The use of products in potentially explosive areas places special requirements on their safety. The European Union has laid down these requirements in the ATEX Product Directive. All Hürner-Funken fan models are optionally available with ATEX-compliant explosion protection. Hazardous areas are classified into zones based on the frequency of the occurrence and duration of a potentially explosive atmosphere. Products are available for use in Zone 2 and Zone 1.
The standard temperature class is T3, while T4 is also optionally available. Registration with the National Metrology Institute of Germany (PTB) guarantees compliance with the applicable standards.
