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.
The company was founded in 1993 and, after decades of development, has been able to produce over 200 series and over 1200 products, with an annual production capacity of 20 million. The products are widely used in industries such as boilers, workshops, mines, textiles, oil fields, chemicals, kilns, metallurgy, power plants, cement plants, alumina, electrolytic aluminum, building materials, etc. The mining fans, axial flow fans, cotton opening fans, and material conveying fans produced have been inspected by customs and commodity inspection departments and exported to Southeast Asia, Pakistan, Algeria, Kazakhstan, and other countries, deeply favored in the international market.
