Deiiang™ Static Passbox

Description

The Deiiang™ Static Passbox is a passive transfer chamber that utilizes room pressure differentials for contamination control. Unlike dynamic models, it operates without internal fans or HEPA filters, making it ideal for areas with established pressure cascades. Designed by Deiiang Jason.peng, it complies with ISO 14644-1 cleanroom standards and GMP guidelines for material transfer applications.

Application Fields
This equipment serves critical roles in:

• Pharmaceutical manufacturing: Transferring packaged components between ISO 7 and ISO 8 areas

• Electronics assembly: Moving tools between controlled environments

• Food processing: Maintaining hygiene standards during ingredient transfer

• Research laboratories: Preventing cross-contamination between experimental zones

Features
Key characteristics include:

• Interlocking doors: Mechanical or magnetic system prevents simultaneous opening

• Stainless steel construction: 304 SUS with #4 brushed finish (Ra <0.8 µm)

• Visual indicators: Red/green signal lights show occupancy status

• Seamless welds: Eliminate particle accumulation points

• Transparent panels: 5mm tempered glass for full visibility

Advantages
The Deiiang™ solution offers:

• Energy efficiency: Zero power consumption during operation

• Cost savings: 40% lower initial investment versus dynamic models

• Maintenance reduction: No filter replacements or motor maintenance

• Space optimization: Compact design with internal volumes from 0.5-2.0 m³

• Quick installation: Simple integration into existing cleanroom walls

Usage Methods
For proper operation:

1. Verify pressure differential >5 Pa between rooms

2. Place items from lower-class side, close door securely

3. Retrieve from higher-class side after indicator confirmation
   Regular cleaning with IPA solutions and gasket inspection, as specified by Deiiang Jason.peng, ensures long-term performance.
