A Dynamic Pass Box is an active contamination control device used to transfer materials from an uncontrolled (less clean) environment into a controlled (clean) environment (e.g., from a corridor into a cleanroom). It uses HEPA-filtered airflow to prevent contaminants from entering the controlled space.

Key Features & Mechanism HEPA-Filtered Airflow System

Provides unidirectional or turbulent airflow to flush out particles during transfer.

Maintains positive pressure inside the pass box to prevent ingress of contaminants.

Interlocked Doors (Mechanical or Electromagnetic)

Ensures only one door can be opened at a time, preventing cross-contamination.

Some models include alarms or LED indicators to alert if both doors are accidentally opened.

Designed for Uncontrolled-to-Controlled Transfers

Used when moving materials from a non-classified (or lower-class) area into a cleanroom (e.g., ISO Class 8 to ISO Class 5).

Optional UV-C Disinfection

Some advanced models include UV sterilization to decontaminate surfaces before transfer.

A Static Pass Box is a contamination-controlled transfer chamber designed for safe material movement between two equally classified clean environments (e.g., ISO Class 5 to ISO Class 5). It eliminates the need for personnel entry/exit, minimizing cross-contamination risks while maintaining zone integrity.

Key Features & Technical Specifications1. Contamination Control Design

• Zero Airflow System: Unlike dynamic pass boxes, relies on physical barriers (not HEPA airflow) for isolation.

• Interlocked Doors: Electromagnetic or mechanical interlocks prevent simultaneous opening (audible/visual alarms optional).

• Smooth Surfaces: Stainless steel 304/316 or powder-coated finishes for easy decontamination.

2. Compliance & Applications

✔ Cleanroom-to-Cleanroom Transfers: Pharma, biotech, electronics (equal ISO/GMP classifications).
✔ Material Types: Tools, packaged samples, small equipment (no personnel passage).
✖ Prohibited Use: Transfers from uncontrolled to controlled environments (requires dynamic pass box).

3. Optional Enhancements

• UV-C germicidal lamps (surface decontamination).

• Particle monitoring ports (for validation).

• CIP (Clean-in-Place) compatibility.
