PROBLEM TO BE SOLVED: To solve the problems in which, as a conventional air shower is constituted so that at least air jet is not jetted from a door for entrance, there is a surface which is not hit by the air jet unless a person who enters an air shower or an object which enters the air shower rotates, and in which flying objects such as insects and the like enter the air shower while a door on the dirty side is opened.SOLUTION: In addition to a body unit including a plurality of air jet nozzles and a fan motor, an air shower includes a plurality of air jet nozzles and a fan motor on a door on the dirty side and a door on the clean side. When the body units are arranged on the opposing surfaces, the fan motor which the dirty side door includes and the fan motor which the clean side door includes are controlled separately and they can be operated individually as well. When the body units are arranged on the adjacent surfaces, the fan motors which the body units include respectively are controlled separately and they can be operated individually as well.SELECTED DRAWING: Figure 1 |
