Multi-blade Fire Damper, FHF-WS-K-WXH (ф) KZCH
This multi-blade fire damper is usually installed in ventilation system, air conditioning system, fire rated walls or floors. The fusible link inside this fire damper will melt when the heat of surrounding environment reaches 70 °C (158 °F), and later the blades will shut down. Electric signal device can be installed based on your demands.
Dimensions: L=wall thickness+100 or H/W+50
Fire Damper, FHF-WS-K-WXHK, FHF-WS-K- (ф) K
This fire damper can be installed in the air ducts of ventilation or air conditioning system to meet requirements of smoke or fire resistance. Blades should be shut down or opened manually to restrict the passage of fire when the environment temperature reaches 70 °C (158 °F). Signals will be sent when blades are shut down. Access door and hanging parts can be installed based on your demands.
Fusible link rating: 70 °C
Fire resistance rating: 1.5 h
Resistance coefficient: < 0.5
Fire Damper, FHF-WSDC-K-WXHK, FHF-WSDC-K- (ф) K
This fire damper can be installed in the air ducts of ventilation or air conditioning system to meet requirements of smoke or fire resistance. Blades should be shut down or opened manually to restrict the passage of fire when the environment temperature reaches 70 °C (158 °F). The blade will be shut down automatically by control panel when smoke or rising temperature is detected by sensors. Access door and hanging parts can be installed based on your demands.
Fusible link rating: 70 °C
Fire resistance rating: 1.5 h
Resistance coefficient: < 0.5
Actuator voltage: DC 24V
Electric current: < 0.5A
Fire Damper, FHF-WS-FK-WXHK, FHF-WS-FK- (ф) K
This fire damper can be installed in the air ducts of ventilation or air conditioning system to meet requirements of smoke or fire resistance. Blades should be shut down or opened manually to restrict the passage of fire when the environment temperature reaches 70 °C (158 °F). The blade will be shut down automatically by control panel when smoke or rising temperature is detected by sensors. Angle of damper blades is adjustable in five levels between 0° and 90°. Access door and hanging parts can be installed based on your demands.
