What is a Pass Box?
An Open Pass Box Showcasing its Interior
A pass box is an important accessory for your cleanroom whose main aim is to help transfer small items between the non-clean area and the clean area. When it is in use, you will find that you no longer have to open the cleanroom door frequently. As a result, this minimizes the entry of the unfiltered air into the cleanroom.
Once you set up the pass box, you will quickly notice that it has multiple applications in different fields. It is why you can get different options from Sunnyda such as pharmaceutical pass box, specimen pass box, lab pass box, medical pass through pass box and more.
You are likely to find some online content referring to the pass box as a pass-through box or a pass-through cabinet. In case you encounter such, just know it is the same thing.
What are the Types of Sunnyda Pass boxes?
The two types of Sunnyda pass boxes include dynamic pass boxes and static pass boxes. They will have multiple similar features that would make them work as pass boxes. Some of the similar features include UV lights, fluorescent lamps, interlocking doors, and mostly made of stainless steel material.
Even with such similarities, there will be other differences to help you understand what you will get with whichever model you decide to get.
- The static pass box is commonly used for transferring the materials between two different clean areas. Their design allows them to work without personnel movements. As for the dynamic pass box, it would be great for passing materials between a controlled environment and an uncontrolled environment. A static pass box cannot be used to transfer the materials between a non-clean area and a clean area.
Static Pass Box
- A dynamic pass box will also have interlocking doors on both sides of the pass box. They help protect the clean area from pollution during the transfer process. A static pass box will still have an interlocking mechanism, but it will be between two doors. There can be an LED indicator to help show which door is open.
- In a dynamic pass box, only one door can be open at a time. This ensures there has been proper decontamination before moving the materials to the cleanroom and vice versa. The static pass box does not have this feature. It is only used to transfer materials between two clean areas.
- A dynamic pass box will have a filter to ensure the air inside is also filtered to remove the contaminants. You can also adjust the air velocity depending on what you need to pass through the box. The dynamic pass box can also have a motor blower to blow out the dust particles from the materials. The static pass box does not have a filter, but rather works as an airlock device. Its job is to prevent the ambient air from getting into the cleanroom and the clean air from getting out of the cleanroom.
There can still be more differences between these two types of pass boxes. What is crucial is for you to understand how the two work and focus on picking the right one, depending on your needs. Always consult Sunnyda in case you need more information about the types of pass boxes or how a pass box works.

Why Choose a Sunnyda Pass box?
Since there are many companies that can make a pass box, why pick the Sunnyda pass box? Here are some quick reasons Sunnyda still remains a top choice for most people.
The pass box reduces contamination
This is probably the most common reason why someone would choose to get a pass box from Sunnyda. The pass box will reduce the overall foot traffic getting into the cleanroom. Considering that some people are only there to deliver cargo, it is best if they used the pass box.
Also, not all people have to go through the decontamination process since they will not be getting into the cleanroom. All they need to do is put the cargo into the pass box and someone else will pick it up on the other side.
The pass box can increase overall productivity
Rather than decontaminating the cargo manually, it will now be automated. So, less time can be spent on decontaminating the materials and rather focus more on working on different projects.
Another good example is the automated controls on the pass box. Rather than having someone employed to operate the pass box manually, it is now all automatic.
Still, the operations of a pass box are scalable. This means that they can always be tailored to the user’s needs. That is how you end up with a pass box that generally improves productivity.

Multiple customization options
Sunnyda also gives the users the option of customizing the pass box as much as possible. There is the option of choosing the size, material, and more. This means that you can tailor the pass box to work great for your application. It is understandable that different cleanrooms would have different needs.
Sunnyda has some of the best prices for those looking for a cleanroom pass box. Well, as much as the price can vary based on design, size, material, and application, they are still the best prices in the market. Just because they are competitive prices, it does not mean the pass box will not meet your build quality standards. The pass box will still be great in terms of quality too.
Ease of cleaning
A pass box is not hard to clean. For the most part, its working principle will mostly lead to having a clean work area. However, you should ensure that the pass box is cleaned after every use. This is important to ensure there is less contamination each time you have to use it.

What are the Maintenance Needs of a Pass Box?
To use the pass box correctly over the years, you need to follow the proper operating procedure. This means turning on the pass box 15 minutes prior to using it. This will blow the clean air over the pass box work surface to leave it clean before you can introduce cargo into the pass box.
The cargo in the pass box should be oriented properly. This ensures that every dust and particulates can be cleaned off the cargo before it gets into the cleanroom.
Check the laminar flow of the air in the pass box. You might have to make adjustments to the air velocity or service the blower to ensure there is a laminar flow of air. If the laminar flow is not correct, it could easily affect the overall pass box purification performance.
As part of maintenance, you also have to check the filter after three to six months. Visual inspection can help determine if the filter is still good or not. Sometimes you can just vacuum it and it will continue to work great. However, if it is too dirty, consider replacing the filter with a new one for the best performance.
Having a dust particle counter test done will go a long way in helping you understand if the filter is still good or not. If it seems there are too many particles in the cleanroom than necessary, it would be great to consider getting yourself a new filter for the pass box and the cleanroom HEPA box.
Sometimes you might end up with electrical issues. When this happens, let a professional handle them. You might risk electrocution or make it even worse when you decide to repair yourself.
It would be nice if you have a maintenance checklist. This will help you know what you need to repair, replace, or maintain as you use the pass box.

Why is a Pass Box Validation Process Important?
A pass box validation is important so that you can always know if it is working correctly or not. This means you have to carry out several tests as part of the validation process. Here are some of the tests to keep in mind.
- The airflow system test. Here you check the performance of the airflow in the pass box. It should always be in a unidirectional airflow. If it is otherwise, you need to address the issue as soon as possible.
- The HEPA filter integrity test is also important. You could use an aerosol photometer or other notable HEPA filter testing methods. The leakage rate should not go above 0.01%. If the HEPA filter needs replacement, work on it too. Once the filter is replaced, it should be easy to keep the pass box working correctly.
- A particle count might be necessary too. This test is still important to determine if there are many particulates in the work area. If they are too many, you need to check the filters to ensure they are in good working conditions.
