Designed for the main ventilation of mines, mines during the penetration of trunks and general industrial ventilation. Blades of the fan impeller are made of composite materials.

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.
