The fans are allowed to be used as main ventilation fans. The fan is installed vertically with a permissible deviation of axle from horizontal by not more than 30 degrees. The fan is suitable for air pipes with diameter 1000-2000 mm.
Advantages:
- fans provide stable long-term 24-hour ventilation
- hi-tech aerodynamic scheme with high pressure characteristic
- thermal shutdown in case temperature exceeds normal value or the bearings start to vibrate
- blades of the fan are made of non-inflammable material
- economic
