DESCRIPTIONS:–

• Pass box is one of the clean room systems, which is used to transfer materials from one side to other side through controlled environment in order to avoid airborne cross contamination. As the name states itself, the primary and only work of a pass boxis to pass material from one side to other without raising contamination concern and if any particulate matter presents on the material surface, it swipes away during the operation. Interlocking door mechanism is the prime feature of a pass box, when door at one side is open the door at other side remains closed. It is popular with other names such as clean room pass through, clean transfer window and transfer hatch; in addition, it is widely used in microbiology laboratories in food, pharmaceutical and chemical industries.

A pass box is designed in two different types; static and dynamic, it is the user specific requirement which  decides the right design configuration. The difference between these two is explained as:

• Dynamic Pass Box equipment are made of powder coated high grades stainless steel (304 / 316 / 316 L) with international quality standard components including mechanically or electrically interlocked doors and UV light. These dynamic pass box equipment are equipped with suction filter made of stainless steel with 95% down to 5µ efficiency (EU-4rating) and supply filter made of aluminium with 99.999% down to 0.001 µ (EU-14 Rating.) An interlock guard system controls the inlet and the outlet of PASS BOX not be opened at the same time, in order to prevent the cross contamination.
