Редукторы серий ARA, ARG, ARKE Fimet

The aluminium RA series and the cast iron RG and RKE series have been appropriately modified in order to make them suitable to run in a safe way in atmospheres potentially exploding because of presence of dust and/or gas , according to the european directive ATEX 94/9/EC. 

As a consequence of this their names have been modified introducing the prefix A.
They can run in environments identified as follows :

•  II 2D , zone 21
•  II 3 D , zone 22 
•  II 3G , zone 2.
  and can be coupled to same level certified and homologated FIMET motors. 
  Since they are gearboxes , that is just mechanical units , they can also run in environments identified as follows :
•  II 2G , zone 1.
  In such case the motor to be coupled must absolutely be choosen in a consistent way , being it out of the FIMET manufacturing range.
