The guide passage 34 is provided such that the length of the passage is longer than that of the direction changing passage 32. That is, since the path of the direction switching path 32 is formed to be longer than the path of the guide path 34, the amount of oil particles included in the air stream passing through the direction switching path 32 is larger than that of the air passing through the guide path 34 Is collected.

The more the number of the guide for forming the flow path 30 with respect to the flow path 30 leading from the inflow part 102 to the discharge part 202 is, the more the efficiency of collecting the oil particles and the pollutant is improved. However, The pressure loss of the airflow formed by the airflow increases, and the flow noise and the vibration noise can be increased. On the contrary, as the number of the guide forming the flow path 30 is decreased, flow noise and vibration noise can be reduced, but the efficiency of collecting oil particles and contaminants is reduced.

In the embodiment of the present invention, the directional switching flow path 32 is provided so that the air flow is interrupted by the direction change or the flow is obstructed, or the direction of the flow path 30 is shorter than the direction changing flow path 32, The oil particles and contaminants pass through the guide channel 34, which is formed to be long, so that the pressure loss can be reduced and the collection efficiency can be improved.
