The system of single-compartment steel, circular smoke extraction ducts in E600 120 (ho) S1500 single fire resistance class is intended to be used in the construction industry in a horizontal system as elements creating a smoke extraction ventilation system or combined ventilation, fulfilling at the same time the functions of general and smoke extraction ventilation, assuming that they serve only the compartment in which they have been installed. Systems serving one fire compartment may be independent systems or may be combined with a collective, multi-compartment system. The main task of the smoke extraction systems is to remove hot gases and smoke from the area covered by the fire in order to facilitate the evacuation of people and to enable the extinguishing action and the evacuation of people from the area at risk, while complying with the criteria of fire and/or smoke tightness specified under conditions of exposure to a temperature of 600°C.
SMOKE system single-compartment circular smoke extraction ducts have the following application areas:
