Introduce:

Pass boxes are used to transfer material for blending, granulation or sterilization in manufacturing area and sterilization and

incubation in microbiology laboratory.

In some cases equipment parts are also transferred through the pass boxed in sterile manufacturing areas.

Pass boxes help to prevent the air flow from one area to another while transferring the material.

One door of the pass box opens at time and both the doors cannot be opened simultaneously.

There should be an interlocking system int he pass boxes.

Pass boxed are two types:

A. Dynamic pass box

Dynamic pass box works like an air lock or laminar air flow unit. Clean air enters in the pass box and prevents the entrance of the contamination. Dynamic pass boxes may be

B. Static pass box

Static pass boxes are simple boxes mounted between two areas and also known as passive pass boxes.

Area having higher cleanliness level shall have higher pressure that helps to prevent the entrance of contamination in the sterile area.

Ultra-violet light is also installed in the pass boxes to remove the contamination that may enter during the transfer of material. It should be replaced after 1000 burning hours.

Pass boxes should be cleaned with disinfectants at regular intervals.

Efficiency of the pass boxes should be verified by validation. Validation may be done by exposing the known population of the bacterial culture.

Paramter :

Customer’s design is available.

Pass box as an auxiliary device of a clean room, mainly used to deliver small objects between clean area and clean area , unclean area and clean area . In order to reduce doors opening times of clean room, to mixmum reduce the pollution of the clean area.

Clean room air shower pass box:

Air shower pass box is high efficiency filter and fan built-in in normal pass box.
It is suitable for cargo transfer from clean areas to unclean areas or from low clean areas to high clean areas.

Application

It mainly applied to the goods transimission between the clean and non-clean areas, preventing the outside dust particles from coming into the clean area due to air circulation.
The possible pollution to clean room can be minimized, so the cleanliness of the clean room can be maintained.

Factory test include:

-- functional test and visual inspection
-- electrical safety tests
-- air velocity testing
-- purification rank test (if need)
