Cleanroom Pass-Through Box for Safe Material Transfer
A cleanroom pass-through box is designed for safe, efficient, and controlled transfer of small items between areas of different cleanliness levels. It reduces unnecessary personnel movement, minimizes door openings, and helps lower cross-contamination risks during cleanroom production and laboratory operations.
By combining interlocked doors, sealed chamber design, optional self-cleaning airflow, and sterilization functions, the pass-through box acts as a controlled material transfer station between clean and non-clean areas.
1. Core Functions
| Function | Working Principle | Customer Value |
|---|---|---|
| Safety Isolation | Electronic or mechanical interlock ensures that only one door can be opened at a time. | Prevents direct airflow exchange and helps maintain cleanroom pressure and cleanliness integrity. |
| Internal Self-Cleaning | A fan and HEPA filter can create clean airflow inside the chamber after both doors are closed. | Removes particles from transferred items and reduces contamination entering higher-class clean areas. |
| Efficient Transfer | Creates a dedicated material transfer channel through the cleanroom wall. | Reduces personnel entry frequency, saves time, and lowers contamination risks caused by human movement. |
2. Materials and Performance
| Component | Materials / Performance | Core Advantages |
|---|---|---|
| Chassis | SUS 304 stainless steel or electrostatically painted cold-rolled steel plate. | Corrosion-resistant, easy to clean, durable, and suitable for cleanroom use. |
| Doors | Sliding or swing-type doors, often with tempered glass viewing windows. | Good sealing, stable operation, and visual confirmation of transferred items. |
| Sealing Gasket | Silicone rubber or EPDM rubber gasket. | Improves airtightness, aging resistance, corrosion resistance, and service life. |
| Filtration System | Pre-filter and HEPA filter, with filtration efficiency ≥99.99% for particles ≥0.3 μm. | Provides clean airflow for chamber self-cleaning and particle removal. |
| Control System | Microprocessor control panel with power, self-cleaning, status indication, and optional UV sterilization. | Simple operation, customizable functions, and optional integration with facility systems. |
3. Key Performance Indicators
| Indicator | Description |
|---|---|
| Airtightness | Tight sealing between the door frame and door leaf helps reduce leakage and maintain cleanroom pressure stability. |
| Self-Cleaning Effect | The chamber can achieve high cleanliness after a preset self-cleaning cycle, typically within a short purification time. |
| Interlock Reliability | Prevents simultaneous opening of both doors to ensure cleanroom isolation and transfer safety. |
| Noise Control | Low-noise fan operation supports a quieter and more comfortable working environment. |
4. Common Specifications and Configurations
| Parameter | Common Specifications |

| Optional Features | UV germicidal lamp, self-cleaning cycle, audio-visual alarm, status indicators, and customized control logic. |
| Installation Method | Recessed installation for space-saving wall integration, or surface-mounted installation for faster setup. |
5. Typical Applications
Pass-through boxes are suitable for pharmaceutical cleanrooms, laboratories, medical device workshops, food and beverage cleanrooms, electronics manufacturing, precision assembly, PCB production, packaging areas, and other controlled environments requiring safe material transfer.
6. Customization Options
The pass-through box can be customized according to cleanroom layout, cleanliness level, transfer item size, chamber dimensions, interlock type, material selection, filtration configuration, UV sterilization requirements, and control system needs.
If you have specific application requirements, we can provide suitable selection advice and customized cleanroom transfer solutions.
