The difference between a fog shower room and an air shower room

There are many differences between fog showers and air showers in terms of function, application scenarios, working principles, and structural design. The following is a detailed introduction:
Functional characteristics
Air shower: Its main function is to use high-speed clean airflow to blow away dust particles on the surfaces of people and goods, reducing the amount of dust brought into the clean area. At the same time, it serves as an airlock to prevent unclean air from entering the clean area and maintain a stable air pressure inside the clean room.
Fog shower room: In addition to the air-blowing function of the air shower room, it also has the water mist-blowing function. Through a high-pressure pump, water is sprayed in a fine mist form to moisten the dust adhering to the work clothes, preventing the dust from flying and condensing it into large particles that fall and settle.
Application scenarios
Air shower: Widely used in fields with high environmental cleanliness requirements, such as food, medicine, bioengineering, microelectronics, and precision instrument manufacturing, it purifies and pretreats before personnel or goods enter the clean area.
Fog shower room: Mainly applied in the pharmaceutical, biological laboratory, chemical, and other industries, it is used in places involving "toxic dust" or highly active drug components. It is used to deal with the dust adsorbed on the work clothes of staff when they leave the clean room, preventing pollution sources from being carried out and protecting the external environment and staff from contamination.
Working principle
Air shower: The polluted air after the air shower is purified by the air filter, then passes through the static pressure chamber, and finally is blown at high speed from the nozzles on the top, left, and right sides of the air shower to all parts of the human body, blowing off the dust particles and then passes through the high-efficiency filter for filtration and circulation.
Fog shower room: Firstly, a low-flow wet mist is formed through the fog shower system to coat the dust particles on the work clothes and condense them into large particles. Then, the high-speed airflow generated by the air shower function is used to make the large particle materials fall and settle on the surface of the filter or in the dirt collection tray.
Structural design
Air shower room: It is usually composed of a box body, door, filter, supply fan, distribution box, nozzle, and other components. The box body materials have various options such as stainless steel, steel plate, color steel plate, etc. The nozzles are generally rotatable and can blow water on people or goods from all directions.
Equipment air shower room
Fog shower room: The basic components include a fog shower system, air shower system, waste liquid collection, exhaust function, etc. The fog spray nozzles and lighting fixtures are located at the top, while the air spray nozzles are on both sides of the walls. Behind the wall panels, there are air outlets and return ducts. The bottom is generally designed with perforated holes and is equipped with a water collection trough and an outlet pipe for collecting waste liquid.
Equipment fog shower room
Control mode
Air shower room: It mostly adopts PLC intelligent control means. The operation status of the air shower, the interlocking status of the two doors, the progress of the air shower cycle the delayed opening status, etc. are displayed on the LED screen on the control panel. It can realize functions such as automatic sensing air showers and timed air showers.
Fog shower room: It is also controlled by PLC and touch screen, allowing for free setting of atomization spray time, fan blowing time waiting time, etc. It is equipped with three levels of permission, facilitating operation by managers at all levels. At the same time, it has functions such as alarm information display, three-color light, and buzzer auxiliary indication.
