pass box

PASS BOX UNIT The pass box is one of the important and essential equipment of the clean room, which is used to transfer the goods from outside the room to inside and vice versa. The use of the pass box reduces the number of times the main entrance door is opened and closed, and as a result, the particles entering the room are also reduced, which helps to maintain the cleanliness of the room. pass boxes are divided into active and inactive categories. The passive type includes two doors, a chamber and an interlock system, but the active type has an air shower, which has a motor, Hepa filter, pre-filter, and a nozzle. Before entering the room, it is cleaned and absorbed by the filters. Due to the existence of the interlock system in the pass boxes, when one door is opened, the other door is locked, which prevents a sudden drop in pressure in the clean room. Faraz Kavian company produces different dimensions of pass boxes with two types of full steel and semi-steel (inside steel).
