air shower introduction

air shower introduction:
 Air shower can be divided into two types:one is for the works,one is for the goods.  
 The air shower is a chamber that blows high pressured air on an individual before worker or goods enters a controlled area. The air is forced at high speed through SS air shower nozzles that are aimed at the individual so that contaminants are knocked off. The air is then cycled through prefilters and then through a high efficiency particulate HEPA filter or an Mini-pleat Ultra low penetration air filter(ULPA Filter).
 The effectiveness of an air shower depends on many factors, including the size of the shower, the type of contaminants being removed, and how the individual behaves within the shower. In order for the air shower to work efficiently, an individual must usually stand in the center of the chamber with his hands above his head and turn 360° while the air is blowing. The nozzles should also be positioned so that the air can clean the person effectively. In addition, the duration of the shower should be long enough to remove the contaminant. After the process is finished, the individual should also wait a certain amount of time before going into the controlled area in order to allow the air shower to remove any contaminant that settle.
