Static Pass Box (18” x 18” x 18”) 

A Static Pass Box is an essential component in cleanroom environments, particularly within industries such as pharmaceuticals, biotechnology, electronics, and medical device manufacturing. Designed to facilitate the safe transfer of materials between rooms of different cleanliness levels, the pass box minimizes the risk of airborne contamination and maintains the controlled environment integrity. The 18 x 18 x 18-inch model offers a compact and efficient solution for transferring small instruments, samples, or documentation without requiring personnel to move between clean zones.

Constructed from high-grade stainless steel, usually SS 304 or higher, this static pass box ensures a robust, corrosion-resistant surface that is easy to clean and disinfect. The unit features a double-door system equipped with an interlocking mechanism, preventing both doors from opening simultaneously. This design ensures an effective physical barrier against cross-contamination during material transfer. The interior is designed with smooth, rounded edges, which help eliminate particle build-up and make routine cleaning more efficient.

Unlike dynamic pass boxes, a static pass box does not have internal fans or HEPA filtration. It is specifically used where active air handling is not required, making it suitable for non-viable material transfers between areas of similar cleanliness levels or when the product being transferred does not require an aseptic environment. A transparent viewing panel, typically made from toughened glass or clear acrylic, allows users to monitor the contents without opening the unit.

Additionally, optional features such as UV germicidal lamps, magnetic door locks, door open indicators, and audible alarms can be integrated based on specific operational needs. These additions can enhance sterility and usability, making the unit more versatile across different applications. Overall, the 18 x 18 x 18 static pass box is a critical solution for maintaining hygiene, reducing operational disruptions, and improving safety in highly sensitive cleanroom operations.
