FUME EXTRACTION ARMS
The extraction arm consists of following parts:
• 2 pipe-segments integrated by frictional joints, damper
• gas springs to balance the weight of the segments
To install the arm on the wall or supporting column – use the wall bracket type WB. The arms can also be fixed at the end of the rotational arm – type RO. Both the extraction arm as well as the rotational arm are adapted for attachment directly on a wall bracket (where the flange fastened fan type WP-E is fixed).
Accurately adjusted frictional joints working with the springs – assure a convenient arm manoeuvring and it is easy to change the arm position. The hood can be equipped with a halogen spot-light (to light up the work field) and a photo-resistor that is (through the ZE-ERGO control unit) starting the fan automatically at the moment of the welding-arc flash.
For the arms working in application with a hood without the halogen light and the photo-resistor – use motor switches, (chosen from the catalogue FANS – electrical accessories: WS, RS, ?S).
Recommended flow capacities for following arm sizes: 1200 cfm for Dn = 8″, 600 cfm for Dn = 6″, 400 cfm for Dn = 5″, 200 cfm for Dn = 4″.
