Dynamic Pass Boxes

Dynamic Pass box is generally used between clean area and non-clean area, also between clean rooms of a different class for transfer of materials. Personnel traffic is the most important factor which must be controlled. Dynamic Pass box is an effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement. The filter blower assembly is employed in the dynamic pass box to ensure that a positive pressure environment is maintained within the pass box so that cross-contamination does not occur from nonclean areas to clean areas.
