Roof smoke exhaust fans type mcr Pasat with radial rotor are designed for removing smoke and hot air from rooms during fire, and for comfort ventilation. They may feature one-speed or two-speed engines and combine comfort function with fire function, e.g. for ventilating and de-smoking underground garages, malls, production halls.
Smoke exhaust fans facilitate evacuation of humans and equipment from rooms covered by fire; they allow for a quicker and more effective firefighting operation, also protecting the building structure and its equipment from high temperature, and preventing propagation of fire, fire gases and smoke to neighbouring fire zones. The devices are adapted for outdoor work in vertical working position.
