2 Preface
One sector of extraction equipment has become very significant in recent years. The filtering of
extracted pollutants and the recycling of filtered air to the working area.
This is a surely a sign that the environmental consciousness of each one of us has altered very
strongly in favour of our environment. For a long time now, no-one has denied that pollution occurs
during production. However, the pollutants depend on the process that is used. One can basically
distinguish between gases and smoke. Smoke could also really be described as dust. If you
examine this dust under a microscope, you will find that it consists of very fine particles, often with
a size of 0.001 mm or smaller, that can enter the lungs.
The classical method of trying to improve the working conditions of polluted workplaces is general
ventilation. In this case, the general rule is a multiple change of air in the workshop, i.e. the
complete volume of air in the workshop is replaced. However, this method only achieves a small
reduction in the level of pollution within the breathing space of the user.
The same applies to the so-called “overhead extraction”, i.e. the installation of large extractor
hoods above the workplaces. With this, the worst air flow imaginable, the pollutants first pass
through the breathing space of the user, and only afterwards are they contained and extracted.
This is surely not the point of the exercise. A much more effective method than overhead/wide-area
extraction is the removal of pollutants directly at their source, with localised extraction. Both the
investment and the operating costs are very much lower if localised extraction is used.
The environmental and workplace-safety measures are especially important requirements for
successful application of a technology, in addition to the technological optimisation of the
processing method. In a time of increasing sensitivity and tougher legislation, the task therefore lies
in making an early assessment of the potential hazards for the workplace and the environment, and
reducing them as appropriate.

Function of the TEKA-LMD 508
The TEKA - LMD 508 filter equipment is primarily used for localised extraction of dust, smoke
particles and gases. For this purpose, the unit is equipped with two flexible extractor hoses, or an
extractor fitting that is appropriate to the application.
Limits of application:
welding fumes with oil mist, aluminium dust, grinding dust, extraction of metallic dust, water etc.
(If you are uncertain, please contact the manufacturer!)
The polluted air is gathered in by the extractor fitting and transported to the filter equipment through
the extractor hose. Coarse dust particles are then filtered out in the prefilter matting (Pos.13). The
following particle filter (fine filter, Pos.14) extracts the extremely fine smoke particles with an
efficiency of better than 99%. In a further filter stage, the activated-carbon cassette (Pos.15)
adsorbs the gaseous pollutants. The filtered air is then sucked in by the turbines and returned to
the air in the environment through the exhaust mesh on the sound absorption module.
The LMD 508 filter unit can be connected to an external filter monitoring through the Harting or
Sub-D 9-pin socket (Pos.21) (available as an option).
Warning:
As soon as the airflow resistance of the filter has increased to the point where the suction force
decreases, the filter must be replaced, because it is clogged with the extracted dust and smoke
particles.
(see Section 7.1: “Replacing the prefilter matting”, Section 7.2: “Replacing the particle filter”
and
Section 7.3: “Replacing the activated-carbon cassette”)

Operation of the system
Attention:
Possibilities of adjustment of the programme, menu navigation ecc of the system you will find in the
attached manual of the steering.
7
Maintenance
The filtering out of dust particles means that the prefilter (coarse) and the particle filter (fine)
become increasingly dirty, and the suction power decreases.
The mechanical filter insert ensures that more than 90% of the pollutants that are sucked in are
trapped in the filter. This is still so, even if the filter insert is partially or completely saturated. But
the suction power of the filter unit drops as the saturation level increases.
The saturation level of the filter is electronically monitored. In order to maintain the rated suction
power of the unit, the filters must be replaced when the red flow volume indicator lamp (Pos.5)
lights up.
The prefilter matting (Pos.13) must be replaced at regular intervals.
(see Section 7.1: “Replacing
the prefilter matting”).
Please check at least weekly the pollution of the pre-filter mat
.
As soon as the airflow resistance of the filter has increased to the point where the suction force
decreases, the particle filter (Pos.14) must be replaced, because it is clogged with the extracted
dust and smoke particles.
(see Section 7.2: “Replacing the particle filter”)
The activated-carbon cassette (Pos.15) must be replaced if gas starts to come through to the
clean-air side. At the very latest, the activated-carbon cassette must be replaced when the particle
filter is replaced.
(see Section 7.3: “Replacing the activated-carbon cassette”)
The working lives of the prefilter matting, the particle filter, and the activated-carbon cassette are
strongly dependent on the specific conditions of use. So they cannot be determined in advance.
The filter equipment includes a maintenance-free AC-operated turbine.
Warning:
The operation of the filter unit must be stopped while the filter insert is being replaced.
Filter replacement and disposal must only be carried out in well-ventilated rooms, and a proper
respiratory mask must be worn.
We recommend: a respiratory half-mask to DIN EN 141/143 protective level P3 or equivalent
national standard.
The filters should only be replaced by a member of staff who has been properly trained!
Dispose of the filter inserts in accordance with the legal regulations!
If the filter is manually tapped out, washed, or blown out, then the filter material will be damaged.
The pollutants will spread into the air of the room.
