YOUTH Pass Box / Pass-Through for Cleanroom

What is Pass-Box for Cleanroom?

A pass-box (or pass-through) for a cleanroom is a device that allows materials to be transferred into or out of the controlled environment without compromising its cleanliness. Cleanrooms are used in various industries, especially in pharmaceutical, biotech, and semiconductor manufacturing, where maintaining a contaminant-free environment is crucial.

Here’s how a pass-box works and its features:

Design: It’s essentially a box with doors on both sides. One door opens to the cleanroom, and the other opens to a non-cleanroom environment.

Interlock System: To prevent both doors from being opened simultaneously (which would compromise the cleanroom’s environment), most pass-boxes have an interlock system. This means when one door is open, the other remains locked.

Construction: They are typically made of stainless steel or other non-particle-shedding materials to ensure cleanliness.

UV Light: Some pass-boxes come equipped with ultraviolet (UV) lights to disinfect materials before they enter the cleanroom.

HEPA/ULPA Filters: To maintain cleanliness, some advanced pass-boxes have built-in HEPA (High-Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air) filters that clean the air inside the box.

Operation: When materials need to be transferred into the cleanroom, they are first placed in the pass-box from the outside. After closing the external door, the materials can be disinfected (if the box has a UV light). Once ready, the internal door can be opened from the cleanroom side to retrieve the materials.

Types: There are different types of pass-boxes, including static pass-boxes (which don’t have any air filtration) and dynamic pass-boxes (which have air filtration and sometimes maintain a positive pressure to prevent contaminants from entering).

Using a pass-box helps in reducing the traffic in and out of the cleanroom, which can introduce contaminants. It’s an essential tool for maintaining the integrity of a cleanroom environment.

What is the VHP Pass Box?

The VHP (Vaporized Hydrogen Peroxide) Pass Box is a pivotal device in the pharmaceutical industry for the transfer of items in a controlled environment. It is especially vital in places where there’s a necessity to prevent cross-contamination, such as in aseptic production areas and high-purity labs.

The application of “vhp in pharmaceutical” processes via the VHP Pass Box presents numerous advantages:

  1. Efficient Disinfection: Offering rapid and comprehensive disinfection utilizing VHP, ensuring minimal transfer delays.
  2. Reliability: The adoption of “vhp in pharmaceutical” procedures underscores the proven efficiency and safety of Vaporized Hydrogen Peroxide as a disinfectant, tailored specifically for stringent pharmaceutical standards.
  3. Space-saving Design: The VHP Pass Box’s compact nature facilitates installations even in spatially constrained environments.

The VHP Pass Box epitomizes the importance and effectiveness of “VHP in pharmaceutical industry” practices, safeguarding both product quality and safety throughout the production spectrum.

Static Pass Boxes

Static pass boxes are a viable choice for cleanrooms where the demand for contamination control is stringent. They are engineered to allow the transfer of materials without any airflow, making them a suitable fit for maintaining a steady cleanroom state.

Dynamic Pass Boxes

On the flip side, dynamic pass boxes incorporate a mechanism of airflow filtration. They are indispensable for transferring materials between controlled and uncontrolled environments, ensuring a continuous flow of filtered air to combat contamination.
