TAVR2e-12.5 is a high temperature tunnel fan, with a reversible built, dampers on suction and pressure side, and girders for the installation into tunnel tube. Fan rotor is connected directly to the electro motor. The tunnel fan is applied with longitudinal tunnel ventilation, for maintaining the required air quality, controlling fire propagation, facilitating fire brigade access to the fire site and smoke extraction tunnel. The whole construction is corrosion protected through hot galvanizing and coated with finishing paint.
