Axial new generation main ventilation fans VО-25R3

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.

Ability of manufacturing compact block-modular fan systems, providing 100% air flow reversing.
