Static Pass Box vs Dynamic Pass Box: Understanding the Differences

Static Pass Box Vs Dynamic Pass Box: Know the Difference

In a cleanroom or contaminant-controlled environment, everything counts, especially when you need to pass materials safely between rooms. And that’s where pass boxes come in. No matter if you’re dealing with a biosafety cabinet manufacturer, a pharmaceutical or a research facility, we can’t stress enough how important it is for these environments to know the difference between a Static pass box and a Dynamic pass box especially if your staff members or workers are handling microbiology materials within your workplace, or have it transferred from one laboratory to another lab.

Static Pass Box What It Is?

A Static Pass Box is a passive, non-ventilated moving clean room transfer device designed to pass items, parts, tools, or documents into a lower cleanroom environment. There are no motor or airflow that’s between, no exposure to germs or bacteria, thanks to its seal. This makes it appropriate for applications where particle movement must be minimized.

They are widely used in laminar flow machine applications, for transferring materials such as samples from an orbital shaker, or seed germination experiment trays when a clean but not necessarily particle-free environment is needed.

What is a Dynamic Pass Box?

Conversely,Dynamic Pass Boxs are with inbuilt HEPA filters and a mechanical blower and its air is moved from the airlock to the storage device. It is appropriate for this system when materials are passed between rooms of differing cleanroom class, or when materials can contaminate. It is often used together with other sterile instruments such as HEATING MANTLE salt spray test chamber sieve shaker machine.

Dynamic pass boxes provide an additional step in decontamination,are beneficial for use in cleanrooms which are high-grade and are used in processes such as water sedimentation in pharmaceutical or food testing laboratories.

Let's Take a Quick Look of Key Differences :

• Airflow: Static has no airflow; dynamic is filtered direct airflow.

• Application: Static is for usage of cleaning between the same cleanroom class while Dynamic is meant for different areas.

• Cost & Maintenance — Static being cheaper and lower maintenance than dynamic which is more expensive but offering superior contamination control.

• Complexity: Static is straightforward; dynamic has electrical and filtration systems.
