Product Description
FBD series mine explosion-proof press-fit counter-rotating axial flow local ventilation fans are developed by our company on the basis of summarizing the structure and technical performance of existing domestic mine counter-rotating axial flow local fans, and produce a new generation of widely used fans. New energy-saving local ventilator.
FBD series mine explosion-proof press-fit counter-rotating axial flow local ventilation fans have the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy saving effect, low noise and long air supply distance. According to different ventilation resistance requirements, it can be used as a whole machine or in stages, thereby reducing ventilation power consumption and saving energy. When the length of the tunnel is within 2000m, the fan can be used for normal air supply without moving the fan, which reduces the labor intensity of workers and saves ventilation time. It is an ideal piece of equipment for local ventilation in mines.
FBD series mining explosion-proof press-in counter-rotating axial flow local ventilation fans are mainly used as press-in local ventilation fans in coal mines. They are suitable for local ventilation occasions in mining working faces and various chambers. At the same time, they are also suitable for other mines. Local ventilation occasions and various tunnel ventilation. The ventilator can be placed flat on the floor of the tunnel or hung on the wall of the tunnel. The gas temperature in its environment is -20~40ºC. The dust content of the gas passing through this product shall not exceed 200 mg/m3. It should be installed on In the air inlet flow where the gas concentration in the coal mine is less than 1%, when the gas concentration exceeds 1%, the power supply should be cut off immediately.
