Product Specification FBD series explosion proof ventilation fan (hereinafter referred to as fan) has the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy saving effect, low noise, long air supply distance, etc. According to different requirements of ventilation resistance, the whole machine can be used or used in different levels, so as to reduce the ventilation time and save energy. The length of the tunnel is less than 2000m, so it can not move the ventilator to supply air normally, which reduces the labor intensity of the workers and saves the ventilation time. It is an ideal equipment for local ventilation in the coal mine.

At the same time, it can also be used in metallurgy, nonferrous metals, gold, chemical industry, shipbuilding, ceramics and other high-pressure ventilation occasions. The structure of the ventilator is characterized by explosion proof ventilation fan, contra rotating, silencing and axial flow. It is mainly used in the coal mine with the risk of methane gas explosion, and can be used for the medium and long-distance ventilation of the coal mining face. At the same time, it is also suitable for local ventilation and tunnel ventilation in other mines. Main purpose and scope of application The normal working conditions of the fan are: 1) It is mainly used in the coal mine with the risk of methane gas explosion. It is installed in the air inlet tunnel and used together with the positive pressure air duct for the forced ventilation; 2) Medium temperature - 20 ℃ ~ + 40 ℃; 3) The altitude is less than 1000m; 4) The humidity is not more than 95% (at 25 ℃).
