Filter Material
The extraction systems are fitted with
cartridge filters. The filter material used is
certified for dust class M. The permeability
for dust class "M" as per DIN EN 60335-
2-69 is less than 0.1%. A filter certificate
is available on request. The filter material
used is registered under test certificate
no.: 9101201/6210.
Functional Description and
Adjustment of the Suction Machine
Only dry dust may be extracted. Any
liquids which get it inside the
extraction system can damage the
dust filter cartridge beyond repair!
4.2
Dedusting System
To prevent the pores of the dust filter
cartridge (24) from becoming clogged
there is a dedusting system (25) (rotary
air nozzle) inside the dust filter cartridge.
The filter surface is automatically subjected
to compressed air by the rotating
dedusting system at fixed intervals. The
interval is set to 10 minutes by default
but it can be changed by our Customer

Maximum Mode for Laboratory Cleaning and Pipework Maintenance
You can switch off the automatic control
system by pressing the Maximum button
(8) for maintenance work, which is loca-
ted on the front of your extraction
system and can also be connected to
your laboratory rooms on request. Then
the blower runs up to maximum speed,
and hence maximum suction, for a fixed
period of time (the default is 15 minutes).
If you press the Maximum button again,
the system resumes automatic control
mode. Maximum suction is required
when cleaning laboratory rooms or the
main pipes. For maintenance work
(cleaning the main pipes) read more in
section 7.5 on page 25.
Service on the timer (37). The timer
actuates the valve (36). A compressed-air
cylinder (34) is necessary for the filter
dedusting system. The compressed-air
cylinder is fitted with a pressure-reducing
valve (39), which restricts laboratory
compressed air to 3 bar, and a safety
valve (38) (set to 3.5 bar).
