High reliability: Tunnel fans usually adopt high-quality materials and advanced manufacturing processes, and have high reliability and stability. They are able to operate stably for a long time in harsh tunnel environments.
High efficiency and energy conservation: New types of tunnel fans, such as the FD tunnel opposed axial fans and forced-inlet fans, are characterized by high efficiency and obvious energy-saving effects. According to different ventilation resistance requirements, they can be used as a whole unit or in different stages, reducing the power consumption of ventilation.
Bidirectional operation: Some tunnel fans, such as bidirectional jet fans, can switch between forward and reverse rotation and reach the rated speed of the fan within 30 seconds to meet the ventilation and smoke exhaust requirements of the tunnel under different working conditions.
Low noise: In places with high requirements for noise control, mufflers can be added to reduce noise, and the noise of the fan can be controlled within 80 decibels, reducing the impact on the environment inside the tunnel and the surrounding residents.
