Application of AI in the Pass Box System for Cleanrooms

I. Introduction to Pass Box in Cleanrooms

What is a Pass Box? Its Role in Cleanroom Systems

A Pass Box is an essential tool in cleanroom environments, designed to safely transfer materials between areas of varying cleanliness levels while minimizing contamination risks. It acts as an airlock for objects, reducing unnecessary human movement and preventing contaminants from entering the controlled space.

Key Roles of a Pass Box in Cleanrooms

• Prevents cross-contamination: Controls airflow and limits direct contact between different cleanroom zones, reducing airborne particles and microbial exposure.
• Enhances operational efficiency: Allows seamless material transfer without disrupting cleanroom integrity.
• Maintains cleanroom standards: Ensures compliance with industry regulations such as GMP, ISO 14644, and FDA guidelines.

Types of Pass Boxes Available on the Market

1. Standard Pass Box (Static Pass Box)

A Static Pass Box is a simple design with interlocking doors, preventing both doors from opening simultaneously. It is primarily used to transfer materials between areas with similar cleanliness levels and does not have air filtration or sterilization features.

✅ Best for: Low-contamination-risk environments where basic containment is sufficient.

2. Dynamic Pass Box (Active Pass Box)

A Dynamic Pass Box is equipped with HEPA/ULPA filtration, maintaining controlled airflow to eliminate dust and contaminants before materials enter a cleanroom.

✅ Best for: Pharmaceuticals, biotechnology, and semiconductor industries that require strict air filtration when moving items from lower to higher cleanliness zones.

3. VHP Pass Box (Vaporized Hydrogen Peroxide Pass Box)

This advanced Pass Box integrates VHP sterilization technology to decontaminate objects before entering the cleanroom. The VHP cycle kills bacteria, viruses, and spores, making it ideal for industries requiring high sterilization levels.

✅ Best for: Pharmaceutical manufacturing, medical devices, and hospitals where sterility is critical.

4. Pass Box with UV Sterilization

This type of Pass Box uses UV-C light to disinfect item surfaces, effectively neutralizing bacteria, fungi, and viruses before transfer.

✅ Best for: Laboratories, food processing, and healthcare facilities needing an extra layer of sterilization.

Challenges in Item Transfer and Contamination Risks

1. Risk of Cross-Contamination

If items are not properly sanitized before transfer, contaminants like bacteria, dust, and microbes can enter the cleanroom, jeopardizing production quality. Surfaces like door handles and trays can also become contamination hotspots if not regularly disinfected.

2. Human Errors in Operation

Manual handling mistakes, such as simultaneous door opening, can disrupt airflow balance and allow contaminated air to enter the cleanroom. Inconsistent sanitization procedures and lack of proper training can further increase contamination risks.

3. Lack of Tracking and Monitoring

Traditional Pass Boxes rely on manual record-keeping, leading to inaccuracies and limited traceability of item transfers. Without real-time tracking, it becomes challenging to enforce cleanroom safety protocols effectively.

How to Overcome These Challenges?

AI-powered Pass Box solutions can revolutionize contamination control by integrating automated monitoring, AI-based recognition, and digital tracking, ensuring higher efficiency, safety, and regulatory compliance in cleanroom operations.
