The fresh air booster cabinet is widely used in many scenarios with high requirements for air quality and air pressure control due to its ability to introduce filtered fresh air and increase indoor air pressure to prevent external pollution from seeping in. Specifically, it is as follows:
The medical and health field
The key areas of the hospital: The operating room requires a strictly sterile environment. The fresh air booster cabinet can remove bacteria and particles in the air through multi-stage filtration and maintain positive pressure inside the room to prevent unclean air from outside from entering and reduce the risk of surgical infection. Areas with high requirements for air cleanliness, such as ICU wards and delivery rooms, also rely on it to provide continuous, clean, fresh air. In addition, in hospital pharmacies and testing laboratories (such as microbiology laboratories), the use of fresh air booster cabinets can prevent impurities in the air from affecting the quality of drugs or experimental results.
The field of industrial production
In the precision manufacturing industry, in microelectronics, semiconductors, hard disk manufacturing, LED optoelectronics, and other industries, even the tiniest dust and particles during the production process can lead to product scrapping. The fresh air booster cabinet can deeply filter the introduced air (some are equipped with high-efficiency filters) while maintaining positive pressure in the workshop to prevent external pollutants from entering and ensure the cleanliness of the production environment.
In the biopharmaceutical industry, the production of drugs has extremely high requirements for the sterility and air cleanliness of the environment. The fresh air booster cabinet can filter microorganisms, dust, and other substances in the air, providing clean air that meets GMP standards for fermentation, formulation, and other processes, ensuring the quality and safety of drugs.
The food processing industry: Food production workshops (such as baking, dairy products, canned food processing, etc.) need to avoid bacterial and dust contamination of food. The fresh air booster cabinet can purify the introduced air and prevent contaminants from outside the workshop from entering through positive pressure, reducing the risk of food spoilage and contamination, and meeting food hygiene standards.
Civil and public buildings
Residential and office buildings: In modern buildings with good airtightness, fresh air booster cabinets can introduce filtered outdoor fresh air to replace indoor polluted air (such as formaldehyde, CO₂, cooking fumes, etc.), improve indoor air quality, and enhance the comfort of living and working. They are especially suitable for areas with frequent smog or poor air quality.
Public places such as shopping malls and hotels: These places are densely populated and have a high demand for air circulation. The fresh air booster cabinet can continuously provide clean fresh air, avoiding air turbidity and odor accumulation. At the same time, through reasonable air pressure control, it optimizes the indoor air circulation.
Fire protection and special ventilation systems
Fire-fighting pressurized air supply: In the stairwells, anterooms, and other evacuation passages of high-rise buildings, the fresh air pressurized cabinet can be used as a fire-fighting pressurized air supply device. When a fire occurs, it supplies air into the passage to create positive pressure, preventing smoke from entering and buying time for personnel evacuation and fire rescue.
Purification air conditioning supply air: In some places that adopt purification air conditioning systems (such as clean laboratories and electronic factories), when the air volume or air pressure of the air conditioning system is insufficient, the fresh air booster cabinet can be used as a supply air device to supplement clean air and maintain the required air pressure balance of the system.
In addition, the fresh air booster cabinet can also be applied in laboratories (such as chemical laboratories and scientific research laboratories), data centers (to ensure the cleanliness and ventilation of the equipment operating environment), and other scenarios. According to the requirements of different scenarios, its parameters, such as filtration grade, air volume, and air pressure, can be flexibly adjusted.
