As an airlock, how can the air shower room prevent unpurified air from entering the clean area?

In modern clean workshops and assembly clean rooms, the air shower room plays a vital role. It is not only a purification device that blows away the dust attached to the surface of people and objects in the clean workshop, but also a key barrier as an airlock to strictly prevent unpurified air from entering the clean area.
The design of the air shower room cleverly combines the two technologies of air purification and airflow control. First of all, the air shower room is equipped with a high-efficiency filtration system. These filtration systems are usually composed of primary, medium and high-efficiency filters, which filter layer by layer to ensure that the air blown out reaches a very high degree of cleanliness. When people or objects enter the air shower room, the high-efficiency filtration system starts, blows out high-speed clean airflow, and comprehensively showers the surface of people or objects, effectively removing attached dust, microorganisms and other pollutants.
However, the role of the air shower room is far more than that. As an airlock, the two doors (entry door and exit door) of the air shower room adopt an electronic interlocking mechanism. This means that when the entry door is opened, the exit door will automatically lock to prevent people or objects that have not been purified by blowing and showering from entering the clean area directly; vice versa. This design ensures that the air shower room always maintains a relatively closed space, avoiding the mixing of unpurified air and clean area air.
During the air shower process, the high-speed clean airflow not only blows away the dust on the surface of people or objects, but also forms a positive pressure environment. This positive pressure environment is relative to the clean area, which effectively prevents the unpurified air from the outside from penetrating into the clean area through gaps or door cracks. At the same time, the air outlet design of the air shower room also fully considers the guidance of the airflow, ensuring that the airflow after showering can be quickly discharged from the air shower room and will not flow back to the clean area.
In addition, the air shower room is also equipped with an intelligent control system, which can adjust the parameters such as shower time and wind speed according to the actual needs of the clean workshop to achieve the best purification effect. At the same time, the shell of the air shower room is usually made of corrosion-resistant and easy-to-clean materials such as stainless steel to ensure that the equipment itself will not become a source of pollution.
In summary, as an airlock, the air shower room effectively prevents unpurified air from entering the clean area through multiple protection measures such as its high-efficiency filtration system, electronic interlocking mechanism, positive pressure environment and intelligent control system. This function is of vital importance to maintaining the environmental quality of clean workshops, ensuring product quality and personnel health. Therefore, in the design and operation of clean workshops and assembly clean rooms, the selection, installation and maintenance of air shower rooms should be given full attention and concern.
