Description
Static and Dynamic Pass Boxes are essential components in cleanroom environments, facilitating the transfer of materials between areas of varying cleanliness levels while minimizing contamination risks.
Static Pass Boxes:
Designed for transferring materials between cleanrooms of similar cleanliness levels, static pass boxes feature a simple design with interlocking doors to prevent simultaneous opening. They are equipped with ultraviolet (UV) light for sterilization and are commonly used for non-sensitive items.
Dynamic Pass Boxes:
Ideal for transferring materials between cleanrooms of different cleanliness levels or between clean and non-clean areas, dynamic pass boxes incorporate advanced features such as built-in HEPA or ULPA filters, UV light, and motorized blowers. These features enhance environmental control by removing particles and microorganisms from materials during transfer, making them suitable for sensitive pharmaceutical products.
Key Features:
Interlocking Doors: Both static and dynamic pass boxes are equipped with interlocking mechanisms to ensure that only one door opens at a time, preventing cross-contamination.
UV Sterilization: UV light is used in both types to sterilize materials before they enter the cleanroom, reducing the risk of contamination.
Filtration Systems: Dynamic pass boxes include HEPA or ULPA filters to remove airborne particles, enhancing the cleanliness of materials being transferred.
Blower Systems: Some dynamic pass boxes are equipped with motorized blowers to remove dust particles from the surfaces of materials, further reducing contamination risks.
Applications:
Pharmaceutical Manufacturing: Ensuring the integrity of sensitive materials during transfer between different cleanroom areas.
Laboratories: Maintaining contamination control when moving materials between controlled environments.
Medical Facilities: Protecting sterile areas from potential contaminants during material transfer.
Selecting the appropriate pass box—static or dynamic—depends on the specific requirements of the cleanroom environment and the sensitivity of the materials being transferred.
