Smoke extraction systems are used to remove smoke, heat and toxic gases during a fire, improving conditions for evacuation and extinguishing. These systems provide better visibility and reduce the risk of suffocation, thereby increasing the safety of people in buildings. They are used in residential, commercial and industrial buildings, especially in areas with high traffic.

Systems can be natural, using openings and ventilation ducts, or mechanical, using fans and sensors. Their correct installation and regular maintenance are essential for effective action in emergency situations. The main purpose of a smoke extraction system is to slow the spread of a fire and facilitate the intervention of the fire services.
