TECHNICAL DATA
Filtering devices in welding processes
Application
RAK-type appliance has been developed for cleaning the air
from welding dust arising at mobile or stationary workplaces.
The contaminated air is sucked in at the workplace into the
ltering unit via ERGO extraction arms.
After cleaning the air is returned to the process room.
Filters – after reaching the limit pollution rate, have to be
replaced for new (regeneration is not possible).
RAK is manufactured in mobile and wall-mounting versions.
Structure
RAK consists of subsequent elements:
- radial fan
- net lter (spark catcher)
- ltering pad – class G-
- compact lter – class F-
- active carbon impregnated spunbond lter
- control unit
- castor assembly for the mobile version, or a set of brackets
for the wall mounting version.
The device is manufactured in three sizes, adapted for
installing of one, two or three ERGO extraction arms of a
diameter mm and workrange or metres (ERGO-L/Z-R.
Operational Use
The appliance is operated and controlled by means of
a control unit. In case of the mobile version, the control
unit is built-in on the housing, whereas for the stationary
version, the control unit has to be installed apart from the
device in a place chosen by User. Pressure control in the
device signalises by the lamp the necessity of compact lter
replacement.
Periodical maintenance consists in:
- periodical cleaning the net lter
- periodical replacement of the ltering pad and the carbon
fabric (every several months)
- periodical replacement of the compact lter (according to
the indication of the signalling lamp).
