Static Pass Box for Cleanroom Material Transfer and Contamination Control
GMP-Grade Static Pass Box for Controlled Cleanroom Transfer
When materials need to be transferred between two cleanroom areas with the same classification avoiding pressure loss during transit, a Static Pass Box offers the perfect solution. Designed without airflow or filtration, this pass box provides a physical barrier against contamination, using electromagnetic interlocks and optional UV sterilization to maintain hygiene.
Dyna’s Static Pass Boxes are built using cleanroom-grade stainless steel, with smooth interiors, toughened glass windows, and flush-mounting capability. They’re widely used in pharmaceutical production, microbiology labs, food packaging, and electronics assembly, where material movement needs to happen quickly and cleanly.

What is a Static Pass Box?
Static Pass Boxes are widely used in pharmaceutical manufacturing facilities, biotechnology laboratories, healthcare cleanrooms, medical device production plants, research centres, and other contamination-sensitive environments. By creating a dedicated material transfer point, the system helps reduce unnecessary personnel traffic and supports contamination control programmes.
How Does a Static Pass Box Work?
Step 1
Material is placed inside the pass box from one side.
Step 2
The first door is closed.
Step 3
The interlocking system prevents both doors from opening simultaneously.
Step 4
The receiving side opens the opposite door.
Step 5
Material is removed without direct personnel movement between rooms.
Why Are Static Pass Boxes Important in Cleanrooms?
Personnel movement remains one of the largest sources of contamination within controlled environments. Every door opening, operator movement, and material transfer increases the risk of introducing particles into critical areas.
Static Pass Boxes help reduce this risk by creating a controlled transfer point between adjacent rooms. Instead of personnel carrying materials through multiple cleanroom zones, items can be safely transferred through the pass box while maintaining cleanroom discipline and contamination control procedures.
The result is improved workflow efficiency, reduced contamination risk, and better cleanroom performance.
Static Pass Box vs Dynamic Pass Box
Many facilities evaluate both solutions before selecting a pass box system.
| Feature | Static Pass Box | Dynamic Pass Box |
|---|---|---|
| Air Filtration | No | HEPA Filtered |
| Internal Airflow | No | Yes |
| Suitable for General Material Transfer | Yes | Yes |
| Suitable for Sterile Areas | Limited | Preferred |
| Maintenance Requirement | Low | Moderate |
| Installation Cost | Lower | Higher |
Static Pass Boxes are typically used between areas of similar cleanliness classifications. Dynamic Pass Boxes are preferred where additional contamination control through HEPA-filtered airflow is required.
Common Materials Transferred Through Static Pass Boxes
Commonly transferred items include:
Raw materials
Packaging materials
Production components
Laboratory samples
Documentation
Measuring instruments
Medical consumables
Finished products
The use of dedicated transfer systems helps improve operational efficiency while reducing contamination risks.
Where Should a Static Pass Box Be Installed?
Typical installation points include:
Between cleanroom and preparation room
Between production and packaging areas
Between warehouse staging areas and controlled environments
Between laboratories and sample preparation rooms
Between gowning areas and manufacturing zones
Correct placement supports smooth material flow and helps maintain cleanroom zoning strategies.
Common Mistakes When Selecting a Static Pass Box
Common mistakes include:
Choosing Incorrect Dimensions
The transfer chamber should accommodate actual material sizes.
Ignoring Door Interlocking
Interlocking is critical to prevent simultaneous door opening.
Poor Installation Location
Placement affects workflow efficiency.
Overlooking Cleaning Requirements
Pass boxes should be easy to sanitise and maintain.
Ignoring Future Expansion
Material transfer requirements often increase as production grows.
Proper planning helps avoid costly modifications later.
Benefits of Static Pass Boxes
Creates a dedicated transfer barrier between controlled environments.
Improved Cleanroom Integrity
Reduces personnel movement between rooms.
Better Material Flow
Supports efficient transfer of materials and components.
Lower Maintenance Requirements
Simple design with minimal moving parts.
Support for GMP Compliance
Helps maintain contamination control procedures in regulated environments.
Static Pass Boxes in Pharmaceutical Manufacturing
Static Pass Boxes help support GMP-compliant workflows by reducing unnecessary movement between cleanroom zones and providing controlled transfer of raw materials, packaging materials, laboratory samples, and production components.
They are commonly used in:
Oral solid dosage facilities
Sterile manufacturing areas
Biotechnology facilities
API manufacturing plants
Quality control laboratories
Their role is often underestimated, but they are an essential component of cleanroom contamination control infrastructure.

Frequently Asked Questions (FAQs)
What is a Static Pass Box used for?
It allows the transfer of materials between cleanrooms of equal classification, without active airflow.
Does it require HEPA filters or fans?
No. Static pass boxes do not use internal airflow, making them simpler and more economical.
Should I install UV sterilization in it?
It’s recommended if biological or sterile materials are being passed.
Can I get a floor-standing model instead of wall-mounted?
Yes. Dyna offers both wall-integrated and standalone models based on your layout.
Need an economical and compliant solution for safe cleanroom-to-cleanroom material transfer?
Choose Dyna’s Static Pass Boxes for simplicity,
hygiene, and cleanroom integrity.
