FBCD series mining explosion-proof exhausting counter-rotating local fans (hereinafter referred to as fan) is a new generation of novel energy-saving local fan having wide applications. By drawing upon structure and technical performance of existing counter-rotating axial local fans, it is searched and produced to satisfy the demands of some present coal mines for exhausting gas (with gas density not exceeding 3%) and waste air. It is mainly used in underground coal mines with methane explosion risks for medium/long-distance ventilation of coal mining faces.

The product has reasonable structure, complete specifications, high efficiency, remarkable energy conservation effect, low noise and long blowing distance. Moving will be avoided if the tunnels are less than 2000 meters length and then help to reduce the labor intensity, save ventilation time. It is really ideal equipment for local ventilation in underground coal mines. Its structural features: flameproof, counter-rotating, exhausting, axial flow.
