Abstract
A local air cleaning apparatus () is provided with a push hood () having an air flow opening face () for blowing out a cleaned uniform air flow and a guide () provided on a side of the push hood () having the air flow opening face (), the guide () extending from the side thereof having the air flow opening face () toward a downstream side of the uniform air flow to form an opening face () at a downstream end portion thereof. The push hood () is arranged such that the uniform air flow blown out from the air flow opening face () passes through the inside of the guide () and then collides with an air collision face (W) on a downstream side of the opening face (). The opening face () of the guide () is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face () and the air collision face (W). The cleaned uniform air flow blown out from the air flow opening face () collides with the air collision face (W) and flows out of the opening region, thereby allowing the inside of the guide () and the inside of the open region to have higher cleanliness than other regions.
