Product Description
Our company's system selection and design model, which is based on vector optimization and aerodynamic models, is the SDF series tunnel fan. Based on the assumption that ventilation requirements are met, a sensible fan/dryer arrangement maximizes the fan's operational efficiency under all operating situations and allows the client to save money on the fan purchase price multiple times. A frequency conversion control system comes standard with every unit. The ventilator may be fully customized to satisfy the flow and pressure combination needs of various altitude circumstances by combining it with different types of main blades and guiding blades.
Extremely lengthy tunnels and tunnels with narrow cross-sections that are unable to use thicker ventilation ducts can be ventilated using SDF series tunnel fans. This product line is appropriate for ventilating extremely long tunnels and features an efficient multi-stage series combination structure. In order to achieve the maximum pressure and meet the requirements during challenging times, this product is made up of three, four, and five phases, respectively. With minimal noise, they can also be employed in single-stage or counter-rotation to guarantee construction safety and environmental protection. It is the best option for building highways, special ventilation systems for railroads, and hydropower projects.
Super-long and super-large tunnels, as well as local ventilation in water conservation and hydropower projects, railroads, highways, and subways, are the primary applications for SDF series tunnel fans. The recently created "multi-stage variable speed" series of ventilators designed specifically for tunnels is more appropriate for the construction of lengthy and expansive tunnels and has superior energy-saving capabilities.
