Atex fire dampers represent passive fire protection, designed with the help of compartmentalization to prevent the spread of toxic gases, smoke and fire. Standard fire dampers are designed and certified in accordance with EN 15650 and tested for EIS criteria according to EN 1366\u20132. Fire dampers together with their installation form an inseparable part of a fire resistivity rating.<\/p>\n

This Atex version is modified by the 2014\/34\/EU directive, which sets out the technical requirements for equipment and protective systems intended for use in potentially explosive atmospheres.<\/p>\n
