Sirocco Atex fans are designed to grant a correct air extraction avoiding risks of explosion due to the presence of flammable gases or dusts. They are intended for ducting installations requiring high airflows and relatively low pressures. For instance battery rooms, petro-chemical platforms, laboratories etc. This line consists of 9 sizes with impeller diameter from 180 up to 450 mm.

Sirocco Atex line is characterized by particular materials and design to avoid as much as possible the risk of explosion, according to ATEX 2014/34/UE directive. Different constructions are foreseen for fans in category 2G, 3D or 3G, 3D.
