Dynamic Pass Box

Cleanroom environments are critical in industries that involve hazardous materials, and contamination control is a top priority. These enclosed spaces are equipped with technology that effectively reduces the presence of airborne particles and other contaminants. Nevertheless, the movement of materials in and out of cleanrooms poses a significant threat to the environment’s integrity. In such cases, a dynamic pass box plays a pivotal role in mitigating contamination risk.

A cleanroom dynamic pass box is a specialized piece of equipment that creates a controlled environment in cleanrooms and other controlled settings, effectively reducing the possibility of contamination and maintaining high cleanliness standards. The pass box is a compact, enclosed space located between the cleanroom and surrounding areas like storage rooms or equipment areas. The double doors equipped in the pass box are interlocked, ensuring that the cleanroom is not exposed to the outside environment when items are being transferred. This setup helps to keep the environment within the cleanroom stable and free from contaminants.

The dynamic pass box uses advanced technology like fans and filters to ensure there is a significant barrier between the cleanroom and the surrounding environment. The fans within the pass box create a flow of air, while filters remove contaminants before the air enters the cleanroom. The primary objective of this setup is to maintain the airflow and air pressure within the cleanroom while preventing contamination, ensuring that the environment remains spotless.

Industries dealing with hazardous materials must maintain cleanroom standards, and a dynamic pass box is a must-have to mitigate contamination risks when transferring materials. It’s an investment that pays off in the long run as it ensures a clean and healthy environment.

What is a Dynamic Pass Box?

A dynamic pass box is a specialized piece of equipment used in cleanroom technology. It is a sealed chamber with two or more doors, used to transfer materials from a non-cleanroom environment to a cleanroom or vice versa, while maintaining the cleanliness of the cleanroom environment. The box is equipped with HEPA filters to ensure the air passing through it is free from contaminants.

How Does a Dynamic Pass Box Work?

Dynamic pass boxes work on a simple principle of air filtration. The HEPA filters in the box capture and remove particles as small as 0.3 microns, ensuring that the air passing through it is clean. The box is equipped with interlocked doors that prevent both doors from being open at the same time, thus maintaining the pressure differential between the cleanroom and non-cleanroom environments. Materials are placed in the box and transferred from one side to the other without the need to open the cleanroom door.

Benefits of Using Dynamic Pass Boxes

Using a dynamic pass box offers several benefits, including:

  • Prevents the entry of contaminants into the cleanroom environment
  • Maintains the pressure differential between the cleanroom and non-cleanroom environments
  • Reduces the risk of cross-contamination
  • Provides a controlled environment for material transfer
  • Saves time and labor by eliminating the need to gown up and down to enter the cleanroom
  • Improves overall efficiency and productivity

How to Choose the Right Dynamic Pass Box?

Choosing the right dynamic pass box depends on several factors, including:

  • The level of cleanliness required in the cleanroom
  • The size and weight of the materials being transferred
  • The frequency and volume of material transfer
  • The available space for the pass box
  • The required features, such as interlocked doors, UV sterilization, and automated material transfer systems.

Maintenance and Cleaning of Dynamic Pass Boxes.

Proper maintenance and cleaning of dynamic pass boxes are essential to ensure their optimal performance and longevity. Regular cleaning and disinfection of the box and its components, such as filters and doors, should be done using approved cleaning agents. Routine maintenance, such as filter replacement and calibration of pressure gauges, should also be done according to the manufacturer’s recommendations.

Common Applications of Dynamic Pass Boxes

Dynamic pass boxes find applications in various industries that require contamination control, including:

  • Pharmaceuticals
  • Biotechnology
  • Semiconductor manufacturing
  • Medical device manufacturing
  • Food and beverage processing

Future Developments in Dynamic Pass Boxes

As technology advances, so does the development of dynamic pass boxes. Some of the future developments expected in dynamic pass boxes include:

  • Improved automation for material transfer
  • Integration with monitoring systems for real-time data analysis
  • Enhanced sterilization capabilities, such as plasma sterilization and ozone sterilization
  • Development of dynamic pass boxes for hazardous materials, such as radioactive materials

How many types of cleanroom dynamic pass-box?

There are two main types of dynamic pass boxes: single-door dynamic pass boxes and double-door dynamic pass boxes. Single-door dynamic pass boxes have one door on either side of the box, while double-door dynamic pass boxes have two doors on either side of the box. Both types of dynamic pass boxes offer a controlled environment for material transfer and prevent the entry of contaminants, but double-door dynamic pass boxes are generally considered more effective in reducing the risk of cross-contamination as they prevent the simultaneous opening of doors on both sides of the box.
