Introduction
In cleanrooms, both air showers and pass boxes are critical for contamination control. However, their functions are distinct, and choosing the wrong solution—or using only one—can compromise cleanroom integrity.
At PassBox MFG, we provide high-quality air showers and pass boxes, designed to work together or individually depending on your cleanroom workflow and GMP requirements.
Air Shower vs Pass Box: Key Differences
| Feature | Air Shower | Pass Box |
|---|---|---|
| Purpose | Decontaminates personnel | Transfers materials |
| Contamination Control | Removes particles from clothing | Prevents cross-contamination of items |
| Airflow | High-velocity HEPA-filtered jets | Static or laminar airflow (dynamic) |
| Doors | Interlocked for personnel entry | Interlocked for material transfer |
| Applications | Entry points, gowning rooms | Between cleanrooms of different grades |
Summary:
- Use air showers to protect cleanrooms from human-borne contamination.
- Use pass boxes to safely move materials without human entry.
- Together, they create a complete contamination control system.
Applications in Cleanrooms
Air Showers:
- Personnel decontamination before entering cleanroom
- Pharmaceutical labs, biotech research centers
- Electronics & semiconductor facilities
Pass Boxes:
- Transfer of raw materials, instruments, or samples
- Prevent cross-contamination between rooms
- Static or dynamic options depending on risk level
When to Use Each
Low-risk material transfer → Static pass box is sufficient
High-risk or sterile material transfer → Dynamic pass box
Personnel entering cleanrooms → Air shower is mandatory
Full contamination control → Combine air shower + dynamic pass box
