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. Standard configuration with inline airflow but with outlet configurable as required.
Motors
CVAB
Single-phase external rotor motor 230V±10%, 50/60Hz,
IP55, Class F, thermal protector and
speed controllable by tension. Operating temperature
-40ºC to 60ºC.
CVAT
Three-phase motors 230/400V±10% 50/60Hz, IP55,
Class F and speed controllable by frequency.
Thermal protector (TP) type as default from factory with the exception of 710 and 800 which use PTC type. On demand, PTC thermal protection type for smaller models.
Operating temperature -40ºC to 60ºC.

Note: CVAT/4-710 model, only 400V±10% 50Hz
On request, explosion proof versions in accordance to ATEX Directive, for three phase models.
Working temperature from -20ºC to +40ºC.
Note electrical data may vary for ATEX motors.
Working temperature from -20ºC to +40ºC.
- ATEX Flameproof - Gas:
In standard ATEX version flameproof motors are without thermal protection.
If used with frequency inverter,flameproof motors with a PTC-type thermal protection must be specified at order.
