VME-4

Application of VME-4 Fan

The local ventilation fan type VME-4 is an axial single-stage fan equipped with an explosion-proof removable electric motor with an explosion protection level of PB ExdI (PB 3V).

It is designed for ventilating dead-end mine workings in coal and ore mines, including those hazardous due to gas and dust, with air density up to 1.3 kg/m³, temperatures from 268 to 308 K, dust concentration up to 50 mg/m³, and relative humidity up to 95% (at a temperature of 298 K).

During operation, the fan is installed in a horizontal position with an allowable deviation of the fan axis from the horizontal not exceeding ±30°.

Upon customer request, the fans can be supplied for voltages of 380 V or 660 V.

Advantages of the local ventilation fan VME-4

• possibility to shut down the fan when the normal temperature is exceeded
• energy efficiency
• suitable for ventilating small workings
• on request, the fan can be equipped with a noise silencer
• dynamic balancing of the impeller to a high accuracy class ensures long-term and reliable operation
• the fan design includes a surge protection device, which expands the operating range and prevents surging
