DAMPER
FIRE DAMPER
HI AIR KOREA(HAK) A-Class FIRE & GAS DAMPERS for marine & offshore installations are type-certified based on Marine Equipment Directive 2014/90/EU and IMO Res. MSC.307(88). These dampers can be also supplied with ATEX Directive 2014/34/EU for explosive atmosphere installations
HAK H-Class FIRE & GAS DAMPERS are type-certified based on IMO 2010 FTP Code Part 3 with HC time-temperature curve specified in ISO 834-3.
Both A-Class and H-Class dampers can operate at temperatures between -40 ~ +60℃ but subject to change depending on the selected components. An open/close indication is visible on the damper enclosure side. The maximum duct pressure of damper operation is 5,000 Pa. The local control switch or valves can be supplied as an option.
- FEATURES
A-CLASS
- HAK FIRE & GAS DAMPERS can be manufactured to fit both rectangular and circular ducts. These dampers are equipped with quality frangible bulb to ensure that dampers will promptly close to eliminate the spread of fire & gas throughout ductwork. The standard frangible bulb shall break at a temperature of approx. 68°C. Other temperatures such as 93°C or 141°C can be provided upon request.
- The FIRE & GAS DAMPERS are equipped with opposed blades that are designed to minimize pressure loss and noise on the air system.
- FIRE & GAS DAMPERS can be fitted with electric or pneumatic actuators which shall include limit switches or proximity sensors that detect the position of the damper blades which in turn can be interfaced with monitoring and control system.
- The maximum size of the single type is 1,200 mm(W) and 1,400 mm(H). The pneumatic FIRE & GAS DAMPERS can be applied for mullion types, max. size of mullion types is 2,500 mm(W) and 2,100 mm(H).
ELECTRIC FIRE & GAS DAMPER (EFD / EFGD)
- The electric actuator requires 24 to 230 VAC/DC of electrical supply to open the damper blades.
The damper blades shall close when the power is cut-off.
PNEUMATIC FIRE & GAS DAMPER (PFD / PFGD)
- The pneumatic actuator requires a supply of 5~8 bar of clean/dry instrument air to open the damper blades. The damper blades shall close when instrument air is cut-off or pressure is too low.
H-CLASS
- The maximum size of the single type is 1,200 mm(W) and 1,200 mm(H). The standard frangible bulb shall break at a temperature of approx. 68°C or 93°C. FIRE & GAS DAMPERS can be fitted with only pneumatic actuators.
PNEUMATIC FIRE & GAS DAMPER (PFD / PFGD)
- The pneumatic actuator requires a supply of 5~8 bar of clean/dry instrument air to open the damper blades. The damper blades shall close when instrument air is cut-off or pressure is too low.
LEAKAGE RATE
- The spring type side seal is provided to achieve the EN 1751 based leakage classes given below.
