Explosion-proof counter-rotating axial flow local ventilation fans for mines

Mining explosion-proof extraction type counter-rotating axial flow local ventilation fan (hereinafter referred to as ventilation fan) is a new type of local ventilation fan with a wide range of applications. It has the characteristics of compact structure, low noise, high wind pressure, high efficiency, stable operation in small flow areas and wide range of efficient applications. It is mainly used in underground coal mines with explosive gas environment for extracting local ventilation, and can adapt to different ventilation requirements of the length of the digging face and the tunnel, and is the ideal exhaust equipment for extracting gas, explosive gas, harmful gas and dust from the digging face of the mine. It can also be used in combination with dust extraction equipment to extract dust from the working face. It is also suitable for the ventilation of coal silos, warehouses and large buildings.
