MZ Aspiratori has had its fans built in the non-sparking version examined by Tüv Nord Cert GmbH of Hannover, which, having made the necessary checks, has issued a Product Certification. For this reason MZ Aspiratori is able to supply these fans, in addition to the usual Atex certificates, with the Statement of conformity issued by Tüv Nord as an external certification body.
The Atex certified fans have been designed and manufactured for use in areas classified as 1/21 and 2/22 and are suitable for conveying flammable and combustible substances, in accordance with the indications of the ATEX Directive 2014/34/EU.
When the danger is due to the presence of gases, vapours or mists of flammable substances, European Directive 1999/92/EC provides for classification in three zones defined as follows:
ZONE 0 Not possible
ZONE 1 2G fans
ZONE 2 3G or 2G fans
When the danger is due to the presence of combustible dust, the European Directive 1999/92/EC provides for a classification in three zones defined as follows:
ZONE 20 Not possible
ZONE 21 2D fans
ZONE 22 3D or 2D fans
