A “Dynamic Pass Box” is an apparatus used in controlled environments such as clean rooms. This type of pass box is designed to minimize particle and contamination levels in the environment during material transfer.

The term “Dynamic” indicates that the air and other conditions inside this box can vary during the transfer process. Dynamic Pass Boxes are employed in sensitive environments like microelectronics manufacturing, laboratory research, pharmaceutical production, where maintaining low contamination levels is crucial.

These boxes are specifically designed to minimize environmental contamination during material transfer and preserve the cleanliness of the working environment.
