Tunnel fan price

Tunnel fan priceMainly used for ventilation and air exchange in underground railways, it can also be used for ventilation and air exchange in railway tunnels, caves, underground engineering and buildings. It is a high-pressure, low-noise, high-efficiency axial flow fan.

Tunnel fan priceIn response to the current situation where there is no such series of fans in China and the booming development of underground engineering buildings requires a large number of imports, the CAD system software used has been optimized through multi-objective design to match the blade shape and machine number of general underground engineering buildings and subway tunnels in China. Its technical performance indicators have reached or partially exceeded similar foreign products.

Tunnel jet fans include unidirectional jet fans and bidirectional jet fans. There are electronic and mechanical types of bidirectional jet fans. It can switch to the rated speed of the fan in both forward and reverse directions within 30 seconds. For occasions with high noise requirements, mufflers can be added to reduce their noise. Product features: The shell is formed by spinning and flanging imported from the United States, and the inner wall of the impeller section is precision machined, which is corrosion-resistant, reliable, and economical. A muffler can also be added to reduce its noise. Direct drive, low maintenance workload

development:
The new high-efficiency and energy-saving tunnel fan FD can be equipped with noise reduction devices at both ends, and its noise can be controlled within 80 decibels
The FD tunnel's cyclone fan press in fan is a new generation of widely used energy-saving local ventilation fan developed and produced based on the summary of the existing domestic counter rotating axial flow fan structure and technical performance.
The FD tunnel has the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy-saving effect, low noise, and long air supply distance for the cyclone press in fan.
According to different ventilation resistance requirements, the FD tunnel can use the cyclone press in fan as a whole or in stages, thereby reducing ventilation power consumption and saving energy. The length of the tunnel is within 2000m, and the fan can supply air normally without moving, reducing the labor intensity of workers and saving ventilation time. It is an ideal equipment for tunnel ventilation.
The FD tunnel can be used for high-pressure ventilation in industries such as metallurgy, non-ferrous metals, gold, chemical, shipbuilding, and ceramics.
The structural characteristics of the FD tunnel's cyclone press in fan are counter rotation, noise reduction, and axial flow.
