Smoke exhaust vents<\/span> (SHEV – Smoke and Heat Exhausting Ventilators<\/em>)<\/strong> as they are generally known, are devices with automatic and manual activation designed to exhaust smoke and hot gases in the event of a fire. The purpose of using smoke vents is both to limit human and property damage and to facilitate the intervention of firefighting teams in the event of a fire. Applications for smoke vents: commercial spaces such as hypermarkets, shopping malls, logistics parks, production halls, theaters, schools, and so on.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/welkins.eu\/wp-content\/uploads\/2019\/09\/Trapa.jpg” alt=”Trape de fum” title_text=”Trape de fum Welkins” align_tablet=”center” align_phone=”” align_last_edited=”on|desktop” _builder_version=”4.24.2″ animation_style=”flip” animation_direction=”top” border_radii=”on|4px|4px|4px|4px” box_shadow_style=”preset1″ locked=”off” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ custom_margin=”-40px||||false|false” collapsed=”on” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ text_font=”Open Sans||||||||” text_font_size=”16px” global_colors_info=”{}”]<\/p>\n \u200bWhen it comes to minimizing casualties or saving lives, it is well known that at least 90% of people exposed to a fire are not directly affected by the flames. Victims typically suffer from the toxic gases and hot air generated by the fire. These smoke vents (SHEV systems), like smoke exhaust windows, ensure the efficient evacuation of toxic gases inhaled by people during a fire and of the hot air that causes external and internal burns in the human body.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_5,3_5″ admin_label=”actionare electrica” _builder_version=”4.16″ collapsed=”off” global_colors_info=”{}”][et_pb_column type=”2_5″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_image src=”https:\/\/welkins.eu\/wp-content\/uploads\/2026\/04\/Sistem-electric-en-2.jpg” alt=”actionare electrica a trapelor de fum” title_text=”Sistem-electric-en-2″ _builder_version=”4.27.6″ border_radii=”on|4px|4px|4px|4px” box_shadow_style=”preset1″ global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ text_font=”Open Sans||||||||” text_font_size=”16px” global_colors_info=”{}”]<\/p>\n From the perspective of minimizing property damage, smoke extraction aims, on the one hand, to preserve the structural integrity of the building by removing hot air from the burning building; this helps maintain the lowest possible temperature inside, thereby preventing damage to the building\u2019s load-bearing structure. This aims to limit or eliminate the risk of the building collapsing until emergency response teams arrive.<\/p>\n On the other hand, the goal is also to preserve the integrity of the stored goods; it is important to note that the equipment and goods inside a burning building are not affected solely by the fire. They also degrade due to the hot air or the chemical compounds produced by combustion, which leads to the destruction of this equipment and these goods. Furthermore, the hot air in a burning room, if not vented through smoke vents or smoke exhaust windows, can cause stored goods to spontaneously combust, even those located at a considerable distance from the source of the fire.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_3,1_3″ admin_label=”actionare pneumatica” _builder_version=”4.16″ collapsed=”off” global_colors_info=”{}”][et_pb_column type=”2_3″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ text_font=”Open Sans||||||||” text_font_size=”16px” global_colors_info=”{}”]<\/p>\n Therefore, it is clear that SHEV smoke extraction systems must be implemented to preserve the structural integrity of the building and the integrity of the stored goods and equipment for as long as possible until fire crews arrive to extinguish the fire.<\/p>\n The third objective of smoke and ventilation dampers is to facilitate the intervention of firefighting crews in the event of a fire. It is important to note that firefighting crews require a safe environment to be able to advance inside the burning building. If the air is too hot, they cannot advance to carry out their work.<\/p>\n Moreover, the dense, black smoke produced by the fire results in zero visibility, so the response team will be unable to advance and locate the source of the fire, and firefighting efforts in this case would be carried out at random. This highlights the importance of installing Welkins smoke vents and smoke exhaust windows.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_image src=”https:\/\/welkins.eu\/wp-content\/uploads\/2026\/04\/Sistem-pneumatic-en-2.jpg” alt=”actionare pneumatica a trapelor de fum” title_text=”Sistem-pneumatic-en-2″ _builder_version=”4.27.6″ border_radii=”on|4px|4px|4px|4px” box_shadow_style=”preset1″ global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”ferestre” _builder_version=”4.16″ background_color=”#edf0f2″ custom_margin=”40px||40px||false|false” border_radii=”off||0vw||” locked=”off” collapsed=”on” global_colors_info=”{}”][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.16″ locked=”off” collapsed=”off” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.27.6″ text_font=”Open Sans||||||||” text_font_size=”16px” header_font=”||||||||” header_2_font=”||||||||” header_3_font=”Share Tech||||||||” header_3_font_size=”33px” header_3_line_height=”1.2em” text_orientation=”justified” locked=”off” global_colors_info=”{}”]<\/p>\n For automatic opening and closing of windows<\/strong><\/span>, we offer solutions for a wide variety of applications, which can be a viable alternative to smoke vents.<\/p>\n Depending on the type of project, we can choose from a wide range of systems, developed together with our partner, GEZE, for ventilation in case of fire<\/span> (RWA systems – Rauch und W\u00e4rmeabzugsanlagen<\/em>), daily ventilation or fresh air intake.<\/strong><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/welkins.eu\/wp-content\/uploads\/2019\/10\/fereastra-evacuare-fum-geze.jpg” alt=”Ferestre Desfumare Welkins” title_text=”Ferestre desfumare GEZE” align_tablet=”center” align_phone=”” align_last_edited=”on|desktop” _builder_version=”4.27.6″ border_radii=”on|4px|4px|4px|4px” box_shadow_style=”preset1″ locked=”off” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ custom_margin=”-36px||||false|false” collapsed=”on” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ text_font=”Open Sans||||||||” text_font_size=”16px” text_orientation=”justified” global_colors_info=”{}”]<\/p>\n Installed on aluminum profiles with glazing having different characteristics depending on the requirements of each individual project, The smoke extraction\/ventilation in the facade is efficient, also ensuring a pleasant appearance for the smoke extraction solution<\/strong> (sistem RWA).<\/p>\n Smoke control window actuators create a safe and beneficial indoor atmosphere.
