1 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 posi-
tions. 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 concentra-
tion 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 applica-
tion of advanced welding technologies, aside from the optimisation of such welding pro-
cesses. 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 solu-
tions.

2 Intended use
2.1 Intended use
The Airfilters MINI are exclusively for the purpose of suction of gases and fumes, which are
contaminated with harmful substances and which occur in the following areas of activity:
– Soldering in the electronics industry,
– Laser processing,
– Dental and medical technology,
– Dermatology,
– Catering and
– Hairdressers.
An improper use of the device and of live components can cause damag-
es 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!).

3 Safety instructions
The following basic safety measures must be observed to prevent of electric shocks, injury or fire
when using electrical devices:
•Read and follow the instructions listed below before using the filter systems !
•Store the operating and service instructions in a secure and readily accessible space !
•Protect the connecting lead from heat, wetness, oils and sharp edges !
•Confirm the correct voltage. (Refer to the unit type plate)
•Use only original TEKA spare parts !
•Do not operate the unit without a filter cartridge installed !
•Pull the mains plug before opening the unit !
•The exhaust gird must not be obstructed or blocked in any way!
•Always take care that the unit stands secured and that the caster brakes are set !
•Pull the mains plug when cleaning or servicing the unit, when exchanging any parts or
when changing machine settings for a different function !
•The filter cartridges cannot be regenerated for repeated use !
•The filter cartridges must be disposed of according to pertinent legislation and direc-
tives !
•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 TEKA Service De-
partment: Phone: ++49 (0) 2863 / 92 82 0
•When extracting carcinogenic welding fumes as from the processing of nickel or chrome al-
loys, 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 TEKA-
STRONGMASTER-BGIA2110/4110 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.

4.2 Function description
The Airfilter is used for extracting gases and fumes contaminated with harmful substances.
Either using a suction arm (accessory) extracted directly from the environment of the Airfilter
or a suction hose is directly closed between the machine to be extracted and the Airfilter.
The Airfilter is either switched on or controlled on the membrane keyboard or by the control of
the machine to be extracted (remote switch automatic mechanism).
The gases/fumes extracted by the suction hose/suction arm are extracted into the filter hous-
ing with the used combifilter.
The combifilter consists of the following three filter levels:
– Pre-filter mat,
– Air filter and
– Activated carbon filter with filter end stage.
The clean gas is extracted by turbine below the activated charcoal filter and then emitted to
the atmosphere through the sound absorption module attached at the side.
The Airfilter is connected to the mains supply using a appliance inlet (included). The appli-
ance inlet for the power supply of the Airfilter is positioned on the turbine housing near the
sound absorption module.
4.3 Connection to the external control
A control cable with a sub D9 connection is required for operating the Airfilter via a remote
switch automatic mechanism. The pin terminal assignment of the sub-D9 connection (see in
section 4.5.2) is to be complied with!
