Dynamic Pass Box vs. Static Pass Box: Key Differences and Applications
Créé le 04.17
Pass boxes are critical for contamination control in pharmaceuticals, food processing, and electronics manufacturing. But should you choose a static or dynamic pass box? Static models are cost-effective for low-risk transfers, while dynamic pass boxes with HEPA filtration ensure ISO 5 cleanliness for sterile environments. This guide compares their features, costs, and compliance with GMP/ISO standards—helping you select the right solution
1. Static Pass Box
A static pass box is a non-powered transfer device that relies on manual operation. Its key features include:
No Airflow: Lacks fans or filters, relying on physical isolation to reduce contamination risks.
Simple Structure: Typically made of stainless steel or durable plastic, with a lower cost.
Applications: Suitable for low-cleanliness zones or non-sensitive items (e.g., packaging materials, tools).
Operation: Features interlocked doors to prevent simultaneous opening, ensuring one-way transfer.
Advantages
✔ Cost-effective, low maintenance✔ Ideal for low-risk environments✔ No power required, energy-efficient
2. Dynamic Pass Box
A dynamic pass box is equipped with an air purification system (e.g., HEPA filters) and fans to actively control airflow and maintain cleanliness. Its core features include:
Air Filtration: Built-in HEPA filters to remove particles and microorganisms.
Airflow Control: Supports unidirectional or bidirectional airflow to block contaminants.
Applications: Used in industries with strict cleanliness standards (e.g., food Industry,pharmaceuticals, labs, electronics).
Advanced Features: Some models offer UV sterilization, touchscreen controls, etc.
Advantages
✔ Ensures higher cleanliness✔ Complies with GMP, ISO standards✔ Customizable for industry needs
3. Key Comparison
Feature | Static Pass Box | Dynamic Pass Box |
Airflow | None | HEPA-filtered |
Cleanliness | Low | High |
Cost | Lower | Higher |
Industries | Warehousing, Food Packaging | Food Industry,Pharma, Labs, Semiconductors |
Maintenance | Low | Filter replacement needed |
4. Conclusion
For low-cleanliness needs and budget constraints, a static pass box is a practical choice.
For high-cleanliness environments (e.g., sterile production), a dynamic pass box offers superior protection.

FAQ:
Q: Can a static pass box be used in a GMP cleanroom?
A: No, static pass boxes lack HEPA filtration and are unsuitable for GMP-grade environments. Dynamic pass boxes with ISO 14644 compliance are required.
Q: How often should HEPA filters in a dynamic pass box be replaced?
A: Typically every 6-12 months, depending on usage and air quality monitoring.
Q: What is the price difference between static and dynamic pass boxes?
A: Static pass boxes cost $500-$2,000, while dynamic models range from $3,000-$10,000+ due to advanced filtration and airflow control.
