2.1 General description
Filter types
Pre-filters:
The extraction and filter system is equipped with different exchangeable pre-filters in different filter classes depending
on the model (see technical data). The system uses, for example,
•
Aluminium mesh filter (G3)
•
Filter mats (M5)
•
Pocket filter (M5)
•
Z-line filter (M6)
•
Z-linepanel filter (F7)
•
MP-TEC filter (F7)
•
SafeLine filter (F9)
The pre-filter protects the downstream particle filter thereby increasing the service life of the system considerably.
Changing the pre-filter is shown separately (individual filter monitoring) depending on the type of system.
Main filter:
Depending on the type of device, either a particle filter or a cleanable filter cartridge acts as the main filter. The
equipment used are, for example,
•
Filter cartridges (95% , dust class M)
•
Particle filter (99.95% , H13)
•
Particle filter (99.995% , H14)
The main filter ensures that more than 99.95% (particle filter H13), 99.995% (particle filter H14) and 95% (filter
cartridge, dust class M) of the extracted smoke and dust particles remains in the filter (as per DIN EN 1822). This still
holds true when the filter insert is partially or completely saturated. However, as the saturation of the filter increases,
the extraction level of the filter unit decreases.
Activated carbon filter
The service life of the activated carbon filter mainly depends on the specific application conditions and therefore
cannot be predetermined. If there are unpleasant odours, this means that the saturation level of the activated carbon
filter has been reached and the filter must be replaced. The activated carbon filter is not monitored by the filter
saturation indicator.
