Cleanliness requirements: Pharmaceutical production workshops need to meet strict cleanliness standards (such as ISO 14644-1 standard) to prevent microbial and particulate contamination.

Application scenarios: Clean doors and windows are used to isolate areas with different cleanliness levels to ensure that high-cleanliness areas are not affected by low-cleanliness areas.

Function: Prevent external pollutants from entering, maintain a positive pressure environment in the workshop, and ensure that air flow meets cleanliness requirements.
