Abstract

A local air cleaning apparatus () is provided with push hoods () having an air flow opening face () for blowing out a cleaned uniform air flow and a pair of guides () provided on sides of the push hoods () having the air flow opening faces (), the guides () extending from the sides thereof having the air flow opening faces () toward downstream sides of the uniform air flows to form opening faces () at downstream-side end portions of the guides. The push hoods () are arranged such that the respective air flow opening faces () are opposed to each other. The opening faces () of the guides (), are spaced apart from and opposed to each other to form an open region between the opening faces () of the respective guides (). The cleaned uniform air flows blown out from the air flow opening faces () collide with each other in the open region to flow out of the open region so as to allow the insides of the guides () and the inside of the open region to have higher cleanliness than other regions.
