A Pass Box is a sealed box installed between areas with equivalent cleanliness levels. It allows the transfer of materials, documents, and tools without the need for personnel movement, thereby minimizing the risk of cross-contamination between cleanrooms.
Pass Boxes do not have air filtration systems.
Pass Boxes are designed with interlocking doors on opposite sides, ensuring that only one door can be opened at a time. This interlock mechanism prevents direct airflow between different areas, maintaining the integrity of the cleanroom environment.
Some Pass Boxes are equipped with ultraviolet (UV) lights to sterilize the working area, effectively neutralizing any microorganisms on the materials being transferred. The UV lights are installed and set up safely for personnel.
A static pass box is ideal for transferring materials between rooms with the same level of cleanliness. They are not suitable for transferring materials between areas with different cleanliness classifications because they lack air handling systems, HEPA filters, pre-filters, etc., which prevent contamination, dust, and bacterial infection.
In cases where materials need to be moved between areas with different cleanliness levels, a dynamic pass box or Dynamic Pass Box is a more appropriate choice.
Static pass boxes are widely used in industries such as pharmaceuticals, biotechnology, and electronics manufacturing, where maintaining a contamination-free environment is crucial. They are typically installed in walls between cleanrooms of the same cleanliness level, facilitating the transfer of materials such as tools, documents, or samples without affecting the controlled environment.
Stainless Steel: Depending on the actual needs of the customer, the main frame can be made from stainless steel 304, 201, 430, or 316.
Electrostatic Powder Coated Steel: The electrostatic powder coating has a protective layer that prevents corrosion and oxidation.
The principle of the interlock system is that when one door is open, the other doors must remain closed. Interlock is also known as airlock or interlock.
Customers can choose between electrical interlock or mechanical interlock.
The Emergency Stop Button is used in the device for the following purposes:
Prevent Accidents: The emergency stop button allows operators or personnel to quickly halt the operation of machinery or equipment in case of an emergency, helping prevent accidents and protect human life.

Pharmaceuticals: Pass Boxes are used to transfer materials between different areas within a pharmaceutical manufacturing facility, such as the mixing area and the filling area.
Electronics: Pass Boxes are used to transfer components and materials between different areas within an electronics manufacturing facility, such as the assembly area and the testing area.
Food and Beverage: Pass Boxes are used to transfer food and beverage products between different areas within a food processing facility, such as the preparation area and the packaging area.
Medical: Pass Boxes are used to transfer medical supplies and equipment between different areas within a healthcare facility, such as the operating room and the sterile processing department.
Regular Cleaning: Clean the interior and exterior surfaces with suitable disinfectants to prevent the buildup of contaminants. The choice of disinfectant depends on the material of the main frame.
UV Lamp Maintenance: If equipped with UV lamps, monitor the lamp's operating hours and replace them as recommended by the manufacturer to ensure effective sterilization.
Interlock System Check: Periodically inspect the interlock mechanism to ensure that both doors cannot be opened simultaneously. Any issues should be promptly addressed to prevent potential contamination risks.
