What is the role of air showers in clean rooms?

In modern industry and scientific research, the construction and use of clean rooms are crucial, especially in industries with extremely high environmental requirements such as pharmaceuticals, Electronics and biotechnology. As an important part of clean rooms, the role of air showers cannot be ignored. This article will analyze the definition of clean rooms, environmental control standards, the specific role of air showers and how to use them, to help readers deeply understand the importance of air showers in clean rooms.

I. What is A Clean Room?

A clean room is a special environment designed to control the effects of airborne particles, pollutants, bacteria, etc. on specific processes or products. Its main feature is that the concentration of suspended particles in the air is extremely low to ensure the accuracy and safety of production processes and experiments. Clean rooms usually use high-efficiency filtration systems, strict temperature and humidity control and airflow organization to maintain the required cleanliness level.

II. Clean room environmental control standards

The environmental control standards for clean rooms are usually based on international standards, such as the ISO 14644 series of standards. These standards specify parameters such as the number of particles, microbial limits, and temperature and humidity ranges in clean rooms. For example, iso5 cleanrooms require that the number of particles in each cubic meter of air must not exceed 3,520 (≥0.5μm particle size), while biological contamination control requires regular air monitoring and surface sampling. These standards provide a basic basis for the design, construction and operation of cleanrooms.

III. The role of air showers

The main role of air showers in cleanrooms can be summarized as follows:

1. Dust removal and disinfection

The air showers effectively remove dust, particles and microorganisms on the surface of people or objects through high-efficiency air filtration and powerful fans. Before entering the cleanroom, the air shower spray provided by the air shower can significantly reduce the source of pollution and reduce the concentration of particles in the cleanroom.

2. Clean transition between people and objects

As a transfer station for people or objects to enter the cleanroom, the air shower can ensure that all entrants or goods are strictly cleaned before entering the clean environment. This design avoids the direct impact of external pollutants on the cleanroom and ensures the stability and reliability of the cleanroom.

3. Improve the cleanliness level

Through an effective air shower device, the air shower can achieve efficient dust removal and disinfection in a short time, ensuring that the cleanliness level in the clean room meets the design requirements, especially in places where there is frequent personnel flow, the role of the air shower is particularly significant.

4. Standardize the operation process

The use of the air shower can standardize the entry and exit process of personnel and goods, and reduce the impact of disorderly operations on the clean room environment. By setting up an air shower room, enterprises can establish standardized entry and exit procedures in operation and improve the overall management level.

IV. How to use the air shower

The use of the air shower usually includes the following steps:

1. Preparation before entering

Before entering the air shower room, the user must ensure that the clean room clothing, including dust-proof clothing, gloves and masks, etc., is worn.

2. Open the air shower door

The user opens the door of the air shower and enters the room.

3. Start the air shower device

According to the design of the air shower, the user can start the air shower device through a button or automatic sensor for air shower treatment. The air shower time is generally set to 30 seconds to 1 minute, and the specific time can be adjusted according to actual needs.

4. Exit after air shower

After the air shower treatment is completed, the user can open the door on the other side and Enter the clean room. During this process, direct contact with the external environment should be avoided to reduce the risk of contamination.

5. Regular maintenance and monitoring

The maintenance and monitoring of the air shower room are equally important. The fan, filter and equipment operation should be checked regularly to ensure that they operate in the best condition.

The air shower plays an irreplaceable role in the clean room. Through efficient dust removal and disinfection, clean transition of personnel and objects, improved cleanliness level and standardized Operation procedures, the air shower significantly improves the environmental control effect of the clean room. The correct use and maintenance of the air shower is an important guarantee to ensure the stable operation of the clean room, which is of great significance to achieving high-standard production and scientific research goals.
