A dynamic pass box is an advanced contamination control device used to transfer materials between two cleanroom areas of different cleanliness levels. Unlike static pass boxes, a dynamic pass box in clean room environments features an active HEPA-filtered air circulation system that continuously purges airborne particles.
Step 1: Material Placement
An operator on the dirty side (lower cleanliness area) places the material inside the pass box through the first door.
Step 2: Door Interlocking Activation
The electromagnetic interlocking system prevents both doors from opening simultaneously, ensuring unfiltered air never enters the clean side.
Step 3: Auto-Cleaning Cycle (Air Shower Effect)
The dynamic pass box controller activates the blower motor, drawing air through the pre-filter and HEPA filter. HEPA-filtered air is circulated inside the chamber at 0.45-0.75 m/s velocity, removing particles from material surfaces.
Step 4: UV Sterilization (Optional)
If equipped with UV light, the material is exposed to germicidal UV-C radiation for a preset duration (typically 5-15 minutes), killing surface microorganisms.
Step 5: Material Transfer
The operator on the clean side opens the second door only after the interlock confirms the first door is closed and the cleaning cycle is complete.
Step 6: Material Retrieval
The material is safely retrieved on the clean side without any contamination transfer.

Proper dynamic pass box installation is critical for optimal performance and compliance with cleanroom standards.
Step 1: Wall Preparation
Cut the required opening in the cleanroom wall. Ensure the opening is level, square, and free from debris.
Step 2: Position the Pass Box
Insert the dynamic pass box into the wall opening. Ensure it is flush with both sides of the wall and level in all directions.
Step 3: Secure the Unit
Use mounting brackets or flanges to secure the pass box to the wall structure. Ensure no movement or vibration.
Step 4: Seal All Gaps
Apply pharmaceutical-grade silicone sealant around all gaps between the pass box and wall. This prevents air leakage and maintains pressure differential.
Step 5: Electrical Connection
Connect the unit to 220/230V single phase power supply. Ensure proper earthing. The dynamic pass box controller should be easily accessible.
Step 6: HEPA Filter Installation (if shipped separately)
Install the HEPA filter in its housing. Ensure proper sealing and gasket compression.
Step 7: Test All Functions
Step 8: Perform DOP Test (if required)
For pharmaceutical applications, conduct HEPA filter integrity testing using DOP/PAO challenge method.
We recommend professional installation by trained technicians to ensure proper sealing, electrical safety, and compliance with regulatory requirements.
A dynamic pass box in clean room environments is essential for industries requiring strict contamination control.
1. Active Contamination Control
HEPA-filtered air circulation continuously removes airborne particles, achieving ISO Class 5 cleanliness during material transfer.
2. Surface Sterilization
UV light kills up to 99.9% of surface microorganisms before materials enter critical areas.
3. Regulatory Compliance
Helps pharmaceutical companies meet GMP, Schedule M, and USFDA requirements for aseptic material transfer.
4. Operational Efficiency
Auto-cleaning cycle ensures consistent contamination control without manual intervention.
5. Filter Monitoring
Magnehelic gauge provides real-time pressure drop reading, alerting when HEPA filter replacement is needed.
6. Low Noise Operation
Dynamically balanced motor-blower ensures ≤65 dB noise level – quieter than normal conversation.
