  • Pharmaceuticals are special products that directly impact human health and are therefore subject to extremely stringent requirements throughout the production process. Clear regulations govern every aspect—from raw materials, production procedures, and equipment to software and personnel operations.

    To prevent contamination of drugs and packaging materials during manufacturing, environmental control and standardized processes must meet strict quality standards. In this context, the application of air cleanliness technology is particularly critical. It effectively controls both biological and non‑biological particles through multi‑stage air filtration, ensuring that air entering the cleanroom meets specified requirements. Personnel and material purification procedures isolate or eliminate external contamination. Parameters such as airflow organization, pressure differentials, and air change rates work together to suppress microbial and particulate pollution. Additionally, any potential quality impairments caused by light, odor, or relative humidity are eliminated, thereby minimizing the risk of contamination throughout the drug production process.
