US ENTERPRISES offers a high-quality range of Static and Dynamic Pass Boxes (SPB/DPB) designed to enable safe, contamination-free transfer of materials between cleanroom areas of different classifications. Built with precision and durability, our pass boxes help maintain the integrity of controlled environments by minimizing cross-contamination and reducing human movement within clean zones.
Whether you're operating in pharmaceutical manufacturing, biotechnology, food processing, healthcare, or electronics, our pass boxes are engineered to support stringent cleanroom standards.
Types of Pass Boxes:
Static Pass Box (SPB): Used between two areas of the same clean classification, with no airflow mechanism. Ideal for transferring sterile or non-particle-generating materials.
Dynamic Pass Box (DPB):Equipped with HEPA-filtered airflow, typically used between areas of different cleanliness levels. Ensures that the air inside the pass box remains clean and pressurized during material transfer.
