If you’re setting up a cleanroom or upgrading your contamination control systems, you’ve probably run into this question: Should I go with a static or dynamic pass box? The answer depends on your specific application.
Static Pass Boxes
❄️ No ventilation system
🛠️ Simple design, easy to install
🔒 Best for use between areas of the same cleanroom classification
💡 Used for tools, documents, and non-sensitive materials
When to Use: In pharmaceutical warehouses, microbiology labs, or cleanrooms where materials are not highly sensitive to airborne particles.
Dynamic Pass Boxes
💨 Equipped with a motor/blower and HEPA/ULPA filters
🌪️ Air purging removes contaminants before transfer
🚨 Used between areas of different classification levels
🔬 Ideal for sterile pharmaceutical production, electronics manufacturing, and biotech
When to Use: When transferring items from an uncontrolled or lower-grade area into a Class 100 (ISO 5) cleanroom.
Bottom Line
Choosing between static and dynamic pass boxes isn’t just a budget call — it’s a safety and compliance decision. If you’re handling sensitive or sterile items, dynamic is the way to go. For general-use or material staging, static might be sufficient.
