1. Air Shower

The largest source of dust and germs in the industrial-clean room and the bio-clean room, etc. is the person entering or exiting.

Therefore, before entering the room, the particles of dust and germs attached to the surface of clothes, etc. should be removed by clean high-speed air (about 20m/s) with the filter.

As a side effect, people are restricted from entering the clean room, and the air shower itself acts as a reserve room, so that you can see the effect of blocking outdoors.
