The SDF series tunnel fan is our company's system selection and design model based on the aerodynamic model and vector optimization. On the premise of ensuring ventilation needs, through reasonable fan/dryer configuration, the operating efficiency of the fan in all working conditions is optimized, and the energy-saving effect of the fan purchase cost is achieved several times for the customer. All products are equipped with a frequency conversion control system as standard. The ventilator can be combined with multiple types of main blades and multiple types of guide blades to achieve tailor-made full-condition customization to meet the flow and pressure combination requirements of different altitude conditions.
SDF series tunnel fans can be used to solve ventilation difficulties in extremely long tunnels and tunnels with small cross-sections that cannot use thicker ventilation ducts. This series of products has an optimized multi-stage series combination structure and is suitable for ventilation of ultra-long tunnels. This product is composed of three, four, and five stages respectively, all of which are put into operation to reach the highest pressure and meet the use in difficult periods. They can also be used in single-stage or counter-rotation to ensure construction safety and protect the environment with low noise. It is an ideal choice for highways and special ventilation equipment in railway and hydropower project construction.
SDF series tunnel fans are mainly used in super-long and super-large tunnels and local ventilation in railways, highways, subways, water conservancy hydropower projects, etc. In particular, the newly developed "multi-stage variable speed" series of tunnel-specific ventilators are more suitable for long and large tunnel construction and have better energy-saving effects.
