Some major areas that require this unit include the pharmaceuticals, hospitals, medicine and drug industries, liquid crystals manufacturing companies, optical industry, precisely set machinery, etc.

This buying guide presents you with a number of features, specifications, and applications of this product, also with the benefits and working principles followed by it, so let’s begin.

Testing of HEPA Box

What is a HEPA Box?

A HEPA Box is an equipment that fits in all the places where static air pressure is needed. Defining this device in exact words, it is a terminal device present in air systems.

In air handling systems, it plays a very essential role, as it optimizes the air pressure to a sustained level.

Finally, it establishes an air pressure level appropriate for the high-efficiency filters.

Commonly it comes with an air diffuser, high-efficiency filter, and a valve on demand, with the basic purpose of regulating air pressure.

It comes with a string grid that can be easily fitted into the ceilings without the fear of damage. HEPA Box’s resistance to corrosion and moisture absorbance contributes to its long life.

The component that provides 99.99 % filtration efficiency in trapping small-sized contaminating particles is the high-efficiency HEPA filter.

Its working consists of three main procedures including the impaction, interception, and diffusion phenomenons.

What is the Working Procedure of the Filter in the HEPA Box?

It has the potential to clean and purify the air up to 99.99%. The primary filter that HEPA Box possesses is extremely fine, and the diameter is approximately 0.3 microns. So it can trap even very small-sized particles.

This unique filter is very rigorous and fills the filtration requirements of many applications. The air system filter comes with the label HEPA. And you must be aware that such a filter comes with the function of filtering air.

What are the Filtration Mechanisms Followed by the Filters of the HEPA Box?

For the smooth and top-class performance of the HEPA Box, there are several mechanisms involved.

They collaborate and come up with a well-organized performance. Following are the mechanisms;

1. Interception
2. Impaction
3. Diffusion 

Interception:

This is the mechanism that occurs in the air system. Here all the particles are trapped in the airflow.

They stay there as long as they do not touch the clean room HEPA filter. These particles get stuck here and do not pass the filter.

Impaction:

Impaction is followed by interception. In this step, the large particles get trapped. The particles are broken down into small fiber structures. Their size shrinks, and they get embedded in the filter.

Diffusion:

This mechanism acts like a security guard on the door. It acts as a stopper when the particles are moving in a zigzag pattern.

This movement of particles is to pass this air through the filter. The diffusion process enhances the chance of particles being trapped in the filter.

As mentioned above, the air that gets out of the filter is 99.99% clean. This indicates how much HEPA Box is necessary for the air cleaning system.

Why is HEPA Filtration Preferred in a HEPA Box?

HEPA Box is considered the main element in the air filtration world. The reason behind that is it can handle different filtration levels. In maintaining the integrity of the place, HEPA filters are the best choice.

They are strongly recommended by experts, particularly for precise filtration results or for people who are allergic to things.

HEPA Filters are very efficient in that they drain out all the bacteria, fungal spores, pet dander, lint dust, dust mites, pollens, etc.

Talking about the other filters, they become less efficient with time. But HEPA filters are incredibly great as they are good even after six months of the time period.

Every filter has its own life so you can get the idea that you need to change it by seeing the color of the filter as it will change its color from white to brown.

It is preferred to grab interchangeable filters for your HEPA Box because reusing the filters or cleaning the filters is quite a hectic task.

This box can be commonly employed in incubators, warming beds, and different testing laboratories.

What are the Different Categories of the HEPA Filters in a HEPA Box?

To meet the standards of the different functions of the HEPA filters, there are many types of these filters, or more precisely, different grades of these filters.

These grades decide how good the filter is. Generally, it ranges from H10-H12. But there are more advanced HEPA filters now.

There are also H13-H14 grade filter papers. These are used in more intact medical laboratories. The H10-H12 traps particles of size 1 diameter and purifies the air up to 85-99.95%.

On the other hand, highly advanced filters ranging from H13-H14 are designated for medical purposes.

The pharmaceutical companies, the LCD industry, and electronic control rooms have to install HEPA Boxes in their places because they are perfect for removing harmful toxic particles.

The web in these is so dense that it even traps very short particles in them, hence the efficiency rate of HEPA filters is the highest.

What is the Construction of the HEPA Box?

Here comes the construction of the HEPA Box. Let’s get straight into the procedure and materials used in its construction:

• The depth varies with the filter, respectively.

• You can get it with filters or also without filters.

• The standard module comes with two doors and a smaller one with a single door.

• There are four positive pressures, spring-tensioned clamping bolt, swing arm. On HEPA filters, the hand crank puts smooth pressure.

• The frame is made of galvanized steel with 4 integrated sides and mounting flanges on the outside. It is present at the inlet and outlet points.

How Many Air Supply Options are Available for a HEPA Box?

There are two types of air supply options of HEPA Box:

1. Top Supply: In this, the air is supplied from the top portion of the box.
2. Side Supply: In this, the air is supplied from the side of this box.

What is the Recommended Time for Replacing the HEPA filter in your HEPA Box?

The best way to save and enhance the life of your HEPA filter is to add a pre-filter which will reduce the workload on the main filter.

It is essential to replace these pre-filters once a year. This step can enhance the life of your main HEPA filter for around 5 years.

In case your system has no prefilters, you must change the HEPA filters once every year to reduce the accumulation of dirt and debris which can clog the filter.

Due to the thick design of the HEPA filter, its clogged state can interrupt the overall function of your filtration equipment, so timely replacement is essential.

When you replace the old filter with a new one, the old one must be sent to a biowaste treatment setup for final treatment and destruction.
