<p>A local air purification device (1) is provided with: push hoods (2, 3) having air flow opening faces (23) for discharging purified uniform air flows; and a pair of guides (4, 5) forming opening faces (41, 51) at downstream end sections of the pair of guides (4, 5), the pair of guides (4, 5) being provided on the sides of the push hoods (2, 3) which face the air flow opening faces (23) and extending from the air flow opening face (23) sides toward the downstream sides of the uniform air flows. The push hoods (2, 3) are disposed in such a manner that the respective air flow opening faces (23) face each other. The opening faces (41, 51) of the guides (4, 5) are made to face each other at an interval to form an open region between the opening faces (41, 51) of the guides (4, 5). Purified uniform air flows which are discharged from the air flow opening faces (23) hit each other within the open region and flow to the outside of the open region, and this causes the inside of the guides (4, 5) and the inside of the open region to have a higher level of cleanliness than other regions.</p> |
