Definition of Pass Box

According to different self-locking interlocking methods, the Pass Box Clean Room can be divided into electronic device self-locking interlocking Pass Boxand mechanical equipment self-locking interlocking Pass Box. According to the role of purification treatment, Pass Box can be divided into general Pass Box and Air Shower Pass Box. The two sides of the Pass Box are equipped with special sealing strips on the inner side of the door to ensure the airtightness of the Pass Box. The Air Shower Pass Box is equipped with air shower nozzle at the top, centrifugal fan and high-efficiency air supply outlet, which has stronger purification effect.

Objects transfer: The Stainless Steel Pass Box is mainly used for the transfer of small objects between the clean area and the clean area, and between the clean area and the non-clean area. This can reduce the number of times the door of the  Clean Room is opened, thus reducing the risk of contamination of the clean area.

Airlock effect: The Stainless Steel Pass Box has the effect of an airlock, which can prevent the high pressure in the high-level Clean Room from being released. During the transfer of goods, the Pass Box can ensure that the air outside the Clean Room will not affect the cleanliness of the room.

Blowing effect: Some types of Pass Box, like the Air Shower Pass Box will blow out high-speed, clean airflow from the top to remove dust particles on the surface of the items when transferring items. This further ensures the cleanliness of the items entering the clean area.

The Role of Pass Box

Pass Box plays an important role in maintaining the Cleanroom environment, preventing cross contamination, and improving work efficiency. By choosing the right type of Pass Box and reasonable installation and use, it can further meet the needs of various industries for cleanliness. 

Maintaining the clean room environment: Strict control of entry and exit goods purification, as well as the use of high-efficiency filtration systems and regular cleaning and disinfection measures to prevent contamination, you can ensure that the cleanliness of the air inside the clean room, particle concentration and the number of microorganisms to meet the required standards.

Prevent cross contamination: The interlocking device of the Pass Box is usually equipped with electronic or mechanical interlocking device to ensure that when transferring items, one door can not be opened when the other door is opened, thus avoiding air convection and cross contamination between the clean room and non-clean room. And the sealing performance of the Pass Box, that the two sides of the Pass Box are equipped with special sealing strips on the inner side of the door to ensure the airtightness of the transfer window and further prevent the contaminated air from entering the clean room.

Improvement of work efficiency: Through two different ways of opening sliding open and compact structure design. The sliding opening method makes the sealing door slide open in the horizontal direction, which not only saves space, but also makes the operation easier and faster. Compact structure design through a reasonable structural design, so that the overall size of the Pass Box is more compact, so as to save space and improve the utilization of space. At the same time, the compact structure also helps to reduce the waste of time in the transfer process and improve work efficiency.
