Description

The axial fans of the QC-ATX series are manufactured and certified according to the Atex Directive 94/9/CE and 2014/34/EU.

They are suitable to convey clean air in the temperature range: -20°C/40°C. This version is suitable for installation in zone 1/21, areas in which it is necessary to guarantee high security against explosions and fire that could be caused by the presence of flammable gas (II2G) and/or dusts (II2D/II2G/D). They are certified by IMQ (Italian Institute for Quality) according to EN14986 (IMQ Certificate IMQ 10 ATEX 002 X).
The optimized inlet cone reduces noise level and increases efficiency.
