Tunnel jet fans are mainly used to extract fresh air from the outside. Tunnels have some ventilation requirements. What do tunnel jet fans need?
查看详情Tunnel fans inevitably generate noise during operation, including aerodynamic noise and mechanical noise. Among them, aerodynamic noise is the main noise, and its sound pressure level is usually more than 10 decibels higher than mechanical noise. It propagates into the surrounding air through the in
