Our company manufactures panel-type smoke vents—also known as remotely controlled smoke vents or smoke dampers—which are specialized devices installed in suspended ceilings or wall surfaces within building fire‑protection smoke‑exhaust systems. Normally closed, these vents are opened upon activation by the fire‑alarm linkage system during a fire to exhaust indoor smoke, thereby facilitating safe evacuation and supporting firefighting and rescue operations. They are widely used in shopping malls, office buildings, underground parking garages, industrial plants, and other facilities.
