ATEX certified gearboxes for zones 1-2-21 and 22, Cat. 2 and 3, Dust and Gas
ATEX is the conventional name of the Directive 14/34/EC for the equipment intended for use in potentially explosive atmospheres.
It imposes the evaluation of the risk for all the equipment operating in such environments.
It classifies several levels of "danger" (zones): to every zone it corresponds a different typology of explosive atmosphere, according to its composition and to its probability and time of appearance.
Motive gearboxes series (BOX-EX, ROBUS-EX, ENDURO-EX, STON-EX e STADIO-EX) are certified according to the norms EN 13463-1, EN 13463-5, EN 1127-1 for the zones 1, 21, 2 and 22

| 2 | 1 | A place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally | yes | ||
| 3 | 2 | A place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only | yes | ||
