Maintaining contamination control during material transfer is critical in regulated spaces. The Pass Through Box developed by yd-purification supports secure, low-risk transitions between cleanrooms or between clean and general zones. These systems enable the safe handover of tools, documents, and materials without allowing direct personnel crossover, reducing the chances of particle intrusion and pressure imbalance.
These units are constructed using corrosion-resistant steel, tempered glass, and smooth interior finishes. Each element is selected to support fast disinfection and long-term durability under frequent use. Mechanical or electronic interlocks ensure only one door opens at a time, preventing airflow disruption or room cross-exposure. Some variants include UV sterilization, HEPA filtration, or differential pressure alarms to match specialized cleanliness requirements.
Functionality adapts to various facility layouts. Options range from mechanical boxes for basic zone division to air shower-type pass throughs for particle-sensitive transitions. Surface-mounted and wall-embedded configurations are available to suit both new and retrofit installations. Vision panels and indicator lights provide user visibility, while ergonomic handles and soft-close hinges allow for stable daily operation.
These systems are commonly applied in industries such as pharmaceuticals, biotechnology, food processing, and semiconductor manufacturing. They support documentation movement, reagent delivery, or equipment transfers—all without violating cleanroom standards. Proper use reduces microbial load and mitigates the spread of airborne or contact-based contaminants.
Routine maintenance is simplified through accessible panels and modular designs. The interior construction prevents dirt traps or static buildup, ensuring that cleaning protocols can be efficiently executed. All units undergo air leakage testing, mechanical durability trials, and surface integrity inspections before release.
