Cleanroom Pass Box Solutions by Cronax Industries

Pass Box in Pharma and Cleanroom Applications

A pass box in pharma and cleanroom environments is a critical component for contamination control. It allows the safe transfer of materials between areas of different cleanliness levels without compromising the controlled environment.

Whether you require a static pass box or a dynamic pass box, Cronax offers high-quality, durable solutions to meet the stringent hygiene and safety standards of pharmaceutical and cleanroom industries.

What is a Cleanroom Pass Box?

A cleanroom pass box is an enclosed chamber installed in the wall between two clean areas or between a clean and non-clean area. It facilitates the transfer of materials without allowing contaminants to enter the controlled environment.

Key Benefits:

• Prevents cross-contamination

• Minimizes personnel movement, reducing air contamination risks

• Ensures material transfer under controlled conditions

Types of Pass Boxes

1. Static Pass Box

A static pass box is used for material transfer between areas of the same cleanliness level. It does not have air filtration or airflow systems. The static design is simple, cost-effective, and suitable for pass box clean room applications where airflow control is not required.

Applications:

• Laboratories

• Pharmaceutical facilities

• Research centers

• Cleanrooms with identical pressure zones

2. Dynamic Pass Box

A dynamic pass box comes with built-in HEPA filters and motorized blowers to ensure continuous airflow inside the box during material transfer. It is ideal for transferring materials between areas with different cleanliness classes.

Features:

• HEPA Filtration (99.97% efficiency at 0.3 microns)

• Interlocked doors to prevent simultaneous opening

• UV germicidal light (optional)

• SS304/316 construction for hygiene and durability

Applications:

• Pharmaceutical manufacturing units

• Hospitals and medical device production

• Semiconductor industries

• Biotechnology labs
