NEED OF DYNAMIC & STATIC PASS BOX :
Static pass box are normally used to transfer a particular material between two areas generally of different cleanliness levels. The boxes can be said to transfer the materials from a high level of cleanliness to a lower level of cleanliness or vice versa. The static pass box while transferring the material, help to prevent air from flowing from one area to another. Pass boxes are made of stainless steel which is powder-coated
This Static pass box, & dynamic pass box also known as cleanroom pass box are very important so as to control air enviornment which is used to pass materials from controlled region to non controlled region and to transfer materials in clean enviornment. As, cleanrooms are being more pricesly required for any pharmecutical operations or laboratories tests, which helps in effective and controlled working.
