Dynamic Pass Box Working Detail with PVC Duct and Solder Connection

This AutoCAD drawing presents a dynamic pass box working detail with PVC duct and solder connection used in controlled airflow systems and technical equipment installation. The drawing illustrates the structural arrangement and working configuration of a dynamic pass box system, including internal airflow pathways and connection components. The design shows the integration of PVC ducting with a diameter reference of approximately 16 m MOE used for air transfer between controlled environments. The drawing also includes connection detailing using solder joints with tin material combined with approximately 50 percent huincha rubber and plastic sealing layers to ensure proper insulation and airtight installation. These components help maintain air control and prevent contamination between spaces.
