In controlled environments like cleanrooms, laboratories, and pharmaceutical manufacturing units, pass boxes are essential for transferring materials between areas of different cleanliness classifications without risking cross-contamination. At Pillar 9 TAE India Pvt. Ltd, we offer both Static Pass Boxes and Dynamic Pass Boxes, each serving distinct roles in contamination control. Understanding the differences between them is crucial for selecting the right solution based on your operational needs.
Static Pass Boxes are non-ventilated transfer chambers designed to move materials between two equally clean or unclassified areas. They do not have airflow systems, making them ideal for transferring items that do not emit particulates or require air handling. Static units are typically equipped with interlocking doors, UV germicidal lamps, and smooth stainless-steel interiors that are easy to clean and disinfect. These pass boxes are economical, easy to install, and require minimal maintenance, making them suitable for lower-risk environments like quality control labs or packaging areas.
Dynamic Pass Boxes, on the other hand, are equipped with HEPA or ULPA filters, motorized blowers, and pressure differentials. They are designed for transferring materials from non-clean to clean areas (or between areas of different cleanroom classifications). The internal airflow—usually vertical or horizontal laminar—flushes out contaminants before allowing transfer, ensuring the integrity of the cleaner environment. Dynamic pass boxes are essential in high-risk zones such as sterile pharmaceutical production, BSL labs, and electronics cleanrooms, where air purity is non-negotiable.
In terms of benefits, static pass boxes offer cost efficiency and simplicity, while dynamic pass boxes provide enhanced contamination control and regulatory compliance. Both types support interlocking systems to prevent simultaneous door openings, but only dynamic units actively contribute to maintaining cleanroom integrity.
In summary, the choice between Static and Dynamic Pass Boxes depends on the cleanliness levels of the adjacent rooms, the nature of the materials being transferred, and the contamination risk involved. At Pillar 9, we help you make the right decision by offering customized, compliant, and performance-optimized solutions tailored to your facility’s workflow and biosafety requirements.
