SI-BACK 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 with relatively low pressures. For instance battery rooms, petro-chemical platform, laboratories etc.
This line consists of 3 series:
SI-BACK A: 15 sizes with impeller diameter from 250 to 1250mm.
SI-BACK B: 15 sizes with impeller diameter from 220 to 1250mm.
SI-BACK C: 9 sizes with impeller diameter from 350 to 800mm.
SI-BACK 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, 2D or 3G, 3D.
