Dynamic Pass Box (DPB) — Description

A Dynamic Pass Box is a specialized equipment used in cleanroom environments to transfer materials between areas of different cleanliness levels while minimizing the risk of cross-contamination. It serves as an air barrier between two clean zones, ensuring that particulate contamination does not enter the higher-grade clean area during material transfer.

Unlike a static pass box, the dynamic pass box is equipped with a HEPA filter (High Efficiency Particulate Air filter) and a blower unit that continuously purifies the air inside the chamber during operation. This ensures that any particles brought in with the materials are effectively removed before the pass box doors are opened to the cleaner side.

Construction and Design

• Material: Constructed from high-quality SS 304 or SS 316 stainless steel, with smooth, crevice-free surfaces for easy cleaning and to prevent microbial growth.

• Doors: Equipped with electromagnetic interlocking that allows only one door to open at a time, maintaining pressure differentials and air cleanliness.

• Airflow System: Incorporates a HEPA filter (typically 99.97% efficiency at 0.3 microns) and pre-filter, ensuring Class 100 (ISO 5) air quality inside the chamber.

• UV Germicidal Lamp: Provided (optional) for additional decontamination when not in use.

• View Panels: Toughened glass panels for visibility during transfer.

Working Principle

1. Material is placed inside the pass box from the less clean area.

2. The blower-fan unit activates, circulating air through the HEPA filter to remove airborne contaminants.

3. After the purification cycle, the interlocking system allows the opposite door (clean side) to open, ensuring only decontaminated materials pass through.

4. The cycle prevents air turbulence and maintains cleanroom integrity.

Key Features

• Continuous clean air circulation with HEPA filtration.

• Electromagnetic door interlocking system for contamination control.

• SS 304/316 body with smooth, easy-to-clean design.

• UV light and hour meter (optional) for sterilization monitoring.

• Low noise and vibration operation.

Applications

• Pharmaceuticals and biotechnology industries

• Microelectronics and semiconductor manufacturing

• Food processing and packaging areas

• Hospital and laboratory cleanrooms
