Air showers play a crucial role in maintaining the integrity of clean room systems, which are vital in industries such as pharmaceuticals, biotechnology, and semiconductor manufacturing. Strategically installed at the entry and exit points of clean rooms or other controlled environments, air showers serve as a preliminary contamination control barrier.

These specialized chambers are equipped with high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters, which are capable of capturing and removing a high percentage of airborne particles, including dust, bacteria, and other contaminants. As personnel pass through the air shower, a powerful stream of purified air is directed at them from multiple angles. This forced airflow dislodges and removes loose contaminants from their clothing and exposed skin, effectively reducing the bioburden entering the clean room.

By minimizing the introduction of particulates and microorganisms, air showers contribute significantly to enhancing the overall cleanliness and sterility of the clean room environment. This not only helps in preventing product defects caused by contamination but also promotes a higher standard of hygiene, ultimately leading to improved yields and product quality. Thus, air showers are an indispensable element of protocols aimed at ensuring compliance with stringent clean room standards.

What is an Air Shower?

Air showers are specialized pass-through chambers strategically installed at every entrance and exit point of a clean room. These systems are integral to contamination control, effectively removing particles such as dust and bacteria that personnel may carry when entering the clean room environment. The operation of an air shower involves the use of high-pressure turbulent air jets, which can propel air at speeds ranging from 3,000 to 7,000 feet per minute. This rapid airflow is designed to dislodge and eliminate contaminants from individuals before they access the clean room, employing a reverse airflow or suction mechanism to enhance the effectiveness of the cleaning process.

Clean rooms help in the removal of tiny particles and make the atmosphere free from any contamination to ensure hygienic manufacturing process. Clean rooms are commonly used in industries like manufacturing, pharmaceuticals, medical devices, biotech, electronics and more. Cleanrooms use air showers to adhere to strict guidelines and remove all the contamination.

The presence of contaminants can significantly risk the hygiene and reliability of cleanroom systems. Particles can easily accompany personnel or the equipment and materials they transport, which highlights the necessity for air showers at all entry and exit points of clean room facilities. By implementing air showers, organizations can better safeguard their clean room environments, maintain compliance with strict industry regulations, and ensure optimal operational outcomes by minimizing contamination risks.

Benefits of Air Showers

The entire clean room system is essential to prevent contamination. But, air showers indeed is an essential part of the system. Air showers help in the prevention of contamination and impacts positively on the quality of the products and equipment that are being manufactured in the clean room.

Not only this, air showers help in reducing the need for continuous maintenance of the classroom as the risk of contamination will be subdued. Installing an air shower clean room will help remove contamination at the very entrance of every personnel. This will improve the performance and life of HEPA and ULPA filters. Other than this, air shower systems will also enhance the efficiency of the HEPA filters by putting less stress on them.

Types of Air Showers in India

Following are some of the types of air shower systems available in India:

Roll-up Door Air Shower Tunnel
Double Door Air shower (Sliding or Pull type manual)
Air Shower Tunnel – Walk through with Single Door
Standard Single Door Air Shower for 3-6-9 persons (Door size 800 mm approx x 6 ft Approx depth)

Let’s now understand the types of air shower clean room systems in detail below:

Roll-up-Door Air shower tunnel

You can move upto 15-20 Workers or staff at a time. Man and Material movement can take place through this. We have added sanitizer mist nozzles with pumps as optional which means there is double action which is taking place. Bacteria removal action takes place with high pressure air jets using HEPA H14 filters and side by side Sanitization by using WHO approved industrial sanitizer alcohol and cetrimide based. This feature is an optional . Size : Upto 3000 MM Door Width x 2500 Height X 2500 Depth

Advantage of Roll up Door Air shower:

Heavy movement of workers / staff
Man and material movement can be done simultaneously
Direct Floor mounted
Fully automatic , sensor operated

Double Door Air shower (Sliding or Pull type manual)

This design is also suitable for heavy traffic and door design is sliding with sensor or pull type manual with handle . Here the space is needed on the sides for the door movement. This is also floor mounted or can be raised flooring. Floor mounted can be used for man and material movement both. Door size: 1500 mm x Depth of ( 2000 X 2000 MM).

Air Shower Tunnel – Walk through with Single Door

Keep moving through the tunnel 2 to 3 persons at a time and next 2-3 persons can enter after the first lot is out of the tunnel. This is used where space is constrained on the width wise. You cannot move Material in this tunnel as the base is raised flooring with perforated or chequered plate. Size: 1000 mm (with 800 mm door) x 12 ft long.

Standard Single Door Air Shower for 3-6-9 persons. (Door size 800 mm approx. x 6 ft approx. depth)

Conventional design Air shower for low traffic of workers or no requirement of material movement.

How to Choose the Best Air Shower?

While selecting the best air shower system for your clean room, you should consider the factors mentioned below:

The air shower shell should be made of stainless steel or painted steel
The air shower system should be modular, which means it should come with an easy configuration, shipment. Not only this, it should be easy to assemble as well
The blower fans used in the air shower clean room system should supply high velocity and volume of air, which will help in keeping the clean room free of contamination
The system should come with pre-filters and HEPA filters to ensure effective filtration system

The air shower system should include multiple air nozzles.
