FHF Fire Damper Series
Product Introduction:
Fire dampers are installed on the supply and return air ducts of ventilation and air conditioning systems. They are normally open and automatically close when the air inside the duct reaches 70°C in the event of a fire. They meet fire resistance stability and integrity requirements for a certain period of time, acting as a smoke and fire barrier. They include gravity fire dampers, fire control dampers, fire vents, airtight fire dampers, smoke and fire dampers, and electronically controlled smoke and fire dampers, among other products.
Structural characteristics:
Fire protection dampers are mainly composed of a valve body, blades, temperature sensing components, and reset mechanisms.
1. Valve body: Made of heat-resistant, corrosion-resistant galvanized steel sheets or stainless steel; it has a rectangular structure and can be customized in shape and size to match the duct system for proper installation.
2. Blades: Multiple rotating blades with various rotation angles; they feature high-strength sealing properties and effectively block flames and smoke.
3. Temperature sensing components: Various types of temperature-sensing fusible devices are available, utilizing fusible alloys or memory alloys to trigger the valve when the set temperature threshold is reached.
4. Reset mechanisms: These can be either spring-driven or powered by electric/manual actuators.
Product Information:
| Product name | Model | Function | State |
| Self weight fire damper | FHF-W | The fuse operates at 70 ℃/150 ℃, and the valve automatically closes under the force of blade gravity or spring force. | normally open |
| Smoke and fire dampers | FHF-W-K | When the fuse is activated at 70 ℃/150 ℃, the valve automatically closes. Manually turn on or reset. | normally open |
| Fire control valve | FHF-WS-FK | The 70 ℃ fuse will activate and the valve will automatically close. Manually turn on or reset. Adjust the air volume in five levels within the range of 0-90 °. Output valve closing signal, whether to output signal according to user needs. | normally open |
| Electric fire damper | FHF-WSDc-K | Manually close or reset When the airflow temperature reaches 70 ℃, the fuse will activate to automatically close the valve. Output valve closing signal. | normally open |
| Electric fire control valve | FHF-WSDc-FK | Manually close or reset; When the airflow temperature reaches 70 ℃, the fuse will activate to automatically close the valve. Output valve closing signal. It has air volume adjustment function. | normally open |
| Fire damper | FHF-WSDc-K | When the airflow temperature reaches 70 ℃, the fuse will activate to automatically close the valve. The valve can be closed through a DC24V power supply. Manually turn on or reset. Output valve closing signal, which can be interlocked with other devices. | normally open |
| Fireproof vent | FHFK-W | It can be used as an air outlet to adjust the direction of the air supply flow. It is usually opened when the air temperature reaches 70 ℃. Under the drive of shape memory alloy or the action of temperature fuse, the valve is closed. | normally open |
| Fully automatic fire damper | FHF-WSDcDj-K | When the airflow temperature reaches 70 ℃, the fuse will activate, causing the valve to automatically close. Signal can be activated through DC24V Quickly close the valve. Manually turn on or reset. After the valve is closed, it can be reset to the open state through a DC24V power supply. | normally open |
