Modular Assembled Clean Room Pass Box SUS304 Interlock

Cleanroom Pass-Through Window‌

The cleanroom pass-through window is a critical auxiliary equipment for material transfer within cleanrooms, primarily used for transferring small items between clean zones or between clean and non-clean zones, minimizing door-opening contamination. Its key features and classifications are as follows:

I. Core Functions & Structure

1. ‌Contamination Isolation‌

   • Mechanical or electronic dual-door interlock design ensures doors on both sides cannot open simultaneously, effectively preventing cross-contamination.
   • Some models feature UV sterilization lamps or HEPA filters to enhance disinfection and purification.
   • Diagram: Pass-through window operation showcasing door interlock mechanism and UV disinfection.

2. ‌Material & Construction‌

   • Typically constructed with brushed 304 stainless steel panels for corrosion resistance and easy cleaning.
   • Equipped with High-Efficiency Particulate Air (HEPA) filters (efficiency ≥99.99%) and blowers to form a self-purification circulatory system.
   • Detail: 304 Stainless Steel material, HEPA filter location, and internal airflow circulation diagram.

II. Main Types & Application Scenarios

III. Operating Procedures & Maintenance Key Points

1. ‌Operating Procedure‌

   • Place item inside → Close external door → Activate UV disinfection or self-purification cycle → Internal personnel retrieves item.
   • ‌DO NOT open both doors simultaneously.‌ Item surfaces must be cleaned before transfer.

2. ‌Routine Maintenance‌

   • Clean inner walls & seals weekly; Check interlock sensitivity monthly.
   • Replace HEPA filters every 1-2 years; Replace UV lamps promptly upon end of lifespan.
   • Comparison Chart: Key specs of mainstream models (e.g., Suzhou Jienuo Self-Purifying, Shenzhen Huakong Lift-Door Type, Shandong Kaixuan UV Sterilization Model).

IV. Industry Application Cases

• ‌Pharmaceutical:‌ Activates dual sterilization (UV + Ozone) when transferring raw materials.
• ‌Electronics Workshop:‌ Laminar flow pass-throughs prevent static-attracted particle contamination of sensitive components.
• ‌Hospital Operating Room:‌ Mechanical interlock pass-throughs enable emergency instrument transfer while maintaining sterile conditions.
• Visuals: Electronics laminar flow pass-through workflow; Pharmaceutical sterilization pass-through live operation.
