Dynamic Pass Box
Dynamic Pass Box
A Dynamic Pass Box is a controlled transfer chamber designed to move materials between classified areas without compromising cleanliness. By using interlocked doors and HEPA-filtered clean air, it prevents cross-contamination and maintains the sterility of your cleanroom.
URL 3S Pharma Machinery Inc. is a leading supplier of Static and Dynamic Pass Boxes in India, engineered to meet the stringent requirements of pharmaceutical, biotech, electronics, and high-purity manufacturing environments.
Key Features
Design & Construction
- GMP-compliant smooth design for easy cleaning and disinfection
- Double-skin SS 304/316 cabinet with toughened glass doors
- Electro-magnetic door interlocking (only one door opens at a time)
- Air velocity: 0.45 ± 0.05 m/s (90 ± 20 FPM) at 6 inches from the grill
- Low-noise operation: ≤ 65 dB
Air Filtration & Flow
- HEPA Filter H14 for supply & exhaust air (0.3 micron)
- EU6 Grade Pre-Filter with SS 304 flange
- Recirculated filtration system ensures consistent cleanliness
- Centrifugal air blower with variable speed control
- DOP / PAO test port for filter integrity testing
Controls & Instrumentation
- Magnehelic differential pressure gauge
- Feather-touch control panel for blower, lights, and display
- Integrated UV germicidal light & white light
- Electromagnetic locking linked with UV lamp (UV ON = doors locked)
Available Options
- Digital differential pressure gauge with alarm
- Hour meter
- Measurement system for pressure, airflow, or volume flow
- Customized sizes and stainless-steel grades (SS 304/316)
How It Works
- Material is placed inside the pass box from the non-clean side.
- The door automatically locks until the air is filtered and UV sanitization is completed.
- Clean, HEPA-filtered air flows through the chamber, preventing contaminants.
- Once conditions are safe, the cleanroom-side door unlocks.
- Material is retrieved without any direct airflow or contamination risk.
