Tunnels, particularly longer tunnels that cannot always naturally ventilate themselves quickly, need ventilation equipment installed to introduce fresh air and exhaust smoke and dust. Axial fans are best suited for tunnel ventilation and can automatically run in specific concentrations of soot and gases. They can run in reverse in the case of fire to quickly exhaust smoke. Quanda can provide you with various kinds of fans and they can be customized to meet your specific applications requirements.
