A cleanroom is an enclosed space designed to maintain specific environmental standards through high-efficiency air filtration systems, precise temperature and humidity control, and differential pressure management, effectively regulating airborne particulate levels, airflow distribution, and climatic conditions. The structure utilizes anti-static, low-particulate materials and is equipped with isolation facilities such as air showers and pass-through chambers. Personnel must wear cleanroom garments and follow standardized purification procedures before entering. This controlled environment is critical in industries such as semiconductor manufacturing, biopharmaceuticals, and precision instrumentation, providing a reliable foundation for high-precision processes and sterile production. Through continuous particle monitoring and dynamic environmental adjustments, cleanrooms meet varying cleanliness requirements, ensuring production quality and the accuracy of experimental data.
