Laminar Flow Pass-Through Windows: The Essential Cleanroom Transfer Solution
Maintaining Cleanroom Integrity During Material Transfers
Laminar Flow Pass-Through Windows (also known as pass boxes) are critical contamination control devices for cleanroom environments. As a professional cleanroom equipment manufacturer, Guangzhou Cleanroom Construction Co., Ltd. provides high-quality pass-through windows that meet international standards for pharmaceutical, biotechnology, and electronics applications.
A. Working Principles of Laminar Flow Pass-Through Windows
Pass-through windows operate on three key principles:
1. Unidirectional Airflow: HEPA-filtered laminar airflow maintains ISO class cleanliness levels during transfers.
2. Interlocking Doors: Prevents simultaneous opening of both sides to maintain pressure differentials.
3. Material Containment: Designed to prevent cross-contamination between cleanroom zones.
B. Types of Pass-Through Windows
There are three main configurations:
Static Pass Box: Basic transfer chamber without airflow, for less critical applications.
Laminar Flow Pass Box: Features vertical or horizontal HEPA-filtered airflow for contamination control.
Air Shower Pass Box: Includes air shower function to decontaminate materials during transfer.
C. Key Applications of Pass-Through Windows
Essential for material transfer in:
- Pharmaceutical manufacturing facilities
- Sterile filling lines
- Electronics cleanrooms
- Biotechnology laboratories
- Hospital compounding pharmacies
- Medical device manufacturing
