Through direct drive the fan speed can be varied
in the following steps:
750 - 1000 - 1500 - 3000 rpm at 50 Hz
900 - 1200 - 1800 - 3600 rpm at 60 Hz
Through belt drive a wider range of speed can be obtained.
These variations give a wide working area for the axial fan
M 80. lt is possible to obtain capacities from 360000 m³/h
using fan 2000.630.8A/M 80 down to 1800 m³/h with the fan
400.250.6A/M 80.
lt is further possible to obtain pressure up to 3600 Pa with
the fan 800.500.8C/M 80. |
