Alsident® System 75 - for air volumes between 80 - 180 m3/h and in diameter 75.

System 75 Aluminium is particularly applicable in trades such as laboratories, laser technique, hospitals, chemical industries, pharmaceutical industries as well as food industries, schools, high schools, universities and machine shops. In addition, System 75 is also applicable in hairdressing salons, veterinary hospitals and the electronics industry.
 
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.
 
System 75 Antistatic is approved for use in ESD-areas and explosive EX-areas (ATEX).

ESD and EX approvals

Alsident® System 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. 13.3.4.7 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.

Alsident System A/S is the only manufacturer who have their extraction arms tested thoroughly by acknowledged impartial test institutes. We have our extraction arms tested by Danish Technological Institute, Delta and German BAM.
