Smoke Exhauts

Panel-type smoke exhaust outlets are fire protection smoke exhaust devices installed on building walls or ceilings, primarily consisting of a faceplate, blades, and an actuator. They remain closed under normal conditions; in the event of a fire, they are activated by an electrical signal from the fire control center or via manual operation, causing the blades to swing open to create a smoke exhaust passage, which triggers the smoke exhaust fan to rapidly remove smoke. They feature a compact design and easy installation, allowing them to be directly recessed into walls or ceilings. They are suitable for mechanical smoke exhaust systems in locations such as stairwells, vestibules, and hallways. Some models are equipped with a 280°C high-temperature shut-off function to prevent smoke backflow, making them critical terminal devices in building smoke exhaust systems for achieving directed smoke discharge.
