2.2 Operation
The Wallflex works in accordance with the recirculation
principle. Welding fume is extracted through the hood of the
connected extraction arm (1 or 2) by the fan. The polluted air
passes the deflector plate(s)
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 Wallflex is provided with a 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) . If the pressure drop over the filter
6
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.
