9.1 General Information
Directive relates not only to electrical equipment, but also to all kind of machines and control components, separately or
jointly, for use in potentially explosive atmospheres.
The following recommendations, issued to operations in potentially explosive environment, are meant as specific comple-
tion to the preceding «Working Instructions».
VARVEL-ATEX gearboxes are manufactured with housings and covers of metallic material, incorporating the transmis-
sion elements fitted on ball and roller bearings, with Viton oil seals on input and output shafts et with the adequate oil
quantity to assure the design operation.
9.2 Prevalent Use
VARVEL-ATEX gearboxes are identified as « components », fundamental but without any autonomous function to oper-
ate units and protection systems for production, transport, storage, measurement, control and conversion of energy, or
the processing of materials which are capable of causing an explosion through their own potential source of ignition.
