Pass Box Manufacturer, Supplier & Exporters

A Pass Box is a sealed, stainless steel enclosure used in cleanrooms and controlled environments to transfer materials or equipment between two areas of different cleanliness levels without compromising the sterility or air quality of either area. It helps prevent contamination by minimizing direct human traffic between zones.

Core Functions and Purpose

Material Transfer – Safely move materials, tools, or equipment between areas of different cleanliness levels without direct human contact.

Contamination Prevention – Minimize 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.
