Fire dampers can be divided according to their uses and operating temperatures
Fire dampers (FHF): operating temperature: 70°C; 150°C specifically for kitchen exhaust fumes; normal state: normally open; automatically closed at high temperatures in case of fire; suitable for: air conditioning supply/return ducts, air ducts passing through fire protection zones.
Smoke exhaust fire damper (PYFH): operating temperature: 280°C; normal state: normally open; smoke exhaust operation, automatic shutdown when over-temperature occurs and linkage stops the fan; suitable for: main pipe of the smoke exhaust system, main pipe of the smoke exhaust fan inlet.
Smoke exhaust valve (PYF)/normally closed air supply valve: no temperature sensing fuse; normally closed, fire electric signal turns on smoke exhaust/air supply; suitable for: smoke exhaust branch pipes, smoke prevention zone air outlets, and pressurized air supply ducts.

In building ventilation and air conditioning systems, air ducts often pass through different floors, fire protection zones or equipment areas. If there is no reliable fire partition device, high-temperature smoke and flames may spread rapidly through the air duct when a fire occurs, affecting the fire safety of the building.
The fire damper can automatically close in the event of a high temperature fire, cutting off the air duct passage and reducing the risk of fire and smoke spread. It is a commonly used fire safety supporting product in ventilation systems of commercial buildings, hospitals, hotels, basements, industrial plants and public buildings. Choosing a fire damper with stable quality, reliable action and solid structure will help improve the safety and engineering reliability of the entire ventilation and air conditioning system.
When the temperature in the pipe reaches the set value, the temperature sensing device operates and the valve automatically closes, blocking the continued spread of flames and smoke through the air duct.
It can be widely used in supply air, return air, exhaust air and air conditioning duct systems, and is suitable for installation in building fire protection zones, machine rooms, duct wells and floor crossing locations.
The valve body is made of high-quality steel plates or stainless steel materials, with a solid structure and stable blades, and is suitable for long-term installation in ventilation duct systems.
After the valve is closed, it can reduce the passage of smoke and hot air, and improve the fire isolation effect of the air duct system.
The product can be configured with a temperature-sensing fuse device, manual reset, electric actuator or signal feedback device to meet the control and monitoring requirements of different engineering projects.
Different operating temperatures can be selected according to project requirements, and are commonly used in general ventilation and air conditioning systems, smoke prevention and exhaust systems and special working conditions.
The structure is reasonably designed and can be connected to rectangular or circular air ducts, which facilitates on-site installation, debugging and later maintenance and inspection.
Non-standard customization can be carried out according to customer drawings, air duct size, fire protection requirements, control methods and installation locations, suitable for engineering project needs in different countries and regions.
