In the clean area, under dynamic conditions, the biggest source of bacteria and dust is the operator. Before the operator enters the clean area, the dust particles attached to the surface of his clothes are blown with clean air, which can reduce the occurrence of pollution in a certain process.
The air shower room is a necessary purification equipment for personnel to enter the clean area dust-free workshop. It is highly versatile and can be used with all clean areas and clean workshops. When the staff enters the workshop, they must pass through this equipment and use strong and clean air to spray people from all directions by a rota-table nozzle to effectively and quickly remove dust, hair, hair dandruff and other debris attached to the clothes. It can reduce the pollution problems caused by people entering and leaving the clean area.
The two doors of the air shower room are electronically interlocked, which can also serve as an airlock to prevent external pollution and unpurified air from entering the clean area.
Regarding the length and number of air shower rooms, multiple factors need to be considered to reduce the waiting time of personnel and the vacancy time of air shower rooms:
When the number of people in the workshop is about 20, a single-person air shower can be selected, so that more than 20 people can pass through in about 10 minutes.
When the number of people in the workshop is about 50-150, it is necessary to consider the hand washing and disinfection facilities in the workshop. Here we take 100 people, the total hand washing and disinfection time for one person is 1min (hand washing 15s + soaking disinfection 30s + rinsing and drying hands 15s) and the air shower time is 30s as an example. When there are 8 hand washing positions, the number of people who can enter the air shower room per minute is 8. At this time, 2 double-person air shower rooms can meet the demand, and it takes 12.5min for all personnel to pass through; when there are 10 hand washing positions, the number of people who can enter the air shower room per minute is 10. At this time, 2 three-person air shower rooms can be selected (reducing the waiting time for personnel), and it takes 10min for all personnel to pass through, or 2 two-person air shower rooms (effective use of air shower rooms), and the time for all personnel to pass through is 12.5min.
If the number of people in the workshop is more than 300, in addition to the small room air shower room, we can also consider choosing a channel air shower.
Please do not place the air shower room at the high-speed dust source and earthquake source. Please do not wipe the cabinet with volatile oil, thinner, corrosive solvent, etc. to avoid damaging the paint layer or causing discoloration. The following places should not be used: low temperature, high temperature, high humidity, condensation, dust, and places with oil smoke and fog.
