Why do we need Dynamic and Static Pass Boxes

Schematic Engineering Industries specialises in the comprehensive design, manufacturing, supply, and installation of various containment equipment essential for the Pharmaceutical and Chemical industry sectors. One crucial component in our repertoire is the Pass Box, a pivotal piece of equipment widely employed across diverse industries.

Pass Boxes typically fall into two primary categories:

• Static Pass Boxes
• Dynamic Pass Boxes

While both serve similar purposes, they exhibit fundamental differences.

_{Static Pass Boxes}

These boxes facilitate the transfer of materials between two clean environments with minimal or no human intervention. Equipped with an electromagnetic interlock system between the two doors, a visual cue in the form of an LED light indicates when any door is open.

_{Dynamic Pass Boxes}

Designed for transferring materials from a non-controlled environment to a controlled one, Dynamic Pass Boxes feature two interlocking doors on either side to safeguard the controlled environment during transfers. The interlock guard system ensures that both doors are opened simultaneously, preventing any potential cross-contamination.

In essence, the primary objective of Pass Boxes is to establish a barrier between different areas and eliminate particulate load, if present, on the surface of transferred objects. Static Pass Boxes are typically installed in manufacturing areas, filtering incoming air to maintain a dust-free and contaminant-free environment. On the other hand, Dynamic Pass Boxes utilise an interlock guard system to control both the inlet and outlet, ensuring simultaneous door opening to prevent cross-contamination.

These boxes find applications in various settings, including:

• Clean Rooms
• Laboratories
• Hospitals
• Pharmaceutical plants
• Llight-industrial environments
