In cleanroom environments, contamination control is critical. Whether in pharmaceuticals, biotechnology, electronics manufacturing, or healthcare, even minor pollutants can compromise product quality or experimental accuracy. The Pass Box serves as an essential cleanroom device, enabling safe and efficient material transfer while maintaining a contamination-free environment.

Why Are Pass Box Indispensable in Cleanrooms?

1. Prevents Cross-Contamination & Maintains Cleanliness

The core requirement of a cleanroom is controlling airborne particles and microorganisms. Pass Box utilize a dual-door interlock system, ensuring that the inner and outer doors cannot open simultaneously. This prevents external contaminants from entering while stopping internal particles from escaping.

2. Improves Efficiency & Reduces Personnel Traffic

Frequent personnel movement increases contamination risks. Pass Box allow tools, samples, or materials to be transferred without compromising the clean environment, reducing human traffic and improving operational efficiency.

3. Compatible with Different Cleanliness Class Zones

Pass Box can be equipped with HEPA filters or UV sterilization lamps, ensuring transferred items meet various cleanliness standards (e.g., ISO Class 5, ISO Class 8). They are widely used in pharmaceuticals, laboratories, food production, and more.

4. Complies with GMP/FDA Regulations

In pharmaceutical and medical industries, GMP (Good Manufacturing Practice) and FDA (U.S. Food and Drug Administration) impose strict cleanroom management standards. Pass Box help companies meet compliance requirements and avoid regulatory risks.

5. Flexible Configurations for Different Needs

Pass Box come in multiple types, including:

Standard Mechanical Interlock Pass-Through (ensures doors do not open simultaneously)

Electronic Interlock Pass-Through (alarm function prevents misuse)

Sterilization Pass-Through (built-in UV or ozone disinfection)
Users can select the most suitable model based on their needs.

Conclusion

Pass Box are not only crucial for material transfer in cleanrooms but also vital for maintaining contamination control, improving productivity, and ensuring regulatory compliance. For industries requiring strict contamination prevention, choosing the right pass-through window is essential to guarantee safety and efficiency in production processes.
