To provide a moveable air curtain for a purpose of preventing droplet infection due to infectious diseases, which is arranged in a gap between persons facing each other so that, if the face-to-face condition continues, air that may be contaminated with virus does not directly scatter to both of the persons facing each other.SOLUTION: A low-speed air curtain airflow 500 and a high-speed air curtain airflow 501 have different wind speeds. Each airflow is sucked in from an airflow suction port 103, and then divided into two flows. One of which is sterilized and returned again as an air curtain airflow by virtue of blown wind of a low-speed blower 400. The other is sterilized and returned again as an air curtain airflow by virtue of blown wind of a high-speed blower 401. An air curtain is so characterized that, an air circulation close circuit is formed such that the low-speed air curtain airflow 500 is devised so as to be attracted to the high-speed air curtain airflow 501, release of the low-speed air curtain airflow 500 at downstream is reduced, and almost all air curtain airflow is sucked by the air suction port 103.SELECTED DRAWING: Figure 1 【課題】感染症による飛沫感染予防を目的とし 対面者の対面状態が継続する場合にウイルス汚染の可能性のある空気が対面者双方に直接飛散しないようその間隙に設置する移動可能なエアーカーテンを提供する。【解決の手段】低速エアーカーテン気流５００と高速エアーカーテン気流５０１として吹出す風速に違いを持たせ それぞれの気流は送風吸込口１０３から吸込まれるようにし、その後２つの流れに分割し、一方は、低速送風機４００の送風力により殺菌浄化され再度エアーカーテン気流として還流する。また他方は、高速送風機４０１の送風力により殺菌浄化され再度エアーカーテン気流として還流する。低速エアーカーテン気流５００は高速エアーカーテン気流５０１に引き寄せられるように工夫し低速エアーカーテン気流５００の下流での放散を少なくし、概ね全てのエアーカーテン気流を送風吸込口１０３にて吸い込めるようして、空気循環閉路回路を形成するエアーカーテンを特徴とする。【選択図】図１
