Technical Data
Unobox fans up to size 450mm have backward curved centrifugal impellers made of plastic with galvanised steel support plates. Fans from 500mm have backward curved high-performance impellers made of aluminium. The impellers are mounted directly on the rotors of the external rotor motors and are dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11. UNOBOX units are suitable for outdoor installation with appropriate accessories.
