a main body having an empty space and having an intake port formed through a first side thereof to be connected with the exhaust part and a discharge port formed through a second side; and
a filter disposed at a first side in the main body,
wherein a first guide pipe through which fluid flowing into the intake port flows to a second side in the main body and a second guide pipe formed along an outer surface of the first guide pipe are disposed in the main body, and when fluid is guided into the main body by the first guide pipe, moisture in the fluid is kept in the main body and gas in the fluid moves toward the filter through a space between the first guide pipe and the second guide pipe, is filtered out, and is then discharged through the discharge port, and
wherein the space in the main body includes a first space that communicates with the intake port, a second space that is disposed at a first side of the first space to communicate with the discharge port and in which the filter is disposed, a third space that is positioned between a second side of the first space and the second space, a second guide hole is formed at the first side of the first space toward the second space, and a first guide hole is formed at the second side of the first space toward the third space;
the first guide pipe has a first side connected to the intake port and a second side extending through the first guide hole to be positioned in the third space and has a diameter smaller than the first guide hole; and
the second guide pipe has a first side connected to an inner edge of the first guide hole and a second side extending along the outer surface of the first guide pipe to be positioned in the third space.
