They are also suitable as OEM in a wide variety of applications. With the addition of a suitable wall mounting square frame adaptor, the AC fans (from size 800 to 1250) can be converted in a wall mounted fan (like QC range).
The series includes 2 versions: AC/A and AC/B, with impeller diameter from 300 a 1250 mm and different motor polarity. The AC-A model has a shaped cone in the inlet side, while for the AC/B the shaped cone is present also on the outlet. They are designed for clean air in the temperature range -10°C 50°C.
The optimized inlet cone reduces noise level and increases the efficiency.
