CVAT/4-4000/400 ND 0.37Kw (230/400V50HZ) EXDIIBHT4 - ATEX RATED CABINET FAN

Range of direct drive backward curved centrifugal cabinet fans designed for ventilation of commercial kitchens and industrial applications.
Cabinet fan manufactured from aluminium profiles and double thickness side panels internally lined with 25 mm thickness of fireproof fiberglass acoustic insulation. Circular duct connection flange on the inlet and outlet. CVAB-N/CVAT-N incorporates direct drive backward curved centrifugal impeller,manufactured from aluminium (CVAB-N) or steel (CVAT-N) sheet, with motor fitted inside the air stream.

Motors:
CVAB-N Single-phase external rotor motors 230V 50Hz, IP55, class F, with thermal protection, speed controllable by tension.
Working temperature from -40ºC to 60ºC.

CVAT-N
Three-phase 4 and 6 pole motors 230/400V 50Hz, IP55, class F, with thermal protection (PTC), speed controllable by inverter.
Working temperature from -20ºC to 40ºC.

ATEX versions:
On request, explosion proof versions in accordance to ATEX Directive, for three phase models.
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.
