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.
