Ring Atex line is designed to grant a correct air extraction avoiding risks of explosion due to the presence of flammable gases. For instance in ventilation of battery rooms, petro-chemical platforms, laboratories etc., for wall or panel fixing.

This line consists of 13 sizes with impeller diameter from 300 up to 1250 mm.

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