ISO 14644-1 is the most widely used international standard for classifying air cleanliness. In Vietnam, Pharmaceutical and Electronics factories all comply with this standard.
1. Common cleanliness levels
- ISO Class 5 (equivalent to old Class 100): Extremely clean. Application: Organ transplant operating room, semiconductor wafer production. Requires ULPA or HEPA filter covering the ceiling.
- ISO Class 7 (equivalent to old Class 10,000): Popular. Application: Common operating rooms, medical equipment production, functional foods.
- ISO Class 8 (equivalent to old Class 100,000): Applications: Packaging areas, clean corridors, pharmaceutical packaging production.
2. What support does VAF provide you?
To achieve these levels, gas selection is key. VAF provides a complete set of solutions from Primary Filter (G4) -> Bag Filter (F8) -> HEPA Filter (H13) and FFU equipment to ensure the number of air exchanges (Air Changes Per Hour - ACH) meets the requirements of each ISO level.
