Dynamic Pass Box

Product Description

A dynamic pass box, often referred to as an air shower pass box or a clean transfer box, is a piece of specialised equipment used in cleanrooms and other controlled settings to make it easier to move goods while preserving cleanliness and reducing the danger of contamination. It offers a regulated setting for moving things while making sure they are exposed to clean airflow to eliminate particulate matter and pollutants before entering or leaving a cleanroom.

These are a dynamic pass box's main characteristics and capabilities:

1. Dynamic pass boxes are normally constructed as a tiny container with two openings or hatches, one on each side. To reduce particle formation, the enclosure is made of materials like stainless steel or other smooth, cleanable surfaces.

2. The air shower system is the primary component of a dynamic pass box. The device releases a high-velocity, regulated airflow as an object is passed through the pass box, dislodging and removing debris and pollutants from the object's surfaces. High-efficiency filters, air blowers, and nozzles are frequently used in air shower systems to ensure thorough cleaning.

3. Airflow Control: Dynamic pass boxes keep the enclosure's airflow unidirectional. The filtered air is sucked in through the pre-filters, moved through the HEPA filters, and then discharged through the nozzles as a pure, laminar airflow. The airflow arrangement aids in preventing the transfer of outside pollutants.

4. Safety Interlocks: Dynamic pass boxes frequently have safety interlock mechanisms built in to safeguard the integrity of the regulated environment. The direct interchange of air between the clean and unclean sections is avoided by these devices, which make sure that only one door may be opened at once.

5. Particle Monitoring: A few dynamic pass boxes may come equipped with built-in particle monitoring systems that gauge and show the extent of particulate contamination inside the enclosure. As a result, before moving things, operators can check the pass box's cleanliness.

6. Applications: Materials must be transferred between various cleanliness zones, hence dynamic pass boxes are frequently employed in cleanrooms and other controlled settings. They are particularly helpful for moving small pieces of equipment, tools, samples, or papers without affecting the controlled environment's cleanliness.

By lowering the chance of contamination during material transfer, dynamic pass boxes are essential for ensuring the cleanliness and integrity of cleanrooms. They should be properly maintained and operated to ensure its efficiency in minimising particle contamination. They are intended to meet certain cleanliness criteria.
