Features of the fan
SDF (C2) type “variable pole multi-speed” fan, one machine is multi-purpose, in the process of use, the blade angle can be adjusted, maintenance and replacement are convenient. According to the ventilation distance of construction, the speed of different power can be used at any time, and the noise is low, energy consumption is low, and the performance is reliable. Especially for long-distance and large-section tunnel construction, the advantages of erenergy saving, high efficiency and low noise can be exerted.
