The FBCD series mine explosion-proof exhaust-type counter-rotating axial flow local fan (hereinafter referred to as the fan) features a compact structure, low noise, high wind pressure, large airflow volume, and high efficiency. The aerodynamic performance of the fan meets the requirements for quantitative local ventilation or dust removal in mine tunneling faces. When connected to ducting, it minimizes system losses and operates stably in low-flow regions, with a wide range of high-efficiency applications. Depending on the length of the tunneling face and the ventilation requirements of different roadways, the fan can be used either as a complete unit or in stages, thereby reducing energy consumption and conserving resources. It is an ideal ventilation solution for medium-to-long-distance local ventilation in mine tunneling operations.

The fan is primarily designed for exhaust-type local ventilation in coal mine underground environments with explosive gases such as methane. It can extract and discharge localized methane gas and can also be used in conjunction with dust removal equipment to eliminate dust from working faces. It serves as an ideal device for extracting methane and dust in underground coal mines.
