The ‌Air Shower Pass Box‌ is a key piece of equipment in cleanrooms, combining the functions of an air shower and a pass box. It is primarily used for transferring small items between clean and non-clean areas, minimizing door openings and controlling contamination. Below are its main features and applications:

‌Core Functions & Structure‌

1. ‌Purification Mechanism‌

   • Removes particles from surfaces using ‌high-efficiency filters (99.99% particle retention)‌ and ‌stainless steel nozzles with ≥20 m/s airflow‌.
   • Features a ‌two-stage filtration system (pre-filter + HEPA filter)‌ with ‌EVA sealing‌ for airtightness.

2. ‌Interlock System‌

   • ‌Mechanical or electronic interlock‌ ensures both doors cannot open simultaneously, preventing cross-contamination. Electronic interlocks use ‌electromagnetic locks and indicator lights‌ for precise control.

3. ‌Material & Configuration‌

   • ‌Exterior‌: Cold-rolled steel powder-coated or stainless steel.
   • ‌Interior‌: Stainless steel workbench or unpowered rollers.
   • ‌Optional accessories‌: UV sterilization lamps, tempered glass windows, infrared sensor air showers, etc.

‌Applications‌

• ‌Industries‌: Biotech labs, pharmaceutical plants, food processing, electronics manufacturing, and other high-cleanliness environments.
• ‌Transfer Process‌: Follows the ‌"one door open at a time"‌ rule—close the outer door before opening the inner door to prevent airflow contamination.

‌Specifications & Customization‌

• ‌Standard Sizes‌: Common internal dimensions: 600×600×600 mm, with custom sizes available.
• ‌Price Range‌: Varies by configuration, typically from ‌$100to$1,000+‌ (e.g., 304 stainless steel models start at ~$130).
