2.2 Operation
The Mobiflex 300-E works in accordance with the recirculation
principle. The welding fume is extracted by the extraction fan
and enters the spark arrester via the extraction fan housing in
the heart of the filter. In the spark arrester the larger particles
and any sparks are separated. It also ensures an even air
distribution.
The next component is the ioniser. The high ionisation voltage
(+10 kV) electrically charges the dust and dirt particles. As soon
as the particles enter the collector, the collector voltage of +5 kV
makes them adhere to the earthed plates. This electrostatic
filter principle has been visualised in Fig. 2.2.
The characteristic feature of this separate combination of ioniser
and collector is the extremely high separation rate, the low air
resistance and the easy serviceability of the separate
components.
The last component is the final filter which mainly ensures an
even distribution of the airflow. Via the outlet grid in the filter
cover the cleaned air is returned in the workshop.
