The AC-BOX series consists of backward-curved centrifugal impellers directly coupled to standard asynchronous AC motors, housed in a soundproofing plenum (BOX) lined with sound-absorbing material. It is particularly suitable for extracting or supplying air in commercial (offices, gyms, shops, restaurants) or industrial environments (machine rooms, electrical panels…) where quiet operation is required.

The series comprises 8 sizes with impeller diameters from 350 to 710mm and airflow rates up to 16,000 m³/h. Maximum available pressures up to 1000 Pa.
