The main differences between tunnel fans and ordinary fans are as follows:
1. Different uses: Tunnel fans are usually used for ventilation and exhaust emissions in tunnels, while ordinary fans are used for general ventilation, cooling, dehumidification, etc.
2. Different designs: Tunnel fans generally use impeller inverters for speed regulation, corrosion-resistant materials for production, fire protection design, explosion-proof design, and other special designs to ensure their safe operation in the tunnel; Ordinary fans do not require these special designs.
3. Different sizes: The power and volume of tunnel fans are generally larger than ordinary fans, because the ventilation capacity of tunnels is much larger than that of ordinary places.
4. Different noise levels: Tunnel fans usually require low noise levels as the noise becomes more pronounced inside the tunnel; The noise of ordinary fans is relatively high.
5. Different levels of maintenance difficulty: Tunnel fans are installed in relatively narrow spaces, making maintenance difficult, but it is necessary to ensure their normal operation; Regular fans are relatively easier to maintain.
