The antistatic extraction arm in System 75 and System 100 are very different from the arms of other materials, because both tubes and joints are made of shatterproof conductive polypropylene (PP).
System 75 AS and System 100 AS have both been tested and approved for use in Ex areas (ATEX) according to EN 80079-36-2016 and EN 80079-37-2016 and are therefore labelled: Ex II 1 GD
Therefore, these extraction arms are delivered with an earthing wire. Since they have also been tested and approved for use in ESD areas according to IEC 61430-5-1:2016, we also enclose an earthing wire with 1MW resistance.
The stub pipe for the antistatic extraction arm is made of conductive polypropylene (PP) and is delivered together with the hood. The hoods are made of TCP treated aluminium or vacuum-moulded conductive polypropylene (PP).
