Operation
2.2.1 MDB-Diluter
The air -that contains welding fume- is extracted through the
air inlet module on top of the unit. The larger particles and any
sparks are separated by a labyrinth-shaped
4
spark arrester.
Subsequently the air is cleaned by the eight filter cartridges.
The air then passes the extraction fan and a duct silencer. The
clean air is blown back into the workshop by the outlet unit
with adjustable nozzles.
The filter cartridges are cleaned individually from the inside
out by compressed air pulses. This filter cleaning system is
called the RamAir™ pulse amplifier. The dust and dirt particles
are collected in the dustbin.
The fan speed is pressure controlled.
Apart from air cleaning, the system optimises the present
natural ventilation (draught) and/or forced ventilation (roof/
wall fans) system and equally distributes the present welding
fume to reduce the background concentration of welding fume
in the workshop.
2.2.2 ControlPro
ControlPro is an intelligent platform that controls the filter
system as well as the connected extraction fan. It contains an
extensive feature package to monitor and arrange the
RamAir™ pulse amplifier (filter cleaning system), the required
airflow and the corresponding fan speed. By means of the
user-friendly HMI you can program all desired parameters. The
HMI gives a clear insight into the system status and
performance at all times.
ControlPro allows for remote access via a network connection.
