Classification of Pass throughs/pass boxes
Passthroughs can be classified based on several factors:
- Size: Passthroughs can be in various sizes to accommodate different items or equipment.
- Material: They are made from materials such as stainless steel 201/304 or power coated plate for durability and cleanliness.
- Design: Passthroughs may feature single or double-door, and some may include interlocking systems for security during transfer.
However,Passthroughs also can be classified based on various criteria including their operation modes (static or dynamic) and the technologies such as Good Manufacturing Practice (GMP) compliance , the air flow and Vaporized Hydrogen Peroxide (VHP) sterilization.
The following main classifications for pass throughs:
Static & Dynamic:
Static Passthroughs: These are basic passthroughs designed for one-way transfer of materials or equipment between cleanroom areas. They typically feature manual doors and are suitable for low to medium traffic environments.
Dynamic Passthroughs: Dynamic passthroughs incorporate advanced features such as automated doors, air showers, and interlocking systems. They facilitate bi-directional transfer and are ideal for high traffic areas where maintaining cleanliness and minimizing contamination risk is critical.
GMP Compliance:
Some passthroughs are designed to comply with Good Manufacturing Practice (GMP) guidelines, which are regulations ensuring the quality, safety, and efficacy of pharmaceutical products. GMP-compliant passthroughs adhere to strict standards regarding design, construction, and operation, helping pharmaceutical manufacturers maintain compliance with regulatory requirements.
Airflow Characteristics:
Laminar Flow Passthroughs: LAF passthroughs are undirected airflow, which ensures that particles and contaminants are carried away from the transfer area in a controlled manner. Commonly used in environments requiring high cleanliness levels, such as semiconductor manufacturing&GMP manufacturing.
VHP Sterilization:
Passthroughs are with Vaporized Hydrogen Peroxide (VHP) sterilization technology ,It offers an additional layer of contamination control. VHP is an effective method for sterilizing surfaces and equipment in cleanroom. It can ensure that transferred items are thoroughly sterilized before entering or exiting the cleanroom, minimizing the risk of contamination.
We can tailor passthroughs to meet the specific requirements of different cleanroom environments & applications, If you have any inquiry or help pls contact us freely .
