An “SS L-Type Static Pass Box” refers to a pass box that is constructed using stainless steel (SS) materials and has an “L” shape design. A static pass box is a specialized piece of equipment used in controlled environments such as cleanrooms and laboratories to transfer materials between two areas while minimizing the risk of contamination. The “L-Type” likely indicates the design of the pass box, and the use of stainless steel enhances durability and cleanliness. Here’s a breakdown of the terms:

1. SS (Stainless Steel): The pass box is made using stainless steel, a material known for its resistance to corrosion, durability, and ease of cleaning. Stainless steel is often used in environments where cleanliness and hygiene are crucial.
2. L-Type: The “L-Type” design suggests that the pass box has an “L” shape configuration. The specifics of this design can vary, but it generally implies that the pass box has two connected compartments that meet at a right angle, forming an “L” shape.

Key features of an SS L-Type Static Pass Box might include:

• Two Compartments: The pass box typically consists of two compartments, each with a door. One compartment faces the “clean” side (e.g., a cleanroom), and the other compartment faces the “less clean” side (e.g., outside the cleanroom). This design prevents direct airflow exchange between the two areas, minimizing the risk of contamination.
• Interlocking Doors: The doors of the pass box are designed to prevent both doors from being open at the same time. This helps maintain the controlled environment within each compartment.
• HEPA/ULPA Filters: Some pass boxes may be equipped with HEPA or ULPA filters to ensure that the air entering the clean side is filtered and free from particles.
• UV-C Sterilization: In some cases, pass boxes may feature UV-C germicidal lamps to disinfect the materials being transferred before they enter the clean side.
• Smooth Interior Surfaces: The interior surfaces are typically designed to be smooth and easy to clean, reducing the potential for particle accumulation.
• Control Panel: Pass boxes may have a control panel for adjusting features such as UV-C lamp operation and setting interlocking mechanisms.

L-Type static pass boxes are commonly used in settings where controlled material transfer between different cleanliness zones is necessary to maintain the integrity of the controlled environment. When considering an SS L-Type Static Pass Box, ensure that the design and features match your specific contamination control needs and adhere to industry standards for cleanliness and safety.
