The Advantages of multi-leaf exhaust fans

Now the exhaustfan are very important for homelife.And The multi-leaf Exhaust Fan is a small ventilation configuration with a hot take-up unit for the room. Press on the wall or the top plate to use as a pressurized air supply port for the smoke exhaust port or smoke prevention system. When the fire occurs, resolve the power supply DC24V or manually open the valve. According to the results of the system, smoke or prevent the smoke front room. Air supply, when the temperature of the flue gas reaches 280 °C, the valve is closed again to isolate the airflow. The multi-leaf exhaust vent is a small ventilation configuration with a hot take-up unit for the room. The tension control parameters are selected as air volume, static pressure loss, total air outlet pressure, input power, effective air exchange rate, interchange efficiency, and noise.

Now the middle air-conditioning systerm , in order to reduce costs, the indoor space is closed regardless of planning or operation. During the air-conditioning operation period, the structure is tight and airtight. The indoor atmosphere is separated from the outdoor environment by more than 90% of the time. The indoor odor is difficult to crowd out. In an emergency environment, we will think that it is difficult to breathe and vomit. The birth of the multi-leaf exhaust vents can handle the above problems for us. It is mainly composed of valve body, valve plate, bushing, remote control actuator and grille panel. It has normal normally closed, electric and manual opening; Start signal; manual reset is off. The 280 °C temperature sensor operates and the valve closes again. The thin mechanism is used to reduce the size of the operation box and increase the effective ventilation and smoke exhaust area.
