Helical gear reducer RK A series

coaxial200 - 500 Nmtransmission

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.
