Aili Industrial Three-person Double-Blow Air Shower

Equipped with extended double-side blowing and shower equipment for three-person group traffic

The three-person double-blowing air shower adopts an elongated cavity that can accommodate three people for showering at the same time or in groups. Aili Industrial configures the cavity size, nozzle layout, door structure and filtration system based on the number of people changing shifts, entrance movement lines, grouping methods and induction control requirements, so that the air shower room maintains traffic efficiency and blowing coverage in multi-person shift scenarios.

Features

Extended cavity and three-person position

The length of the inner cavity of a three-person air shower needs to accommodate three people standing. There are usually two types of positioning methods: front-to-back arrangement and grouping arrangement. Different positioning methods affect the length, width and blowing coverage of the cavity.

If three people stand front to back, the length of the cavity needs to be increased accordingly, and the blowing nozzle should cover the front, middle and rear positions. If three people stand side by side, the width of the cavity needs to be enough for three people to turn around at the same time. Air shower room classification and structural form can be viewed Air showers understand different models.

Blowing shower coverage at front, middle and rear positions

When used by three people, the nozzle layout needs to cover the front, middle and rear positions. People in the front row may block part of the airflow for people in the back row. When selecting a model, you should confirm whether the number and angle of the nozzles can cover three positions at the same time.

If group showering is used, three people can be divided into two groups and showered one after another to reduce mutual obstruction. The specific grouping logic should match the traffic flow and shower time. For the conversion of face wind speed and air volume, please refer to How to convert face wind speed and air volume? learn.

Filter circulation and return air structure

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.

The air volume and return air area of ​​the three-person air shower room increase accordingly, and it should be checked 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. Return air filtration needs to be matched with the nozzle layout, air duct and fan working point.

Sensing layout and group access logic

Three-person air showers are usually equipped with induction control, which automatically starts the shower after personnel enter. The sensing range needs to cover the three-person standing area, and the activation logic should match the group traffic method.

If group showering is used, the sensing system can identify the number of people entering or grouping areas and start showering according to the corresponding logic. 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. For control logic, please refer to Double double blow air shower room is suitable for multi-passage configuration.

Box material and surface treatment

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 three-person air shower has a long cavity, and the corner treatment and lighting arrangement should be convenient for inspection and cleaning.

Working principle

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 three people are showering at the same time, their positions and clothing may block local airflow from each other. The blowing effect should be confirmed based on the actual traffic flow and standing position, and group blowing should be used if necessary.

Technical parameters and configuration

The performance of the air shower needs to be confirmed through complete machine testing and cannot be judged solely based on filter efficiency. For the difference between filter efficiency and work area cleanliness, please refer to What is the difference between cleanliness level and filtration efficiency?。

Application scenarios

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.

Key points for air shower selection and installation

Confirm the number of people changing shifts and the way of passage

The three-person air shower is suitable for shift peak times or team traffic scenarios. When selecting a model, you should confirm the number of people passing through per hour, whether three people can enter at the same time, whether they can be showered in groups, and whether the standing position is front to back or side by side.

Check the three-person positioning and shower coverage

Three people standing in front of each other or side by side will affect the shower coverage. It should be confirmed whether the nozzle layout can cover the front, middle and rear positions to prevent people in the front row from blocking the shower airflow of those in the back row.

Confirm sensor layout and grouping logic

The sensing range should cover the three-person standing area, and the activation logic should match the group traffic method. If group blowing is used, the control plan and blowing cycle should be confirmed.

Reserve space for installation and maintenance

The three-person air shower has a longer appearance. Before installation, the door opening size, floor flatness and surrounding passages 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

Routine maintenance

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 access control interlocks, induction devices and shower timing functions to ensure that the three-person access process is normal.
