Cleanroom Air Purification Different Types Of Stainless Steel Pass Box Air Shower

Air Shower vs. Pass Box: Key Differences

Air showers and pass boxes are two essential auxiliary devices in cleanrooms, differing significantly in function, purpose, and operation.

Primary Function

  • Air Shower‌: Primarily used to blow and purify personnel or materials entering the clean area, removing dust and other contaminants from their surfaces.
  • Pass Box‌: Designed for transferring items between different cleanliness levels or controlled zones, with the key goal of preventing cross-contamination during the transfer process.

Purpose

  • Air Shower‌: Focuses on decontaminating the ‌surface‌ of people or objects to ensure they are clean before entering the clean area.
  • Pass Box‌: Ensures ‌safe material transfer‌ between zones without compromising the cleanliness of either area (unless it is a pass box with an integrated air shower).

Working Principle

  • Air Shower‌: Uses high-speed, filtered air jets (often exceeding 20 m/s) from multiple directions to dislodge and remove particles from personnel or goods.
  • Pass Box‌: Typically employs an ‌interlocking system‌ (mechanical or electronic) to prevent both doors from opening simultaneously, thus avoiding direct airflow between zones. Some advanced pass boxes (e.g., air shower pass boxes) also include internal fans and HEPA filters for additional decontamination.

Summary

In short, an ‌air shower is a "decontamination unit"‌, while a ‌pass box is a "transfer channel"‌. Air showers deeply clean people and items before they enter the cleanroom, whereas pass boxes facilitate safe material transfer between zones, minimizing door openings and cross-contamination risks.
