Dynamic pass box is normally used to transfer materials and goods between cleanrooms of diferent levels or between cleanroomand non-cleanroom. Besides UV light and an interlock system, dynamic pass box is equipped with a suction HEPA filter of around 0.3 microns.The dynamicpass box also has a differential pressure gauge ranging from 0 to 250 pa. lt is also equipped with a motor blower for blowing out dustparticles.
Dynamic pass box working principle
Dynamic pass box is a self-cleaning pass box. The air is sucked by a centrifugal fan then passed through HEPA fiter. After the pressureis equalized, the filtered air enters the working zone at a uniform air velocity, forming a clean working environment.The air outlet surface can also be replaced with a nozzle, which increases the air velocity to meet the requirements of blowing dust onthe material surface
