The Working Principle of The Air Shower Room in The Clean Room

The clean rooms play a central role in the quality of products and brand reputation in the chip manufacturing industry, pharmaceutical manufacturing industry, cosmetics processing industry and food manufacturing industry. Clean rooms are indispensable whether it comes to the prevention of the influence of particulate matter on the chip yields or the microbial contamination of pharmaceuticals and food.

An air shower is a crucial checkpoint for all processes entering a clean room. More than just a piece of equipment, it serves as a protective mechanism, ensuring that surface dust and contaminants are removed to the greatest extent possible before people and objects enter the cleanroom, truly keeping risks out.

We have been in the industry of clean rooms for 17 years and have seen more than 1000 client projects being designed to be implemented. We have arrived at the conclusion that a good air shower is not merely air supply and filtration but a holistic approach to the matter integrating technology with experience.

Why are air showers so important?

When planning their clean room projects, many clients ask us, "Is an air shower optional?" In fact, in most high-standard cleanrooms, air showers are a must-have. The reason is simple:

They are really efficient in eliminating contaminants on surfaces, people, and objects. Particles or microorganisms could be present in clothing, hair, and shoes and cause serious problems when they get to the cleanroom.

They stabilize clean room classifications. Cleanroom operation relies on continuous control, and air showers, acting as entry points, prevent frequent breaches of cleanliness levels.

They meet international standards. In industries such as chips, pharmaceuticals, and food, the use of air showers is no longer just an option; it's the standard.

How an Air Shower Works

1. Air Filtration - Intercepting Pollution at the Source

Air entering the air shower first passes through a primary filter to remove large particles. A high-pressure fan then forces the air into a static pressure chamber, where it passes through a high-efficiency particulate air (HEPA) filter for deep purification, ultimately creating highly clean air.

2. High-Velocity Airflow - Thoroughly Removes Debris

Clean air is evenly sprayed at high speed onto surfaces such as people and objects through a rotating nozzle. This airflow quickly removes dust from clothing and tools, completing the cleaning process in 30-60 seconds.

3. Circulating Purification - Continuous Cleaning

Dislodged particles are recirculated through the filter in the return airflow, achieving internal purification and ensuring consistently clean air inside the air shower.

4. Automatic Control - Smarter Operation

Air showers are typically equipped with infrared sensors and timers. The airflow automatically activates upon entry, preventing operator error.

5. Double-Door Interlocking – Safe "Airlock" Function

The air shower's double doors feature an electronic interlocking design. The rear door won't open until the shower is complete, effectively preventing unpurified air from entering the clean area.

The Value of Air Showers

• An air shower is not a single device. It is more entwined with the grade and functional effectiveness of a cleanroom.

• To the chip manufacturers, it minimizes ingress of particulate matter and guarantees chip yield.

• In the case of pharmaceutical companies, it limits the chances of microbial contamination and adherence to the GMP regulations.

• In the case of the food and cosmetics industry, it safeguards the environment under which the food is produced and also secures the safety of the consumer.

• Meaning, an air shower is a long-term investment that helps not only to increase the level of cleanliness but also to protect the quality of products and brand image.
