What is an Air Shower Booth?

In every controlled environment, there has to be an enclosed chamber that prevents the entry of contaminants.

An Air Shower Booth serves as an entryway and controls the entry of contaminants that are present on the clothes, body, and hair of the person entering the clean environment.

It utilizes a high-efficiency filtration system to remove any lint, dust particles, and skin follicles. In this way, the number of airborne particles entering the clean environment stays low.

An Air Shower Booth is designed and constructed according to the international ISO standards. It can be used in a moderate clean room, pharmaceutical clean room, clean room semiconductor, or any other such application.

Usually, it is present between the gowning area and the clean room, laboratory, or manufacturing area.

Every personnel entering the controlled environment has to pass through the booth and has to stay there for one complete cycle.

It can also be placed between two different controlled environments with different cleanliness levels.

L Type Industrial Air Shower for Medical Clean Room

How Does an Air Shower Booth Work?

The working of an Air Shower Booth is very simple. It is a self-contained system that works by using air circulation.

High-velocity air is shot from the nozzles in a manner that each particle follows the path of the particle ahead of it.

This bombardment of particles on the particulate matter displaces the contaminants from the surface. These contaminant particles fall to the ground due to gravity.

As soon as the high-velocity air particles hit the contaminant, they transfer their momentum to the latter which is displaced as a result.

As a person enters the booth, the automatic door is closed and the powerful jets start blowing the air to all angles such that it reaches every part of the body.

Also, this air is filtered and comes straight out of the HEPA or ULPA filtration system.

After one cycle is complete, the automatic door is opened and a person or object can leave the Air Shower Booth.

One cycle lasts for approximately 20 seconds which is sufficient time to deal with surface contaminants. Also, this cycle is directly controlled and regulated by the microprocessor unit.

What is the Operating Sequence of an Air Shower Booth?

The operational sequence of your Air Shower Booth has three pre-programmed sequences:

One Way:

It allows the movement of personnel in only one direction. The person can enter from the booth.

When it is not being used, the door towards the clean side is locked and the one on the unclean side is not.

One can enter from the unclean side, get decontaminated, and then enter the controlled environment.

One Way Two Way:

The Air Shower Booth acts as both the entry and the exit channel into and out of the clean environment.

The microprocessor works by detecting if the person wants to enter or exit and unlocks the door accordingly.

Two Way:

Here in this sequence, the booth is active in both directions. It is much more efficient and convenient because both the doors are unlocked and one can enter or exit at any time.

Also, it deals with hazardous substances as well.

Why Do you Have to Maintain Positive Pressure Inside the Air Shower Booth?

It is important to maintain positive pressure inside an Air Shower Booth so that there is no chance of entry of any other contaminant.

The movement of particles is always encouraged from high pressure to a low-pressure level.

Whenever it is required to move a particle from low to high pressure are, active energy is required.

Therefore, by maintaining positive pressure, you can compel the entry of an incoming particle.

In highly controlled environments and an air shower room, the sole purpose is to obtain the highest level of decontamination.

Therefore there is no external force that goes against the positive pressure to introduce contaminants into the booth.

Thus the positive pressure acts as a barrier.

What is the Significance of Silicone Free Urethane Sealant in an Air Shower Booth?

The silicone-free urethane sealant is useful in an Air Shower Booth because it serves the purpose of confining the air circulation to the booth only.

Any new streams of layer entering or leaving the booth will increase the chance of contamination.

Also, the turbulence of particles gives rise to contamination and therefore, a uniform motion must be maintained.

The sealant maintains the positive pressure by confining all the air in the cavity of the booth. Any leaks or loss of air can result in poor function.

It also prevents cross-contamination and mixing which is beneficial in not only avoiding contamination but also infectious diseases and harmful chemicals.

Is UV Sterilization Useful in your Air Shower Booth?

UV sterilization can be helpful in an Air Shower Booth when complete sterilization is required.

When working with the applications like hospitals, pathology laboratories, and pharmaceutical clean rooms, there is a high chance of nosocomial infections.

Which can not only spread to the staff working in the environment but also to the people outside the hospital and working facility.

Therefore complete sterilization is necessary to make a sterile room.

When UV radiation falls on the DNA of the microorganisms, it disrupts the chromatin material, attacking the nucleic acids thus destroying the nucleus. This leads to the death of the microorganism as the DNA is completely lost.

Without the DNA, there is no survival and replication thus complete removal of organisms like fungi, bacteria, and viruses.
