Pass Box
Cleanroom Pass Through Boxes for Contamination Control
ElectroStatica designs and manufactures world-class Pass Boxes to ensure contamination-free material transfer in cleanroom and controlled environments. Our pass-through systems are engineered to prevent cross-contamination between classified and non-classified areas by maintaining strict air quality and pressure control.
Available in Static Pass Boxes and Dynamic Pass Boxes, these units are widely used in pharmaceuticals, biotechnology, defense, healthcare, food processing, and electronics industries. Designed with precision, our pass boxes are made from high-grade SS-304 stainless steel, featuring interlocked doors, UV germicidal lamps, and HEPA filtration systems for maximum safety and compliance.
What is a Pass Box?
A Pass Box, also known as a Pass Through Box, is a cleanroom equipment used to transfer materials between two areas of different cleanliness levels without allowing contaminants to enter the controlled environment. It ensures operational efficiency, reduces material handling errors, and maintains sterility in critical processes.
Types of Pass Boxes
- Static Pass Box – Used where material is transferred between clean but same-grade areas, without airflow requirements.
- Dynamic Pass Box – Equipped with HEPA filters and blower units for air circulation, ensuring contamination-free transfer between areas of different cleanliness grades.
