Properties
- flow rates up to 36,000 m³/h
- size: 315 - 1000 mm (impeller diameter)
- asynchronous external rotor motor
- sickle-shaped impellers
- terminal box design; alternatively, lateral or axial cable outlet
- protection class IP54, thermal class F
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:
size from 350 to 450 made of sheet steel
size from 450N to 630 of aluminium sheet
size from 710 to 1000 of profiled cast aluminium impellers
Guard
Serving as contact protection and for mounting the fan onto the inlet cone.
