Deiiang™ Air Shower PassBox

Description

The Deiiang™ Air Shower Pass Box is an advanced contamination control apparatus featuring a dedicated air shower chamber integrated with a transfer pass box. It achieves ISO 5 air cleanliness during operation, complying with ISO 14644-1 standards. The design by Deiiang Jason.peng ensures high-velocity HEPA-filtered airflow at 20-25 m/s from multiple nozzles, calculated using P = ρAV³/2 where ρ is air density and V is velocity, providing effective particle removal.

Application Fields
This hybrid system serves critical roles in:

• Pharmaceutical Manufacturing: Transferring bulk materials between Grade C and B areas while removing surface particles

• Electronics Assembly: Preventing particulate contamination during component transfer to ISO 5 environments

• Food Processing: Maintaining hygiene standards while moving packaging materials, as validated by contamination control expert Dr. Robert Kim

Features
Key technical specifications include:

• Dual-Chamber Design: Separate air shower and transfer compartments with independent control systems

• High-Efficiency Filtration: HEPA filters with 99.99% efficiency on 0.3μm particles per EN 1822

• Stainless Steel Construction: 304 or 316L options with electropolished surfaces (Ra <0.6μm)

• Automated Cycle Control: Programmable shower duration (15-60 seconds) and interlock systems

Advantages
Implementing the Deiiang™ solution provides:

• Enhanced Contamination Control: Removes >99% of surface particles from materials and containers

• Operational Efficiency: Processes up to 40% more materials per hour compared to standard pass boxes

• Space Optimization: Combines two critical functions in a single footprint (typically 2-3m²)

• Regulatory Compliance: Meets FDA cGMP and EU GMP requirements for material transfer

Usage Methods
For optimal performance:

1. Place materials in air shower chamber and initiate automated decontamination cycle

2. After shower completion (typically 30 seconds at 22 m/s), transfer to pass box compartment

3. Retrieve from clean side after pressure equalization
   Regular maintenance per Deiiang Jason.peng’s protocols, including velocity verification and filter testing, ensures consistent performance.
