The double-person double-blowing air shower adopts an extended cavity, which can accommodate two people to shower at the same time. Aili Industrial configures the cavity size, nozzle layout, door structure and filtration system according to the personnel traffic volume, entry sequence, station mode and induction control requirements, so that the air shower can maintain traffic efficiency during shift peaks or double traffic scenarios.

The length and width of the inner cavity of a double air shower need to accommodate two people standing side by side or front to back. The station position affects blowing and shower coverage and traffic efficiency, and should be confirmed in conjunction with the personnel traffic process during model selection.
If two people stand side by side, the width of the cavity should ensure that each person has enough room to turn around; if they stand front to back, the length of the cavity needs to be increased accordingly. Air shower room classification and structural form can be viewed Air showers understand different models.
The air shower room is equipped with nozzles on both sides to spray the surface of people's clothing from different angles. When using it with two people, you should confirm whether the nozzle coverage can cover the standing positions of two people at the same time to avoid one person blocking the shower airflow of the other person.
The number, angle and air outlet speed of the nozzles can be configured according to the cavity size and blowing requirements. After entering, personnel should turn their bodies in the shower area so that all surfaces can be covered by the airflow. For specific air volume calculations, please refer to How to convert face wind speed and air volume?。
After the air passes through the primary filter and high-efficiency filter, it is sent to the nozzle by the fan, blows the surface of the personnel, and then returns to the front end of the filtration system through the return air outlet to form a cycle.
Return air filtration needs to be matched with the nozzle layout, air duct and fan working point. The air volume and return air area of the double air shower room increase accordingly, and you should check whether the fan working point meets the requirements. The return air outlet should be kept clear to prevent obstruction by clothing or objects from affecting circulation.
Double air showers are usually equipped with induction control, which automatically starts the shower after people enter. The sensing range and start-up logic need to match the two-person positioning to prevent one person from starting the timing before the other person is in position.
The front and rear doors are interlocked to prevent the doors on both sides from being opened at the same time and causing an airflow short circuit. The blowing time can be set according to management requirements, and the blowing cycle may need to be adjusted when used by two people. For specific control logic, please refer to Learn about the basic configuration of a single-person double-blowing air shower .
The air shower box can be made of stainless steel or steel plate with plastic spray material, which shall be confirmed according to the use environment, cleaning requirements and appearance requirements. Stainless steel is corrosion-resistant and easy to clean, making it suitable for places with high surface cleaning requirements.
The inner wall should be smooth, not prone to dust accumulation, and easy to wipe daily. The double air shower has a long cavity, and the corner treatment and lighting arrangement should be convenient for inspection and cleaning.
After people enter the air shower room, the induction device triggers the fan to start. After primary filtration, the air is sent to the high-efficiency filter by the fan, and then blown to the surface of the personnel through the nozzles on both sides. The air carrying particles returns to the front end of the filtration system through the return air outlet, forming a cycle.
Personnel enters → Induction start → Primary filter → Fan air supply → High efficiency filter → Double-sided nozzle blowing → Return air circulation → End of blowing → Unlock the exit door
When two people are showering at the same time, their positions and clothing may block local airflow from each other. The shower effect should be confirmed based on the actual traffic flow and standing position.

The air shower is mainly used for surface blowing of personnel and clean area entrance management. It does not replace the dressing process, material purification and the air purification system of the clean room itself. When infectious or hazardous materials are involved, equipment should be selected based on the risk.
The double air shower room is suitable for places where there are shift peaks or where two people pass through at the same time. When selecting a model, you should confirm the number of people passing through per hour, whether two people enter at the same time, and whether they stand front to back or side by side.
Two people standing side by side or in front of each other will affect the shower coverage. It should be confirmed that the nozzle layout can cover the standing positions of two people at the same time to prevent one person from blocking the shower airflow of another person.
The sensing range should cover the two-person standing area, and the activation logic should match the traffic flow. Access control interlocking and shower time need to be adjusted according to the double passage efficiency.
The air shower has a large external dimension, so the door opening size, floor flatness and surrounding passages should be checked before installation. The return air vent and filter require regular maintenance, and maintenance channels should be reserved around them. Insufficient maintenance channels will increase subsequent expenditures. This is reflected in what later expenses will be increased due to insufficient maintenance channels . There is a more detailed analysis of
Clean the inner wall, nozzles and return air outlets of the air shower in accordance with management requirements to avoid dust accumulation that affects the shower effect. Pay attention to protecting the nozzle angle and filter system seal when cleaning.
Maintain the primary filter according to the frequency of use and environment, and determine the maintenance needs of the high-efficiency filter based on pressure difference, wind speed and filter status. After replacement, the installation seal and related performance should be rechecked. To judge the initial resistance and final resistance, please refer to What are the initial resistance and final resistance used to judge? , sealing inspection can refer to What should be checked when cleaning equipment is accepted?。
Regularly check the access control interlock, sensor device and shower timing function to ensure that the two-person passage process is normal.

The double air shower has an elongated cavity that can accommodate two people showering at the same time, making it suitable for shift rush hours or double-passage scenarios. Single-person air showers are suitable for places with small traffic volume.
The two people's standing positions and clothing may block local airflow. The nozzle layout and positioning method should be confirmed when selecting the model, and the blowing effect should be verified according to the agreed conditions after installation.
The blowing time is usually adjustable, and the specific range is confirmed according to the control plan. When used by two people, the setting value can be adjusted according to traffic efficiency.
The access control interlock is a configuration that prevents the doors on both sides from being opened at the same time. It should be used according to management requirements and is not recommended to be closed. The specific logic is confirmed in the control scheme.
It should be judged based on the pressure difference, wind speed and filter status. Recheck sealing and related performance after replacement.
Clarifying the amount of personnel traffic, traffic methods, installation space, shower requirements and material requirements will help determine the double air shower configuration suitable for the clean room entrance.
