A three-way door pass box is a specialized piece of equipment used to transfer materials between three separate environments while maintaining cleanliness and preventing contamination. It is commonly used in cleanrooms, laboratories, and other controlled environments where maintaining a sterile environment is crucial.
Construction and Operation
A three-way door pass box typically consists of a chamber with three interlocked doors, one on each side. Each door is connected to a separate environment, and the doors are designed to prevent air from flowing from one environment to another. This helps to prevent the spread of contaminants.
The pass box may also have a HEPA filter to clean the air inside the chamber before it is released into the cleanroom. This further reduces the risk of contamination.
