These fans are certified by IMQ according to ATEX Directive 2014/34/EU and to EN 14986 (Certificate IMQ ATEX 019 X). They are suitable for installation in zone 1/21, that are areas where it is necessary to guarantee high security against explosions and fires due to the presence of flammable gas (II2G) or dusts (II2D/II2G). The tube axial fans of CC series are used for ducted installations requiring large airflow with relatively low pressure drop, like ventilation and cooling systems in industrial, naval, commercial, civil, energetic fields. This
series has, compared to centrifugal fans, the advantage of being smaller in dimensions and easier to be installed. The series consists of different sizes with impeller diameter from 310 to 1600 mm.
