Operation
The WallPro works in accordance with the recirculation
principle. Welding fume is extracted through the hood of the
connected extraction arm(s) by the fan. The polluted air
passes the deflector plate(s)
5
behind the inlet opening(s) and
is cleaned by the filter cartridge. The welding fume particles
are collected at the outside of the filter cartridge. The cleaned
air is returned in the workshop through the outlet of the fan or
exhausted to the atmosphere via an outlet duct.
2.2.1 Filter cleaning system
The WallPro is provided with the RamAir™ pulse amplifier,
which thoroughly cleans the filter cartridge by compressed air
pulses from the inside out. Filter cleaning mainly takes place
offline (=while the fan is off)
6
. If the pressure drop over the
filter cartridge reaches the pre-set threshold value during use,
an online cleaning cycle takes place. You can activate the filter
cleaning system manually as well (both offline and online).
The dust and dirt particles fall into the dustbin.
Refer to paragraph 5.3 for more details about the
activation of the cleaning system.
5. To protect the filter cartridge and to distribute the air equally inside the unit
6. Offline filter cleaning is the most effective way of cleaning. The combination of
offline and online cleaning guarantee the optimum performance of the unit.
