6. Working Principle

The working principle of the Aluminum Pass Box can be summarized as High Sealing + Interlocking + Physical Isolation:

Operation Process:

1. Operator on the low-cleanliness side opens the outer door

2. Places materials inside the chamber

3. Closes the outer door (interlock activates)

4. Operator on the high-cleanliness side opens the inner door

5. Removes materials and closes the inner door, completing transfer

Interlock Principle:

• When one door is opened, the opposite door is automatically locked

• Ensures air from both zones does not directly communicate

• Prevents pressure differential disruption and contaminant entry

Purification Principle (Optional):

• HEPA filter circulates and filters internal air

• UV lamp irradiates material surfaces for disinfection

• Ensures cleanliness of both materials and environment during transfer

7. Application Areas

Aluminum Pass Boxes are widely used in the following industries:

1. Pharmaceutical and Drug Manufacturing-

• Transfer of raw materials, excipients, semi-finished products between different cleanroom grades

• Complies with GMP standards

• Supports high-frequency material turnover

2. Biological Laboratories

• Transfer of biological reagents, cell cultures, microbial specimens

• UV sterilization function ensures experimental safety

• Suitable for BSL-2 and above laboratories

3. Electronics and Semiconductor Manufacturing

• Clean transfer of chips, circuit boards, precision components

• Reduces dust and static interference on components

• Improves product yield and production stability

4. Food Processing Industry
