The fan is intended for ventilation of blind workings in coal and ore mines 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). The fan is explosion proof, explosion protection level is PB ExdI (PB 3B).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
- economicif required, the fan can be equipped with a muffler
