Axial new generation main ventilation fans VО-25R3

Electric drive power, no more than, kW
Nominal air feed, m3/s
Operating wheel diameter, mm
Rotation frequency, rpm

Main advantages:

  • Working blades are manufactured of high-tensile stamped duralumin.
  • Minimum clearance between the working wheel blades and fan frame provides 88% efficiency.
  • Anti-stall device provides stable operation in every mode of fan working area.
  • Brake prevent spontaneous rotation while electric motor is off.
  • Ejector system decreases bearings temperature and excludes oil spillage from rotor bearing assemblies by creating negative pressure in its spaces.
  • European-made spherical rolling bearings with splined fixation to the shaft.
  • Diffuser with low pressure losing coefficient.
  • Transition from operating fan to reserve one is not more than 8 min.
