English version machine-translated from the Vietnamese original — under review.
On 27 August, at the Fire Safety Research and Testing Center of the Vietnam Institute for Building Science and Technology (IBST), NSCA successfully tested an EI damper with a length of L300, installed entirely within the fire compartment and using a linear actuator, suitable for installation at corridor branches connected to the vertical duct shaft, under the ON-WALL, WITHIN-THE-FIRE-COMPARTMENT installation scope. The damper provides fire integrity, insulation and smoke control (EIS) and can be extended with a blade-angle positioner to balance airflow in systems designed for combined Supply/Exhaust, functioning as a VCD.
This is the first time NSCA has tested an EI damper located entirely within the fire compartment, an extremely demanding test. The successful testing of this type of fire damper is a major step forward in NSCA's product research and development, giving the market more convenient options for the design, installation and operation of fire protection systems in accordance with QCVN06:2021/BXD.
