Mine fan with electric drive VVM-7 NEW!

The fan is intended for ventilation of blind workings in ore mines with section of 16-35 m2, at air density of up to 1.3 kg/m3, temperature from 268 to 308 K, dust content of air of up to 50 mg/m3, and relevant humidity of up to 95% (at 298 К).

Fans are installed vertically with a permissible deviation of axles from horizontal by not more than 30 degrees. The main feature of the fan is the increased total rated pressure, compared to the serial production units, due to construction advances.

Advantages:

  • 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
  • if required, the fan can be equipped with a muffler
