‌Cleanroom Pass-Through Windows‌

Pass-through windows used in cleanrooms are specialized equipment designed to transfer items between areas of different cleanliness levels while maintaining contamination control. Their core functions and features include:

‌I. Definition and Purpose‌

Pass-through windows physically isolate and purify items during transfer between cleanrooms and external environments (or zones with varying cleanliness levels). They minimize door openings and block direct air exchange, preventing contaminants like dust and microbes from entering high-cleanliness zones‌

‌II. Structural Design and Features‌

1. ‌Materials and Sealing‌

   • ‌Housing‌: Stainless steel or aluminum alloy for corrosion resistance and easy cleaning‌
   • ‌Seals‌: High-elasticity silicone/fluororubber gaskets ensure airtight closure‌

2. ‌Interlock and Purification Systems‌

   • ‌Dual-door design‌: Equipped with electronic/mechanical interlocks to prevent simultaneous opening of both doors‌
   • ‌HEPA filters and UV lamps‌: Remove airborne particles and sterilize microorganisms‌
   • ‌Laminar airflow‌: Optional unidirectional airflow systems (e.g., top-down airflow) for ISO Class 5 cleanliness‌

‌III. Types and Applications‌

‌IV. Key Industries‌

Pass-through windows are critical in industries requiring stringent contamination control:

• ‌Electronics‌: Semiconductor and microchip manufacturing;
• ‌Biopharma‌: Sterile drug production and labs;
• ‌Food Processing‌: Aseptic packaging;
• ‌Optics‌: Precision lens and display manufacturing‌

‌V. Usage Guidelines‌

1. ‌Operation‌: Follow strict door alternation protocols to avoid cross-contamination‌
2. ‌Maintenance‌: Regularly replace HEPA filters, clean UV lamps, and sanitize interiors‌
3. ‌Selection Criteria‌: Choose based on cleanliness level, sterilization needs, and item type‌
