SAF Series
SAF Series fans are specifically designed for the ventilation of metro lines and for the transverse ventilation of road and rail tunnels.
They can be controlled by sensors and inverters for optimal efficiency and for temperature and pollutant control, and are certified for the extraction of hot smoke up to 400°C in the event of an emergency.
Technical Characteristics of SAF Fans
Type: Axial fans for ventilation in tunnels, metros and mines.
