Fan Overview
The series flameproof counter-rotating axial flow local ventilator is a new type of local ventilator with a wide range of uses. The machine has the characteristics of compact structure, low noise, high wind pressure, high efficiency and reverse wind. It has the characteristics of good performance, stable operation in small flow areas, high efficiency and wide application range. According to the length of the excavation working face and the different ventilation requirements of the tunnel, it can be used as a complete machine or in stages, thereby reducing energy consumption and saving energy. It is an ideal equipment for local ventilation in mines. This series of fans is mainly used for local ventilation in coal mines with the risk of gas or coal dust explosion. It is also suitable for metal mines, chemical mines, tunnels and other factories and mines where fans are used. The temperature of the conveying medium does not exceed ℃, the humidity does not exceed 3 (℃) and it is non-corrosive.
