They are suitable for installation in zone 1/1, that are areas where it is necessary to guarantee high security against explosions and fires due to the presence of flammable gas (II2G) and/or dusts (II2D/II2GD). These fans are certified by IMQ according to ATEX Directive 94/9/CE and to EN 14986 (Certificate IMQ 10 ATEX 017 X).

They are suitable for all the industrial applications where small air volumes and high pressures are required. The series consists of different models with impeller diameter from 200 to 450 mm. The motor is directly fitted to the forward curved impeller. The casing is easily adjustable, also on site, to the required discharge angle every 45°, excluding orientations 180° and 225°which require a special construction.
