company news about Classification of Pass-Through Windows

Pass-through windows can be categorized based on their design, functionality, and application requirements. Below are the main classifications:

1. By Airflow System

• Static (Gravity) Pass-Through – Uses natural air pressure differentials; no mechanical airflow. Suitable for low-risk transfers.

• Dynamic (Forced-Air) Pass-Through – Equipped with HEPA-filtered fans to actively remove contaminants. Ideal for high-cleanliness areas (ISO Class 5-8).

2. By Sterilization Method

• Basic UV Pass-Through – UV-C lamps disinfect surfaces before transfer.

• Vaporized Hydrogen Peroxide (VHP) Compatible – For sterile environments requiring bio-decontamination.

• Autoclave-Compatible – Made of materials that withstand high-temperature sterilization.

3. By Industry-Specific Design

• Pharmaceutical Pass-Through – GMP-compliant, with smooth surfaces for easy cleaning.

• Electronics (ESD-Safe) Pass-Through – Anti-static materials to protect sensitive components.

• Biosafety Pass-Through – Airtight sealing and negative pressure for hazardous materials.

4. By Door Mechanism

• Swing Door – Hinged doors, space-efficient for small cleanrooms.

• Vertical Lift Door – Motorized sliding doors for hands-free operation.

• Rolling Shutter – High-speed transfer for frequent material movement.

5. By Smart Features

• Manual Pass-Through – Basic operation with mechanical interlocks.

• Automated Smart Pass-Through – Integrated sensors, RFID tracking, and IoT connectivity for data logging.

These classifications help industries select the optimal pass-through window for contamination control, efficiency, and compliance with regulatory standards (ISO, FDA, EU GMP).
