Cleanliness requirements: The production of electronic components needs to be carried out in a highly clean environment, usually requiring the high cleanliness level in the ISO 14644-1 standard (such as ISO level 5 or higher).

Application scenarios: Clean doors and windows are used to isolate dust-free workshops from the external environment, as well as between areas of different cleanliness levels.

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