In some production processes and certain work environments, hygiene care is even more important. Products and even people, who through their own skin or clothing, for example, can contaminate the air. Therefore, equipment like antechambers and Pass Through are required in some companies.
These devices prevent particles from external sources from coming into contact with controlled environments when opening doors and windows.
This avoids problems such as cross-contamination, which can transfer microorganisms to food and cause disease.
For this reason, moreover, the food industry must use Clean Rooms in its production process, as the control of humidity, temperature and pressure also avoids contamination of the environment.
Naturally, for this, the rooms must be isolated, completely isolated from the other facilities.
The place is thus prepared for handling products and preserving their conditions, such as texture, color and consistency, without any type of contamination in the production process.
This security is essential in the manufacture of various products, such as food, medicines and packaging, as it allows the consumer to purchase with a guarantee of safety and quality.
In fact, there are many rules that deal with what must be done to ensure hygiene in production processes.
In the case of manufacturing drugs, for example, resolution RDC 17/2010 defines that the entry of personnel and materials must be done through antechambers and that there must be a system that prevents two doors from opening simultaneously.
Pass Through equipment ensures this process with systems and dimensions that can suit different industries. This article explains what they are, which models are available on the market and why they are so relevant for environments such as Clean Rooms.

What is Pass through?
Pass through can be translated as 'to cross', but in the industrial context, the term refers to a piece of equipment that is also known as a Passage Box.
The equipment is used to transfer materials between environments, such as from an external room to a Clean Room, and consists of a metal cabinet with excellent sealing.
Its finish can be aluminum, painted steel or stainless steel and even contain protection against chemical agents. There is also the possibility of increasing the Pass Through with some technological solutions, such as the interlocking of doors and locks with an electric or magnetic key.
The operation of a Pass Box is very simple: a person in the external environment opens a door and places the object that must be sanitized. The equipment performs the sterilization and, on the other side, another person removes the item.
Basically, Pass Through It is responsible for sanitizing and decontaminating products, as well as safely connecting two parts of a production process. In this way, particles from outside air do not mix with the filtered air of a cleanroom.
In fact, the equipment is also essential for transferring products between rooms with ratings different in terms of air purity.
If a certain item is in an environment with one classification and needs to move to a room with another classification, the Pass Through is used, always keeping one of the doors closed.
What types of equipment are available?
There are different Pass Through models on the market, especially due to the fact that the equipment can be custom-made according to the needs of the industry's production line. So the options and sizes are quite variable.
In production areas, for example, it is common to use partitions, doors, white steel sheet lining, stainless steel and glass windows.
In corporate restaurants, it may be interesting to use a hot Pass Through for main dishes and a refrigerated Pass Through for salads and desserts.
The equipment would help maintain the quality of the food, prevent exposure to bacteria and, of course, ensure the proper temperature.
In addition to the steel or aluminum finish, the Pass Through can be upgraded with an exhaust duct, UV lamps, guillotine door and air supply and return, for example, according to production needs.
In the case of insufflation and return, the Pass Through can be considered a small Clean Room, with all the necessary parameters, due to its own systems of filtering that further guarantee the quality and purity of the product to be transferred.
The dimensions of the equipment also vary according to the production need and depend on the size of the objects that will pass through it.
Therefore, it is important to consider its implementation when designing the Clean Room, considering the activity and materials that will need to go through the Pass Through.
How important is the Pass Through for Clean Rooms?
The crossing boxes are intended to prevent clean areas from being contaminated, which is essential to guarantee safety and hygiene in the production process, in addition to the quality of the products.
In Clean Rooms, the equipment is essential because it interconnects parts of the process through double-glazed doors and an interlocking system with closing that prevents two doors from being opened simultaneously, which guarantees a uniform air flow and perfect decontamination. of products.
The hygiene and decontamination of products in production processes is essential in different industries - which is usually required in resolutions - to ensure manufacturing safety and the quality of food, medicines and other items. To transfer an object from one environment to another, between rooms with different classifications, for example, the Pass Through is used, or Passage Box, which consists of an aluminum or steel structure, with doors on both sides, which performs sterilization and connects production stages, a very important functionality also for environmental control in Clean Rooms.
