1 ACOUSTIC CABINET FANS CENTRIBOX CVB / CVT Series Cabinet fans manufactured from heavy gauge galvanised steel sheet and internally lined with melamine foam flame retardant acoustic insulation (M1). All models incorporate double inlet single phase direct-drive forward curved centrifugal fan fitted with anti vibration mounts and IP55 remote terminal box. All cabinets can be installed outdoors as standard. Available, depending upon the model, with single phase motors in 4 or 6 poles. Motors Motors are IP44 (1) Class F insulation, with ball bearings and thermal protection. Electrical supply: Single phase 230V-50Hz. Three phase 230/400V-50Hz. (See characteristics chart). All models are speed controllable. (1) Model CVT 380/380-N-2200W is IP54 Class F. Outdoor installation Easy to mount Acoustic insulation of 7 mm All cabinets can be installed All models are supplied with thickness flame retardant (M1) outdoors as standard four mounting feet to facilitate installation melamine foam reducing the noise level significantly Flame retardant IP55 remote terminal box Anti-vibration mounts Circular duct connection flanges To ease installation and Reducing vibration and noise In line circular duct connection connection to external controls transmission to the installation flanges at the inlet and discharge P L I C A T I O N Warehouses Workshops Commercial premises Offices Restaurants and cafes Commercial and industrial kitchens S Low noise level P A

2 Technical characteristics Before installation check that the product electrical characteristics listed on the data plate label (Voltage, power, frequency etc) match those of the intended electrical supply. * The sound levels shown on the curves are radiated sound pressure levels, measured at 1,5 m, in free field conditions and outlet ducted. Acoustic characteristics Speed Motor power Protection absorbed Insulation class Sound power level spectrum in db(a) at the corresponding frequency band in Hz: The sound levels NPS- shown in the technical characteristics chart for the S&P fans, generally correspond to a value of sound pressure db(a), measured in free field conditions at a distance of 1,5m.
