Sickle formed axial impellers result in a very low noise spectrum. The main concern was to keep noise emission low in the main range of application of the fan, while having an optimal performance curve with the long and short inlet cones. The impellers are designed as follows:
n

size from 350 to 450

size from 450N to 630
n
of aluminium sheet
