The ventilation mode of tunnel jet fans is usually determined based on factors such as tunnel length, cross-sectional dimensions, and construction methods. Tunnel jet fans are mainly used to extract fresh air from the outside. Tunnels have some ventilation requirements. What do tunnel jet fans need?

The tunnel jet fan must maintain normal operation. If you want to stop running, other operations affected by the pause must be stopped.

It is prohibited to place impurities below 5 meters of the tunnel jet fan. The outlet of the fan must be filtered and safety measures must be taken. If there are any problems, it can be paused.

Tunnel jet fans should have sufficient spare parts. What are the ventilation requirements for tunnel jet fans?

If the wind speed in the tunnel is lower than the required specifications, the wind speed can be increased by increasing the pressure of the tunnel jet fan.

The main fan equipment must meet the requirements of the ventilation plan, and the auxiliary fans in the tunnel must adopt a new air flow rate; The main fan must be built on a hole of at least 30 meters and have certain depressions.
