Pass Box Manufacturer, Suppliers & Exporters

A pass box (also called a pass-through box or transfer hatch) is a compact, airtight chamber built into the wall between two controlled environments to allow safe transfer of materials without exposing the receiving area to contaminants. Pass boxes form a physical barrier that limits particle and microbial ingress during transfers and are widely used where clean-room integrity is critical. Their core functions are to provide contamination-controlled material transfer, reduce personnel movement between zones, and enable decontamination or sterilisation cycles (UV, VHP, HEPA airflow) within a confined space before entry into the clean zone.

Core Functions and Purpose

• Material Transfer: Safely move materials, tools, or equipment between areas of different cleanliness levels without direct human contact.
• Contamination Prevention: Minimise the risk of airborne particles, dust, and microbes entering controlled environments.
• Air Quality Maintenance: Maintain cleanroom integrity by reducing air turbulence and cross-contamination.
• Ensure Sterility: Keep materials and equipment sterile while moving between zones.
• Support Cleanroom Protocols: Comply with ISO and GMP standards in pharmaceutical, biotech, and semiconductor industries.
• Reduce Human Traffic: Limit personnel movement between cleanroom zones, reducing contamination risk.

Product Types & Specifications

1. Manual Pass Box

• Operated without electrical components.
• Doors on either side are interlocked mechanically to prevent simultaneous opening.
• Suitable for low-to-medium hygiene environments.
  

2. Automatic / Electric Pass Box

• Equipped with electric interlocks and automatic doors.
• Doors can be opened with push buttons or sensors.
• Reduces manual handling, minimises contamination risks.
  

3. Single-Door Pass Box

4. Double-Door Pass Box

• Doors on both sides open into separate cleanrooms or controlled environments.
• Ensures better segregation of contamination zones.
