Systematic Design Plan for Adding Air Shower Rooms and Pass-Through Windows to Cleanrooms

To optimize contamination control in cleanrooms, integrating air shower rooms (for personnel decontamination) and pass-through windows (for material transfer) requires adherence to core design principles that ensure separation of personnel/material flows, minimize cross-contamination, and maintain cleanliness classes. Key considerations center on modularity, aerodynamics, and smart control integration.

I. Air Shower Room Design Essentials

1. ‌Location & Layout‌:

   • Positioned at personnel entry points (e.g., between gowning rooms and core clean zones) as an airlock buffer to prevent external contamination.
   • Slim-profile design (standard: 1200×1000×2180 mm), with size customized based on cleanroom traffic (e.g., 2–4-person capacity for 20–40-worker facilities).

2. ‌Aerodynamic Configuration‌:

   • Airflow velocity ≥20 m/s, equipped with HEPA filters (H13 grade, 99.99% efficiency @0.3μm) and pre-filters (G4 grade) for rapid removal of particles/microorganisms.
   • Dual-door electronic interlock system to prevent simultaneous opening and maintain positive pressure gradients.

3. ‌Materials & Functions‌:

   • Shell: Powder-coated cold-rolled steel or stainless steel (201/304); interior: satin-finished stainless steel for corrosion resistance and easy cleaning.
   • Optional IoT remote monitoring, temperature/humidity control, reducing energy consumption by 20–30%.

II. Pass-Through Window Design Essentials

1. ‌Location & Dimensional Optimization‌:

   • Installed at main traffic junctions (e.g., clean/non-clean zone boundaries) with temporary staging space for efficient material transfer.
   • Size selection by payload: standard windows (500×500 mm) for lightweight items; custom floor-level tunnels for heavy materials (e.g., raw ingredients).

2. ‌Structural Innovations‌:

   • Sliding-door mechanism (replaces swing doors) to minimize operational space.
   • Stainless steel/glass sealed enclosures (joint leakage ≤0.01%), with R50mm curved corners in Class 100 zones to prevent dust buildup.

3. ‌Contamination Control‌:

   • Dual-door mechanical/electronic interlocks + UV sterilization lamps to block cross-contamination.
   • Air shower-type windows integrate HEPA filters (≥20 m/s airflow) and negative pressure for bio-clean zones.

III. Integration & Implementation Standards

1. ‌Personnel/Material Flow Separation‌:

   • Personnel path: Gowning → Handwashing → Buffer room → Air shower → Clean zone.
   • Material path: External corridor → Pass-through disinfection → Buffer corridor → Core zone.
   • Maintain 10–15Pa pressure gradients (highest in core zones) via smart dampers.

2. ‌Installation & Validation‌:

   • Modular prefabricated components (factory-built in clean environments), on-site installation within 48 hours for 500 m².
   • Validation testing: Smoke tests to confirm ≤0.1% dead zones; 72-hour continuous airborne particle monitoring (e.g., ≤1 cfu/m³ in ISO Class 5 zones).

Critical Considerations

• ‌Industry Adaptations‌:
  • Biopharma: Prioritize air shower-type pass-throughs + negative pressure isolation.
  • Electronics: Implement anti-static designs.
• ‌Cost Efficiency‌: Modular solutions enable 98% material reuse, reducing relocation retrofit time by 40%.
