Local ventilation fan type VME-4 axial single-stage with explosion-proof removable electric motor with explosion protection level PB ExdI (РВ 3В)

During operation, the fan is installed in a horizontal position with a permissible deviation of the fan axis from the horizontal of not more than 30 °.

Fans are used in ventilation systems of mine workings, they are mainly intended for ventilation of blind workings, as well as mine shafts and round-bore workings during their sinking. Fans are explosion-proof, can be used in coal mines hazardous in gas and dust, because exclude explosive situations.

The VVM-8 counter-rotating shaft mine fan with an explosion-proof electric drive is designed to ventilate dead-end mines with a cross section of 16 to 35 m2 at an air density of 1.3 kg / m3, a temperature of 268 to 308 K, dust content of up to 50 mg / m3 and relative humidity up to 95% (at a temperature of 298 K).

The VME-5 local ventilation fans are designed for ventilation of blind workings with air density up to 1.3 kg / m3, temperature from 268 to 308 K, dust content up to 50 mg / m3 and relative humidity up to 95% (at a temperature of 298 K). Explosion-proof fans with explosion protection level PB ExdI (РВ-3В). Aerodynamic characteristics allow the fan to be used in relatively small deadlock workings.
