The AC-Box series includes boxed fans consisting of centrifugal impellers with backward curved blades directly coupled to standard alternating current (AC) asynchronous motors inserted in a soundproofing plenum (Box) lined with soundproofing material. These fans are particularly suitable for extracting or introducing air in commercial-tertiary and also industrial environments where good silence and high operating efficiency are required, such as offices, gyms, shops, restaurants, engine rooms, cabins and switchboards.

The AC-Box series is made up of 8 sizes with impeller diameters from 350 to 710 mm and with air flow rates up to 16,000 m³/h, maximum pressures available up to 1000 Pa. The AC-Box box fans are characterized by a in aluminum sections, Cl.1 sound-absorbing internal lining, panels that can be easily disassembled to allow inspection and maintenance and to direct the air flow by simply moving them between them, carefully designed backward-curved impellers, versatility of use (possibility of direct the delivery flow either in the same axis with respect to the intake or perpendicular to it).
