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). RAKM/ RAKM/ Caution: 1. Volume ow has been measured at the clean lters 2. Filtering e ciency 95,6% 3. Our complete o er of the ERGO extractions arms is presented on separate catalogue cards RAKXM/
