The FHF-W Gravity Fire Damper is a passive fire protection device designed for installation in through-wall and through-floor pipes of ventilation and air conditioning systems. Manufactured from stainless steel or galvanized steel, this damper requires no external power supply or electrical signal to operate. It relies entirely on blade gravity or spring force to close automatically in the event of a fire, effectively preventing the spread of flames and smoke through ductwork.

The FHF-W Gravity Fire Damper is widely used in commercial buildings where HVAC ducts penetrate fire-rated walls and floors. Typical applications include:
| Facility Type | Specific Application |
|---|---|
| Hotels | Fresh air and smoke exhaust ducts crossing fire zones on guest floors |
| Supermarkets | Central HVAC supply/return ducts penetrating fire walls |
| Commercial Complexes | Ventilation ducts crossing core walls and fire compartment partitions |
| Office Buildings | Air conditioning ducts passing through stairwell vestibules and shafts |
| Shopping Malls | Public area ventilation ducts crossing fire barriers above fire shutters |
| Hospitals | Clean air conditioning and exhaust systems crossing fire zones |
| Schools & Libraries | Central ventilation ducts crossing critical fire separations |
Fire valves are valves used to block the passage of smoke and flames from a fire area, and to meet the requirements of fire stability and fire integrity within a certain period of time. Our company has absorbed advanced production technologies from both domestic and international sources, combined with our years of research and development on fire valves, to optimize the design and improve the airtightness and flexibility of the valve body. This product has been tested and approved by the National Fire Equipment Quality Inspection Center.
When a building catches fire, the flames quickly spread along the ventilation and air conditioning system ducts, causing significant losses in many cases. In order to minimize the losses caused by fires, effective fire prevention and smoke control measures must be taken to control the spread of fire. The reasonable setting of fire dampers in ventilation, air conditioning, and smoke control systems plays an important role.
| Product Type | Description |
|---|---|
| Fire Damper Type | A fire damper refers to a device installed on the supply and return air ducts of ventilation and air conditioning systems. It is usually in an open state, but when a fire occurs, it automatically closes when the gas in the duct reaches 70℃. Within a certain period of time, it can meet the requirements of fire resistance stability and integrity, and play a role in smoke isolation and fire prevention. This category includes various products such as gravity fire dampers, fire control valves, fire vents, airtight fire dampers, smoke dampers, and electronic self-control smoke dampers. |
| Smoke Exhaust Valve Type | The smoke exhaust valve is used on the smoke exhaust system pipeline or the suction port of the smoke exhaust fan. It is usually in a closed state. When a fire occurs, the valve is manually or automatically opened through a fire alarm signal. According to the system function, it cooperates with the smoke exhaust. When the temperature of the smoke in the pipeline reaches 280℃, it automatically closes and can meet the requirements of fire resistance stability and integrity for a certain period of time, playing a role in smoke isolation and fire resistance. This category mainly includes smoke exhaust fire dampers, plate type smoke exhaust vents (for ceilings), smoke exhaust vents for vertical shafts, and other products. Fire dampers and smoke exhaust valves are important components in ventilation, air conditioning, and smoke control systems. |
| Air Volume Control Valve | Air volume regulating valve, also known as air damper, is an indispensable central air conditioning terminal accessory in ventilation, air conditioning, and air purification projects of industrial plants and civil buildings. It is generally used in air conditioning and ventilation system ducts to regulate the air volume of branch pipes, and can also be used for mixed regulation of fresh and return air. |
