FBCD withdrawable explosion-proof counter rotating fan

The FBCD extraction explosion-proof counter rotating fan is suitable for use in environments containing explosive substances (gas and coal dust) underground in coal mines. It is used for extraction type local ventilation and can meet the needs of mine ventilation networks and safety production. Extracting local gas accumulation underground or using it in conjunction with dust removal equipment to remove flour dust and change the working environment is an ideal equipment for extraction type local ventilation.FBCD withdrawable explosion-proof counter rotating fanIt is the latest energy-saving local ventilation fan developed and produced to meet the current needs of some coal mines for discharging gas and polluted air (gas concentration not exceeding 3%). This series of ventilation fans has the characteristics of compact structure, low noise, high air pressure, large flow rate, and high efficiency. According to different ventilation requirements, it can be used in both rotary and standalone configurations.
