Operation Principle Of The Extraction Systems Of The Ln, Gl, Bf, Rf, Df, Cr, Tfs Series; Filter Types Used - TBH DF Serie Manual De Uso Y Mantenimiento Original


Monitoring of the extraction capacity in a closed compartment with controlled air supply,
for example via a vacuum sensor, which is evaluated by the process control system
and stops the process in the event of an error.

When using piping which can only be separated from the system with tools, it is
alternatively sufficient to determine the proper function of the filter and extraction
system via the signals of the INSPIRE interface, as far as the pipeline is subject to
regular inspection (weekly). Please also observe the notes in section: "INSPIRE
interface".
Signalling

Use of the TBH signal module for visual and acoustic signalling of the system status.
Please also observe the notes in section: "Signalling of the Extraction and Filter
System" & "TBH Signal Module".

Evaluation of the filter and extraction system status via the process control system. In
this case, the signalling of errors is taken over by the primary control system and must
comply with the requirements of ISO 15012 & EN 60335-2-69 AA.
2.2 Operation Principle of the Extraction Systems of the LN, GL,
BF, RF, DF, CR, TFS Series
Area of Application
Sticky and moist dusts, e.g. laser emissions, soldering fumes, solvent and adhesive vapours
Functional Principle
The air containing pollutants is drawn in/extracted via the extraction device (hood, hose) and
fed into the filter unit by means of a pipe, flexible hose or an extraction arm. Here, the
pollutant particles are filtered out according to their filter class in the various filter stages The
cleaned air is then either returned to the work area or to the outside via a pipe, depending on
the application.

Filter Types Used

Depending on the model (see technical data), the extraction and filter system is equipped
with different exchangeable pre-filters in different filter classes. The filters used are, for
example:
Saturation or Storage Filters
The storage capacity of regular filter media results from the amount of particles (or in the
case of molecular filters, gases) they can absorb. As soon as all free spaces of the filter are
filled with foreign substances, the further use (exception: molecular filter) will lead to an
increase in pressure. This increase in pressure leads to a reduction in the air volume flow
and a filter change becomes necessary.
