Working principle of fresh air booster cabinet

Air input
The work of the fresh air booster cabinet begins with the air input link. It introduces outdoor air into the equipment through a ventilation duct connected to the outside. Just like we open the window to let the outside air enter the room, this "window" of the fresh air booster cabinet is connected to a special pipeline, and it is more controllable. These pipes are like an "air channel", which continuously delivers outdoor fresh air to the fresh air booster cabinet, providing "raw materials" for the subsequent air treatment link.
Multiple filtration purification
When the outdoor air enters the fresh air booster cabinet, it enters the crucial filtration link. In this stage, the air passes through different filters. The first is the primary filter, which is like a "coarse screen" that can intercept larger particles of pollutants in the air, such as dust, hair, catkins, and so on. If these large particles of pollutants enter the room directly, they will not only affect the air quality but also may cause damage to the furniture and electrical appliances in the room.
After the initial filtration of the primary filter, the air will continue to enter the intermediate filter. The filter is more accurate and can capture smaller particles, such as pollen, mold spores, and some bacteria. For those who are allergic to pollen, the effect of the filter is particularly important, it can effectively reduce the concentration of indoor pollen, and reduce allergy symptoms.
In some places with high air quality requirements, the fresh air booster cabinet will also be equipped with high-efficiency filters. Hepa filters can filter out extremely small particles, including PM2.5, viruses, etc., and can even reach a filtration efficiency of more than 99%. In hospital operating rooms, laboratories, and other places, HEPA filters provide a clean air environment for medical staff and experimentalists, effectively reducing the risk of infection and experimental error.
In addition to these physical filtration methods, some fresh air booster cabinets will also use activated carbon adsorption and other technologies to remove odors and harmful gases in the air. Activated carbon has a rich pore structure, and can absorb formaldehyde, benzene, TVOC, and other harmful gases, as well as the odor in the air, so that the air into the room is more fresh and pleasant.
Strong pressure conveying
After the completion of filtration and purification of the air, it also needs to be transported to all corners of the room. However, in this process, due to the length of the ventilation pipe, the degree of bending, and the friction of the inner wall of the pipe, the airflow will be subjected to a certain resistance. To overcome this resistance, so that the fresh air can reach the room smoothly, the fresh air booster cabinet needs to play its pressurization function.
There is a powerful fan installed inside the fresh air booster cabinet, and the fan obtains kinetic energy through high-speed rotation, thereby increasing the pressure of the air. Just like we use a pump to pump up a bicycle tire, the fan constantly "pumps" the air, allowing it to move quickly and steadily through the pipe. The speed and power of the fan can be adjusted according to the actual needs to meet the ventilation needs of different places and different areas. For example, in large shopping malls, office buildings, and other places with large spaces, large power fans are needed to provide sufficient air volume and pressure to ensure that fresh air can cover every corner.
In the process of pressurized transportation, the fresh air booster cabinet will also monitor and adjust the airflow, pressure, and other parameters through some intelligent control systems. These control systems are like the "brain" of the fresh air booster cabinet, which can automatically adjust the working state of the fan according to the changes in the indoor and outdoor environment and the needs of the user, to ensure that the transmission effect of the fresh air is always in the best state.
