(Refer to chapter 7.1 ‘Cleaning of filter cartridge)
The removed filter cake is gathered in the dust collecting bin from which it can be taken for final
waste handling. (Refer to chapter 7.3 ‘Emptying of the dust collector bin’)

•At regular intervals inspect the mains supply lead for signs of damage !
•The unit must not be used when there is any damage or irregularity at the mains supply
lead !
•Use only dry and oil-free compressed air with pressure ratings from minimum 3 bar to 4 bar
maximum.
•Reposition the suction arm during welding operations, if possible by exploiting the thermal
flow of the welding fumes
•The maximum permissible distance of 25 cm to the welding point should not be exceeded.
•Do not use the filter unit when any one or more components of the system are defective,
missing or damaged. In any one of these instances contact the Weldability Service
Department: Phone: [phone]
•When extracting carcinogenic welding fumes as from the processing of nickel or chrome
alloys, the requirements of the directives on clean air of the German TRGS 560 ‘Return of
process air when working with carcinogenic media’ must be observed. (And/or the
equivalent national directives for the respective user.) The suction unit ProtectoReclenz has
been checked and approved by the Institute for Work Safety (BGIA) under the certification
number xxxxxx. This certification is part of the operating instructions.
•Further information regarding the TRGS 560 can be obtained from the
‘BGIA - Berufsgenossenschaftliches Institut für Arbeitssicherheit’
(Institute for work safety of the employers’ liability insurances) at
D-53754 Sankt Augustin, Germany.

5 Initial operations
The filter unit is delivered in a state ready to be plugged to the mains supply.
Prior do using the machine, the extraction/suction elements, e.g. the suction arm and appropriate
optional accessories, must be mounted or installed.
5.1 Mounting of suction arm
Attach the suction element (Pos.6) e.g. the suction arm or the connecting piece and clamping
flange (Pos.29), screws (Pos.27) and spring washers (Pos.28).
Caution:
The connecting element must move/turn freely !

5.2 Electrical connection
•Connect the filter unit to the mains supply. (Observe the information on the type plate!)
•When you switch the unit on for the first time, make sure that the fan rotor turns in the
required direction. This can be detected in case of a weak extraction performance. An
adhesive label is fixed within the fan housing for a visual inspection. In case of connections
of 400 V or 500 V, it is possible that the set rotary field is incorrect and needs to be
changed.
Attention:
The warning label „Disconnect the unit from the mains supply before opening the housing“ is only to be
ignored in exactly this case. Open the door when the unit is switched off, but do not reach into the fan
housing at any moment. Now switch the unit switch switch on for a short time and then switch it out.
The fan starts operating slightly and it is now possible to compare the sense of rotation to the label.
Wait until the fan has stopped to shut the door with the help of the cap nuts.
If you have any further questions, please contact our after-sales team: Phone: [phone].
Please note:
It is possible that the sense or rotation has to be checked every time the device is connected to another
mains connection.
Only authorized electricians are allowed to carry out tasks in the electrical field!
6 Explanation of the controls
Pos.1 The main switch switches the filter unit on or off.
Pos.2 The operating hour counter starts to count as soon as the filter unit will be switch on.
Pos.3 The operating status lamp shows if the filter unit will be switch on.
Pos.4 + 5 The red volume control lamp (Pos.4) illuminates and the signal horn (Pos.5) sounds,
when the suction power is no longer adequate. Now the filter inserts must be cleaned
manually (Refer to chapter 7.4: ”Change of filter cartridge”).

7 Maintenance and service
The accumulation of extracted particles on the filter cartridge will eventually lead to a reduction of
the suction / extraction performance.
The rate of accumulation and thereby the degrading of the filter cartridge (Pos.11) is monitored
electronically. In order to maintain the designed suction performance, the filter cartridge must be
cleaned when the red volume control lamp (Pos.4) illuminates and/or the signal horn (Pos.5)
sounds. (Refer to chapter 7.1: ”Cleaning of filter cartridge / Manual cleaning”)
The accumulated dust particles are blown off the filter by applying compressed air from the clean
side. The released filter cake will drop into the dust collecting bin (Pos.17). (Refer to chapter 7.3:
”Emptying of dust collector bin”)
The useful service life of the filter cartridge greatly depends on the operational environment. For this
reason, it cannot be predicted.
If the operating pressure of the filter unit should not be achieved after cleaning the filter cartridge,
the cartridge must be replaced. (Refer to chapter 7.4: ”Change of filter cartridge”)
Caution:
Stop the operation of the filter unit when changing the filter cartridge.
Exchange of the filter cartridge and the disposal of the element may be executed only in amply
ventilated environments and when using an appropriate protective respiratory mask!
We recommend to use a respiratory mask to DIN EN 141/143 - Protection class P3. It is also
recommended to use appropriate protective gloves.
Dispose of the filters according to the legal regulations. The polluted filter elements must be put in
an appropriate container (e.g. PE bag), bags are available as an option (see list of spare parts)! We
recommand to stockpile some PE bags in time.
The task of changing the filter elements should be executed by trained personnel only!
7.1 Cleaning of filter cartridge
When the red volume control lamp (Pos.4) illuminates and the signal horn (Pos.5) sounds, the filter
cartridge must be cleaned according to the following procedure:
•Disconnect the filter unit from the mains supply (Pull the plug) !
•Close the throttling flap at the suction hood.
•The front doors of the housing (pos.10 + 16 + 21) have to be closed.
•Open the cleaning access door (Pos.22) by releasing the overcentre lock (Pos.34).
•Evenly apply the air jet from the compressed air pistol (available as an option) to the filter
cartridge (Pos.11). (Refer to chapter 6.2. “ Compressed air supply”)
•Apply the air jet for ca. 5 – 10 minutes.
•Close the cleaning access door (Pos.22) and secure it with the overcentre lock (Pos.34).
•Open the throttling flap at the suction hood.
•Connect the filter unit to the mains supply.
•(Observe the information on the type plate!)
Caution:
Without the compressed air supply, the filter cartridge will be clogged, and its performance will
degrade rapidly. The unit will indicate a fault (Filter clogged/full) !
Do not manually shake or wash the filter element as this will damage the filter medium, and the
harmful waste particles will be returned into the workshop's atmosphere !
