Laminar airflow ceiling is an essential purification device in modern hospital operating rooms. Based on leading leak-blocking layer technology and clean air supply ceiling systems, it optimizes airflow distribution to ensure Class 100 cleanliness at the supply surface. Widely used in clean operating rooms, clean wards, and clean animal facilities. Constructed with sheet metal and baked enamel finish. With rapid advances in medical science, surgical techniques demand ever-higher cleanliness standards. Class 100 laminar flow operating rooms are ideal. However, effectively managing air colony counts to meet both卫生部 hygiene standards and clean operating room grades remains an under-researched topic. This device uses air purification technology to control microbial contamination, achieving suitable air cleanliness for various surgeries while providing optimal temperature and humidity, creating a clean, comfortable surgical environment.
