Dynamic Pass Box vs. Static Pass Box: Key Differences and Applications
创建于04.17
In logistics and warehouse management, a pass box is a common device used to transfer items safely between areas of different cleanliness levels, preventing cross-contamination. Depending on their operation mode, pass boxes are mainly categorized into Dynamic Pass Boxes and Static Pass Boxes. This article explores their differences to help you choose 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.
