CVAT/4-250 IP55 soundproof radial ducted fan

Cabinet

is of frame construction with 25 mm thick sandwich side panels, which are attached to the cabinet frame with self-tapping screws. The sandwich panels consist of external and internal galvanised sheet metal, with a sound-insulating mineral wool filling inside. The individual panels can be removed. The fan is mounted in the enclosure on sprung profiles to reduce vibration transmission. There are circular necks on the cabinet with single-edge seals. There is a steel mounting frame under the cabinet. The individual panels are interchangeable with the discharge panel. The cabinet is pressurized when the fan is operating.

Speed control

by voltage change (CVAB) or frequency converters (CVAT).

Clamp-on power supply

is located on the casing, on CVAT 710 and 800 on the motor.

Mounting

is carried out only in the position shown on the dimensional sketch with the motor axis horizontal. The location of the discharge throat can be changed during installation by interchanging the throat panel with either side or top full panel.
