<p><P>PROBLEM TO BE SOLVED: To provide an outside air cleaning apparatus in which the main exhauster is installed downstream of the air cleaning means and which controls the inflow of non-purified air into downstream of the air cleaning means. <P>SOLUTION: The outside air cleaning apparatus 1 is provided with an air incorporation part 21 and an air ejection part 22. The apparatus also has an inner housing 2 to store the air cleaning means 5 for purifying the air introduced from the air incorporation part 21 and the main exhauster 9 to exhaust the purified air to the air ejection part 22, which is located between the air cleaning means 5 and the air ejection part 22, an outer housing 3 to surround the inner housing 2, which is provided with an outside air introduction port 31 and an air outlet 32, in which an air introduction passage to connect the outside air introduction port 31 with the air incorporation part 21 is formed in the housing interspace 11 between the outer face of the inner housing 2 and the inner face of the outer housing and in which the air outlet 32 communicates with the air ejection part 22 without passing through the housing interspace 11, and a negative pressure formation means 42a to maintain the housing interspace 11 under negative pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
