Provided is a local cleaned air supply device that makes visual confirmation of the range of cleaned air space possible, is able to simply adjust the direction in which cleaned air is discharged, and also makes possible easy confirmation of the suitability of the direction of airflow. The present invention has a power supply unit (3), a control unit (4), and a cleaned air supply unit (5) supported so as to be rotatable. The cleaned air supply unit (5) has a fan driven by drive electric power supplied by the power supply unit (3), a pre-filter, and a main filter mounted therein. The cleaned air supply unit is configured such that intake air is discharged toward the front from the air discharge opening (5a) after being cleaned by passing through the pre-filter and the main filter, and is also configured such that the height position, the angle of swing in the left and right direction, and the like can be adjusted freely. The present invention has a laser light emitting unit (7) (sighting means) that makes visible the range of highly cleaned air space formed forward of the clean air supply unit (5) by the cleaned air supplied from an air discharge opening (5a). |
