1. Quick Overview of Cleanroom Pass Boxes for Medical Facilities

What is a Pass Box?

A Pass Box (also known as a cleanroom transfer hatch) is a specialized device installed between two cleanroom areas of different cleanliness classes. Its function is to transfer materials, tools, or samples without disrupting air pressure, cleanliness level, or contamination control between rooms.

In the medical sector — especially in pharmaceutical manufacturing, microbiology labs, or medical device production — Pass Boxes play a crucial role in ensuring a “clean - isolated - controlled” process in compliance with GMP standards.

Why are Pass Boxes mandatory in GMP-compliant medical cleanrooms?

According to GMP (Good Manufacturing Practices), the transfer of items between clean areas must:

  • Avoid turbulence or disruption of the clean airflow
  • Limit direct contact between personnel and items
  • Prevent cross-contamination or recontamination

Pass Boxes achieve this by:

  • Isolating both sides using a dual-door interlock system
  • Allowing integration of UV sterilization, HEPA filters, and pressure differential sensors to enhance hygiene
  • Reducing the frequency of personnel gowning and movement, which helps save time and operational costs

Note: During actual GMP audits, missing or improperly installed Pass Boxes may result in critical non-compliance findings.

2. Key Factors That Affect the Price of Medical Pass Boxes

Pass Box pricing varies depending on technical specifications, material selection, and integrated features. Below are the main cost-determining factors:

1. Type of Pass Box

Type

Description

Estimated Price (VND)

Manual Pass Box

Basic mechanical lock, manual door operation

8 - 12 million

Semi-automatic Pass Box

Electronic interlock system

13 - 18 million

Fully Electronic Pass Box

Automated control with sensors

18 - 25 million+

Pass Box with UV Light

Sterilization via UV lamp

+1 - 3 million (extra)

HEPA Filtered Pass Box

Includes H13-H14 grade clean air filtration

+3 - 5 million (extra)

Tip: For microbiology labs or high-risk pharmaceutical zones, it's recommended to choose models with both UV & HEPA systems for maximum safety.

2. Size and Material

Factor

Common Options

Impact on Cost

Size

500x500mm, 600x600mm, or custom dimensions

Larger units cost more

Material

Inox 304 (standard), Inox 316L (premium)

316L is 10-20% more expensive

Powder-coated Steel

Lower-cost alternative, rarely used in medical

Only suitable for storage zones

In medical cleanrooms, Inox 304 is the minimum standard. Inox 316L is preferred in pharmaceutical applications due to its superior corrosion resistance and microbial safety.

3. Optional Features & Upgrades

Add-on Feature

Purpose

Additional Cost

Automatic Door Sensor

Enhanced convenience and operation safety

+2 - 4 million VND

Pressure Differential Display

Monitor room pressure levels

+1.5 - 2.5 million VND

HEPA Filter + Fan Module

Internal recirculating clean air system

+4 - 6 million VND

Smart Interlock Control

Programmable door locking/unlocking logic

+3 - 5 million VND

Recommendation: Choose add-ons based on the actual location and cleanroom function — avoid unnecessary features to optimize investment cost.

3. Recommendations for Choosing Pass Boxes in Medical Cleanrooms

Each area within a medical cleanroom system has specific technical requirements and contamination control levels. Choosing the right Pass Box not only ensures compliance with GMP standards but also helps optimize investment and operational costs.

Here are tailored recommendations for common cleanroom areas in medical facilities:

Weighing Room - Prioritize Absolute Safety

  • Recommended Type: Electronic Pass Box with Interlock
  • Optional Add-ons: Door sensors, differential pressure display, UV sterilization
  • Reason:
    • Highly sensitive zone with potential active ingredient dust
    • Requires strict control over door opening to prevent airflow mix
    • Electronic Pass Boxes support procedural consistency and reduce human error

Pro tip: Choose models with an LED status display and door open timer for better monitoring.

Packaging Area - Balance Cost & Efficiency

  • Recommended Type: Semi-automatic Pass Box with UV light
  • Reason:
    • Ensures materials are sterilized before entering critical zones
    • Lower cost compared to fully electronic models
    • Meets microbiological control requirements under GMP

Suggested Upgrade: Add a UV timer or auto sensor activation for improved user convenience.

Storage Area - Cost-Effective, Still Compliant

  • Recommended Type: Manual or basic semi-automatic Pass Box
  • Reason:
    • Lower frequency of use; minimal sterilization needed
    • Still requires separation of material flow from other areas
    • Ideal for secondary pharmaceutical storage zones with limited budgets

Reminder: Always use dual mechanical locks to prevent simultaneous door opening.

Note: Pass Box configuration can be adjusted based on cleanroom layout and investment budget — as long as the system complies with the one-way flow, isolation, and cross-contamination control principles of medical-grade cleanrooms.
