Introduction to Pass-Thru Cabinets
AXENIC SYSTEMS (established in 1995) are certified manufactures and suppliers of Pass-Thru Cabinets in India with high-quality steel & suitable class HEPA filters and pre-filters to carry out the decontamination process in a cleanroom. Airborne particles on the material may affect the research of a company so we always recommend AXENIC Pass-Thru Cabinets to all our clients. We believe in innovative designs, quality & great after-sales support to all clients with spare parts availability.
Pass-Thru Cabinets is a closed steel box with dual door used for transferring the material from the nonsterile door to a sterile door inside the cleanroom. These boxes offer a controlled environment to the cleanroom from airborne cross-contamination for an enhanced research environment. These specified entry systems reduce the necessity for people to enter the cleanroom, and thanks to lower traffic inside the cleanroom, contamination is significantly reduced. As the name suggests itself, the main and only work of a pass box is to pass material from one side to other without raising contamination issues and if any particulate matter presents on the material surface, it swipes away during the process.
Types of Pass-Thru Cabinets
Pass-Thru Cabinets is a cleanroom equipment designed in two categories one is a dynamic pass box and the other is a static pass box.
DYNAMIC PASS BOX (DPB):
A dynamic pass box is installed between classified and non-classified areas. Material is passed through vertically HEPA filtered air. The equipment is designed in complete Stainless steel 304 with an interlocking system, Illumination light, UV light, Fan Motor, 0.3 microns HEPA filter. HEPA Filters are suction filters used to prevent any type of cross-contamination. The interlocking system will give the benefit of opening one door at a time during the pass-through of material. They are used to transfer materials from uncontrolled to controlled environments. Dynamic pass box functions like an airlock or laminar air flow unit.
STATIC PASS BOX:
Static pass box is mounted only between two clean room areas and has no air supply or extract. It is also recognized as a passive pass box and equipped with UV light. Static pass box is designed with an interlocking system, UV light, magnetic door locking & buzzer alarm; it has no HEPA filters and Fans for passing through the material. They are used to transfer materials between two rooms of equivalent cleanliness levels and are designed for nominal personnel movement.

Working principle of Pass-Thru Cabinets
Pass-Thru Cabinets are installed on the wall between the clean room and the other room. It is a four-sided compartment with two doors – one opens in the clean room and another opens in the other room. The electro-magnetic interlocking system permits opening of any one door at a time. This prevents the direct air flow between the clean room to the other room. This eliminates the need to open the door of the clean room frequently for transmitting the material. Pass box helps in accomplishing the material transfer without negotiating the level of hygiene in the clean room.
