Air Shower: Everything You Need to Know about Cleanroom Contamination Control, Performance, and Purchase

Even a single airborne particle can lead to batch rejection, product recalls, or audit failure in regulated industries.

An air shower for a cleanroom is not just an entry system — it is your first line of defence against contamination. Explore our air shower solutions to understand how the right system can improve your cleanroom performance.

A cleanroom air shower system ensures that personnel and materials are decontaminated before entering controlled environments, maintaining compliance with ISO 14644 standards.

Air Shower Working Principle and How It Functions

Understanding the air shower working principle is essential for selecting the right system for your cleanroom environment.

An air shower refers to an independent chamber which is placed at the entrances of the cleanrooms and functions on the principle of high-speed jet streams with the help of HEPA-filtered air in blowing away contaminants that have adhered to the surface material or clothes.

It begins with the entry of the individual into the chamber, upon which the interlocked doors will shut automatically. The air streams, at a speed of about 20 to 25 metres per second, will hit the body of the individual from different sides. The contaminants thus released from the body get blown away in the room by the return air vent and get filtered using HEPA and ULPA filters.

Thus, the entire process keeps the contaminants from entering the cleanroom, keeping the cleanliness standard of ISO 5, 6 or 7 intact.

These classifications are defined under ISO 14644, the global standard for cleanroom performance and contamination control.

The Importance of Air Showers in Modern Industries

Modern industries have been found unable to endure any contamination, as this would bring about a number of negative consequences on their production processes. For example, if there is contamination in the production process of pharmaceutical products, they will be considered unfit for use. Contamination in the production process of semiconductors could cause circuit failure.

From the above discussion, it is clear that the importance of air showers is becoming increasingly significant in modern industries.

For example, pharmaceutical cleanrooms use air showers to maintain sterile production, while semiconductor industries rely on them to prevent micro-particle damage to circuits.

Air Shower Specifications You Must Evaluate Before Buying

One must not base one’s choice when purchasing an air shower only on cost factors. Performance of an air shower depends largely on many important technical specifications.

Material quality in manufacturing is an important aspect. Stainless steel air showers are preferred for use in pharmaceutical and sterilisation departments. Industrial air showers can be produced using powder coating.

Air velocity is yet another critical technical specification. An effective air shower must feature velocity rate of at least 20-25 metres per second.

The HEPA filter efficiency must be capable of filtering 99.97% of particles with a diameter of 0.3 microns. For highly sensitive applications in clean rooms, ULPA filters may be used.

The design of nozzle placement greatly affects cleaning efficiency. Effective nozzles are those that feature adjustable stainless steel nozzles placed all over one’s body.

An interlocking door system helps prevent contamination since one door cannot open without the other being closed first.

Control systems include basic timers to more complex PLC control touch panel systems.

Categories of Air Shower Systems

There are several types depending on the purpose. Single air showers are used where there is less traffic in the cleanrooms, whereas multiple air showers are used for high traffic.

Material air showers are for carrying material into the cleanroom while maintaining its cleanliness, while tunnel air showers are best suited for processes such as the assembly of electronics.

It depends on the usage frequency and cleanroom category.

Air Shower vs Other Contamination Control Methods

Air showers are often compared with other contamination control solutions, but their functionality is unique.

Sticky mats only capture particles from footwear, while gowning rooms rely heavily on human discipline. Air showers provide automated, consistent contamination removal, making them a more reliable solution.

How to Choose the Best Air Shower?

There are several important aspects one needs to consider while selecting the best air shower, besides costs only.

The cleanroom class will determine the quality of filtration and airflow that we will achieve. The higher cleanroom classes will require better filters and airflow rates.

Entry volume will determine the size of the room and its capacity. Bigger entry volumes will require bigger capacities.

Compatibility of materials will also be of great importance in order to achieve material compatibility. For sterile applications, stainless steel is essential; however, for other types of industries, other materials could be applied.

Automation will also play an essential role.

Why Most Air Showers Fail 

Many air shower for cleanroom installations fail due to poor engineering design and lack of 

proper airflow planning.

Poor airflow design leads to uneven cleaning performance, leaving contaminants on critical areas.

Dead zones inside the chamber prevent proper air circulation, resulting in incomplete particle removal.

Weak filtration systems reduce air purity, allowing micro-contaminants to re-enter the cleanroom.

How Do We Do That?

We utilize CFD air flow simulation technology for optimized air flow designs that provide total coverage within the room.

Strategically placed nozzles guarantee that every surface area of the body comes into contact with high velocity air.

Our Air Shower Systems will be customized for your site design needs and in accordance with cleanroom standards.
