The counter-rotating axial flow fan for tunnel construction is a new generation of energy-saving, high-efficiency and low-noise counter-rotating axial flow local fan. The fan has the characteristics of compact structure, low noise, high pressure, large flow, high efficiency, smooth operation and easy maintenance. Features. During tunnel excavation construction, energy consumption can be greatly reduced and energy saved. Counter-rotating local ventilators are used during tunnel construction. Their large flow rate and high wind pressure can reduce the number of ventilators used and increase the ventilation distance. Their compact structure facilitates transportation and installation during construction.
