Tunnel Axial Fan

Tunnel-type axial flow fans are mainly used for ventilation of subways, and can also be used for ventilation of railway tunnels, caves and underground engineering buildings. It is a high-pressure, low-noise, high-efficiency axial flow fan.

Application:
Tunnel construction fans are mainly used to discharge during tunnel construction. Due to the explosion of explosives, the use of internal combustion engines, and the release of harmful gases from the stratum during excavation, it provides a good construction environment for tunnel construction, maintains the health of operators, and ensures normal and smooth construction. , an important condition for improving work efficiency and ensuring project quality.
During tunnel construction, due to drilling, explosive blasting, slag loading, injection of concrete, exhaust from internal combustion engines and transport vehicles, there is too little oxygen in the tunnel. The air in the narrow space is very turbid and polluted, which has a serious impact on human health. It is necessary to supply fresh air to the cave, remove harmful gases, and reduce dust concentration. The effective and general method is to use various fans and air ducts to exhaust and ventilate dust.
