Application
              TELERGO extraction arms are designed for eff ective extraction                of welding dust and gas contamination, as well as other small
                dust particles – directly at the emission source, not allowing the
                contamination to spread in the working area and preventing from
                being inhaled by people.
                
              The extraction arms can be applied in any areas where the workspace
                is limited. Commonly, this is the case in welding schools, where the
                welding boots are very small.
              
              The extraction arm can work as a single appliance, with its own
                extraction fan, or in a group of local exhausts
              
              Structure
              Th e extraction arm consists of following assemblies:
  - swivel,
 
- suction hood with a shut-off damper,
 
- pipe segments of telescopic construction – the segments are sliding    one into the another (in case of TELERGO Flex the supporting              
Pipe sheet, of cast aluminium elements. Th e nominal diameter of the arms is 6’’.                The extraction arm is equipped with a frictional joint located near
  the swivel.
Operational use
To install the extraction arm on a wall (or supporting column)  use a wall bracket. Additionally, the wall bracket is an appropriate
  installing point for the extraction fan or the connection fi tting piece.
  
The pipe-segments can be slid telescopically, one segment can turn
  within the other segment, providing the most useful position of the
  suction hood.
  
Adequately adjusted frictional joint gives easy manoeuvrability with
  the arm. The suction hood is equipped with a shut-off damper to
  adjust the air volume fl ow.
  
The TELERGO-L-3-3000 is additionally equipped with a support  of the gas spring improving the manoeuvrability performance.
