Human and Purification introduces you to the classification of laminar flow operating rooms and the characteristics of a sterile laminar flow operating room.
Laminar operating room features
1. The number of bacteria in the operating room is low.
2, for comfortable airflow (indoor temperature can be 15-25 ° C, humidity can be adjusted between 50-65%).
3. The positive pressure airflow (+23-25Pa) in the operating room prevents the entry of external pollution.
4, the operating room air is fresh, clean, and the working environment is comfortable.
