Automatic Smoke Curtains are advanced smoke control curtain systems designed to limit, contain and channel smoke movement inside buildings during a fire emergency.
Unlike fire curtains, whose primary purpose is to provide fire compartmentation against direct fire exposure, an automatic smoke curtain primarily supports smoke management. When activated by a fire alarm or smoke detection signal, the curtain automatically descends from a concealed headbox to a predetermined design position, helping form smoke reservoirs, control smoke migration and direct smoke toward designated extraction areas.
Manufactured by Huadun Door Industry, a professional Automatic Smoke Curtain manufacturer, smoke curtain manufacturer and OEM supplier, the system combines heat-resistant flexible curtain fabric, roller assembly, compact headbox, motorized drive and intelligent fire alarm interface into a project-specific smoke control solution.
Automatic deployment allows the curtain to remain concealed during normal building operation while becoming part of the building's smoke management strategy during an emergency. This makes automatic smoke curtains particularly suitable for atriums, escalators, stair openings, shopping malls, airports and other large open spaces where permanent smoke barriers would interfere with architectural design or daily circulation.
Huadun provides customized Automatic Smoke Curtains, Active Smoke Curtains, Smoke Control Curtain Systems and OEM manufacturing for international projects.
Smoke is one of the greatest hazards during a building fire, reducing visibility, affecting evacuation routes and hindering firefighting operations. An Automatic Smoke Curtain is designed to control smoke movement as part of a building's overall smoke management strategy.
Installed above an opening or concealed within the ceiling, the Automatic Smoke Curtain remains stored inside a compact headbox during normal operation.
When the fire alarm or smoke detection system is activated, the Automatic Smoke Curtain automatically deploys to a predetermined smoke-control height, creating smoke reservoirs or smoke channels while maintaining the required clear zone below where permitted by the building's fire strategy.
By forming a continuous smoke barrier, the Smoke Control Curtain helps contain smoke, reduce smoke migration and direct smoke toward mechanical or natural smoke extraction systems, improving smoke compartmentation and evacuation safety.
Unlike a fire curtain, an Active Smoke Curtain is specifically designed for smoke containment rather than direct fire resistance and should be selected according to the building's smoke-control strategy.
Huadun Door Industry manufactures customized Automatic Smoke Curtain and Smoke Control Curtain systems for different opening sizes, curtain drops and project-specific smoke management requirements.
The Automatic Smoke Curtain remains concealed inside the headbox during normal building operation and automatically deploys when it receives a signal from the fire alarm or smoke detection system.
This automatic operation allows the Smoke Control Curtain to provide effective smoke management only when required while preserving the building's open architectural design.
The Automatic Smoke Curtain forms a continuous smoke barrier beneath the ceiling to control smoke movement during a fire emergency.
It helps to:
● Contain smoke within designated zones
● Create smoke reservoirs
● Channel smoke toward smoke extraction systems
● Reduce smoke migration into adjacent areas
This improves smoke compartmentation and supports safer evacuation.
Unlike many fire curtains, an Automatic Smoke Curtain does not always descend to the floor.
Instead, it deploys to a predetermined smoke-control height based on the building's smoke management strategy. This design controls the upper smoke layer while maintaining a clear space below where permitted.
The Automatic Smoke Curtain is stored inside a compact headbox and can be installed above openings or concealed within suspended ceilings.
When retracted, the Smoke Control Curtain has minimal visual impact, making it ideal for modern commercial buildings, shopping malls, airports and other open-plan spaces.
The Automatic Smoke Curtain uses lightweight, heat-resistant smoke barrier fabric designed to control smoke and hot gases.
Its flexible construction allows large barriers to be stored compactly while providing reliable smoke barrier performance for commercial and industrial applications.
The Active Smoke Curtain can be integrated with mechanical or natural Smoke and Heat Exhaust Ventilation (SHEV) systems.
By creating defined smoke zones, the Smoke Control Curtain directs smoke toward designated exhaust points, improving the overall efficiency of the building's smoke management system.
For wide openings, the Automatic Smoke Curtain can be configured with single or multiple roller systems to suit different project requirements.
Huadun provides customized solutions for various opening widths, curtain drops and installation conditions, making the system suitable for large commercial and public buildings.
As a professional Automatic Smoke Curtain manufacturer, Huadun offers OEM and customized production based on:
● Opening width
● Curtain drop height
● Ceiling and installation conditions
● Fire alarm interface
● Smoke control strategy
● Control system requirements
Each Automatic Smoke Curtain is engineered to integrate with the building's overall smoke management design, providing reliable performance for commercial, industrial and public construction projects.
● Heat-resistant smoke curtain fabric
● Roller assembly
● Compact headbox
● Motorized drive system
● Automatic Smoke Curtain controller
● Fire alarm / smoke detection interface
During normal operation, the Automatic Smoke Curtain remains concealed inside the headbox without affecting the building's appearance or daily circulation.
1.The fire alarm or smoke detection system sends an activation signal.
2.The Automatic Smoke Curtain deploys automatically to the predetermined smoke-control height.
3.A continuous smoke barrier is created to contain and channel smoke.
4.The Smoke Control Curtain directs smoke toward the designated smoke extraction area.
5.After the system is reset, the curtain returns to its standby position.

An Automatic Smoke Curtain is a motorized smoke control curtain that remains concealed during normal building operation and automatically deploys when activated by a fire alarm or smoke detection system. It is designed to contain and channel smoke, helping improve evacuation safety and smoke management.
An Automatic Smoke Curtain is designed to control smoke movement, while a fire curtain is designed to provide fire compartmentation and resist direct fire exposure.
An Active Smoke Curtain helps create smoke reservoirs and directs smoke toward extraction systems, whereas a fire curtain primarily prevents the spread of flames and heat.
