New direct-drive acoustic ventilation units with improvements in airtightness, robustness, ease of assembly and repairability. Ventilation units with low noise levels, made from aluminium profiles and sandwich-type panels, with non-flammable (M0) 25 mm thick glass fibre acoustic insulation, backward-curved centrifugal impeller and dynamically balanced. Installation possible in any mounting position. Standard configuration with inline airflow but with outlet configurable as required.

Available on request, except sizes 710 and 800, explosion-proof versions according to
the ATEX Directive for three-phase models:
For operation at temperatures from -20ºC to
+40ºC.
- Flameproof - Gas
II 2G Exd IIB T4 II 2G Exd IIB+H2 T4 (with Exd IIC T4 motor)
In the standard ATEX version, flameproof motors are supplied without thermal protection.
For use with frequency converters, order flameproof motors with PTC-type thermal protection.
- Increased safety - Gas (cannot be used with frequency converters).II 2G Exe IIC T3
Notes: electrical data may vary for ATEX motors.
- To select CVAT ATEX, use performance curves or Easyvent and allow for a 30% reduction in performance compared to the standard version.
- Electrical data may vary for ATEX motors.
- External dimensions may vary depending on size.
