Length, partition and function customization |
The length of the air shower channel determines the number of people accommodated and the traffic rhythm at the same time. If the channel is too short, it is easy to queue up during peak hours; if the channel is too long, it will occupy the entrance space and may increase the shower time. When selecting, the length of the channel should be determined based on the peak number of people, allowed waiting time and shower cycle.
The channel can be equipped with multiple shower sections along the traffic direction, and people can pass through them in order. Please refer to the specific length and segmentation method. Air showers understand the basic structure.
When multiple people pass through, the channel can be divided into multiple shower zones, each zone equipped with independent nozzles and sensor controls. After people enter different partitions, the system starts blowing and showering according to the partition, reducing mutual obstruction and waiting time.
Zoning control requires corresponding air ducts, nozzles and control logic support. If the channel is long, the plan of blowing the front and rear partitions sequentially or at the same time can be evaluated. For control methods, please refer to Double double hair shower room and The three-person double-blow air shower room understands the logic of multiple people passing.
The air shower channel is equipped with nozzles on both sides to spray the surface of the clothes of people passing by from different angles. The nozzles are distributed along the length of the channel so that personnel are continuously covered by blowing water from the entrance to the exit.
The number, spacing and angle of the nozzles can be configured according to the channel length and blowing requirements. When people pass by, they should maintain an appropriate speed so that all surfaces can be covered by the airflow. Please refer to the air volume conversion 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.
When the passage is long, the return air layout needs to be checked together with the nozzle distribution and fan operating points. The return air outlets can be evenly arranged along the channel to avoid insufficient air volume at the end. The return air outlet should be kept clear to prevent obstruction by clothing or objects from affecting circulation.
The entrance and exit of the air shower channel can be equipped with automatic doors, interlocking doors or sensor doors, which must be confirmed according to the personnel flow process and management requirements. The front and rear doors interlock to prevent the doors on both sides from opening simultaneously and causing an airflow short circuit.
When multiple people pass, the door opening logic needs to match the partition shower and traffic rhythm. If the passage is long, a buffer zone or segmented door can be set up in the middle to reduce the interaction between people in the front and rear.
The air shower channel 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. When aisles are long, corner treatments and lighting arrangements should facilitate inspection and cleaning.
After people enter the air shower channel from the entrance, the induction device triggers the fan in the corresponding zone 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 → Zoned nozzle shower → Return air circulation → End of shower → Unlock the exit door
When multiple people pass by at the same time, their positions and clothing may block local airflow. The shower effect should be confirmed based on the actual traffic flow and channel zoning.

The air shower channel is mainly used for surface showering 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 length of the air shower channel and the number of partitions should match the peak number of people, allowed waiting time and shower cycle. When selecting a model, first record the peak number of people changing shifts and entrance movement lines, and then determine the channel length and zoning method.
Zoned blowing can reduce mutual obstruction, but it requires corresponding air ducts, nozzles and control logic. It should be confirmed that each partition can cover the standing position to avoid one person blocking another person's shower airflow.
The form of entrance and exit doors should match the flow of traffic. The front and rear door interlocking and partition door logic need to be confirmed in the control plan to ensure traffic efficiency and blowing effect.
The air shower channel has a long overall dimension. Before installation, the door opening size, ground flatness and surrounding channels should be checked. 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 of the air shower channel, nozzles and return air outlets 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 door interlocks, sensing devices and partitioned shower functions to ensure normal flow of multiple people.
