VAT Atex Fans
SIA had the spark-proof version of its fans examined by TÜV Italia, which after conducting the necessary checks, issued its certification of the product. For this reason, in addition to the usual Atex certificates, SIA can provide with these fans the statement of conformity issued by TÜV Italia in the capacity of an external certification body.
Fans with Atex certification have been designed and manufactured for use in zones classified as 1/21 and 2/22 and are suitable for conveying flammable and combustible substances, in accordance with the guidelines of the ATEX Directive 2014/34/EU.
