Alsident® System 75 - for air volumes between 80 - 180 m3/h and in diameter Ø75.
System 75 PP (chemical resistant
) is applicable in aggressive working environments. Joints and pipes are made of polypropylene (PP) which is resistant to various aggressive chemicals.
ESD and EX approvals
75 Antistatic is approved for use in ESD areas both by the Danish DELTA and the German BAM according to IEC 61340-5-1 and IEC 61340-4-1.
The antistatic system is also approved for use in EX areas (ATEX areas) according to standards EN 13463-1:2001, paragraph. 18.104.22.168 and IEC 61340-4-1:2003 and are marked accordingly: EX II 1 GD
Therefore, System 75 Antistatic arms have an earthing wire for EX areas attached. For use in ESD areas, an earthing wire with 1MW
resistance is also enclosed separately. You will find further information in the test reports
and in the mounting instructions.
In ATEX areas we recommend brackets made of acid proof stainless steel, which is considered spark free and therefore in compliance with EN 1127-1 5.3 'Mechanically generated sparks'.
Please note that the end user is liable for making the risk assessment of the entire installation.
Alsident System A/S also recommends the earthing of the extraction arm to be carried out by personnel experienced in EX areas.
