A connecting apparatus of the present invention is to connect a cyclone for sampling atmospheric particle with a filter assembly. The present invention comprises: a pipe which is combined with the filter assembly and the cyclone and formed hollow inside to connect a filter of the filter assembly and an outlet of the cyclone; and a carbon steel pipe combined with the pipe. The pipe is formed to surround an outer circumference surface of the cyclone outlet, and the carbon steel pipe is formed to surround the outer circumference surface of the pipe. Hence, air leakage is doubly prevented in between the cyclone and the filter assembly. |
