<p>This filter is used for cleaning air by removing foreign matters, such as liquid droplets, contained in the air. A separation unit (23) is formed by: a port block (13) having a primary port (11) and a secondary port (12) formed therein; and a separation cylindrical body (20) attached to the port block. A blade cylindrical body part is provided inside a swirling-flow creating chamber (24) of the separation unit (23), the blade cylindrical body part being formed by arranging, in the shape of a cylinder, a plurality of blades that extend axially along the inner peripheral surface and that are slanted in the circumferential direction. The air that has flowed axially into the swirling-flow creating chamber (24) is turned into a swirling flow by the blade cylindrical body part, and, in a separation chamber (25), foreign matters such as liquid droplets are discharged toward a recovery container. The cleaned air is guided from a discharge pipe (37) to the secondary port (12).</p> |
