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.

- 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.II 2G Exd IIB T4

Note electrical data may vary for ATEX motors.
-
Backward curved centrifugal impellers
To prevent accumulation of dirtiness. Dynamically balanced. -
Low noise level
On request, double thickness side panels lined with 25 thickness of fireproof fiberglass acoustic insulation. -
Robustness
Quality finished aluminium profiles and plastic corners providing a great robustness. -
IP55 external terminal box
To facilitate electric connection. -
