The difference between an air shower and a fog shower

There are differences between air showers and fog showers in the following aspects:
Working principle
Air shower: Air is drawn into the sealed chamber by the fan after passing through the primary and medium efficiency filter groups, and then discharged into the static pressure chamber. It then enters the working area through the high-efficiency filter. The clean air can be preheated by the electric heater and finally discharged into the air shower chamber through the air shower nozzle. The dust particles on the surface of people or objects are blown away by the high-speed clean airflow.
Fog shower room: Through the atomization device, specific liquids are atomized into tiny droplets. The droplets cover and wrap the dust-like pollutants on the work clothes, causing them to condense into large particles. At the same time, the high-speed airflow blown out by the nozzle accelerates the fall of the particles, completing the powder encapsulation and removal process.
Structural characteristics
Air shower room: It is mainly composed of a top box, inner and outer doors, side box, base, fan, electric heater, high-efficiency filter, nozzle, return air outlet, pre-filter electrical control components, etc.
Fog shower room: It is usually designed in a modular way, with the material mostly being all stainless steel SUS304. It is equipped with airtight gaskets and electromagnetic interlock doors and is furnished with atomization devices, photoelectric control devices, HEPA air filtration ventilation circulation systems, and programmable PLC control systems.
Application scenarios
Air shower: Widely used in clean rooms in various industrial and scientific research fields such as electronics, machinery, medicine, food, and bioengineering, it is used for purification before personnel and goods enter the clean area to reduce the introduction of dust.
Fog shower room: Mainly applied in the pharmaceutical industry, chemical industry, laboratories, and other places with high requirements for environmental cleanliness, it is specifically used to treat dust-like highly active particulate pollutants on work clothes.
Purification effect
Air shower: It can effectively remove dust particles from the surfaces of people and goods, but it may not be able to completely remove closely adhering tiny particles.
Fog shower room: For specific dust-like highly active particle pollutants, through atomization wrapping and airflow assistance, it can more thoroughly remove the pollutants on work clothes and prevent their spread.
Operation and Maintenance
Air shower room: The operation is relatively simple. It mainly starts the air shower program automatically or manually after people or goods enter. In terms of maintenance, it is necessary to regularly clean the inner and outer surfaces, replace the filters, and inspect the fan and other components.
Fog shower room: The operation needs to set parameters such as time, cycle, and spray time according to specific procedures. During maintenance, in addition to inspecting the electrical and mechanical components, it is also necessary to pay attention to the status of the atomization device to ensure its normal atomization. At the same time, it is important to clean the interior of the atomization chamber to prevent liquid residue and bacterial growth.
