LOCAL CLEANED AIR SUPPLY DEVICE

摘要

A local cleaned air supply device includes: a power supply unit, a control unit, and a freely rotatable cleaned air supply unit. The cleaned air supply unit, which includes a fan driven by driving electric power, and of which a height position, a swing angle in a left-right direction, and a tilting angle can be freely adjusted, is configured so that air drawn therein is cleaned by passing through a pre-filter and a main filter and is then discharged toward a front side thereof from an air discharge opening. The cleaned air supply unit also includes a sighting unit that visualizes a range in which high cleanliness is guaranteed in a space on the front side of the cleaned air supply unit. The sighting unit includes a plurality of laser emitting units that output laser beams, to surround the range, toward a front side of the air discharge opening.
