Description

Technical Field

[0002] Fire dampers are an important fire-fighting facility, mainly used to prevent fire from spreading in ventilation and air-conditioning systems inside buildings or equipment. Fire dampers are installed on air ducts of ventilation and air-conditioning systems that are suitable for fire protection requirements. When a fire occurs, the fire dampers can be quickly closed to isolate the fire source and prevent fire and smoke from spreading to other areas through the air duct, thereby protecting the safety of people and property.
