<p>A filter system for compressed air comprising a first filter means and a second filter means, wherein variations of a filter performance in the first filter means is eliminated, periodical replacement of the first filter means is not necessitated, and further, costs of the first filter means are reduced advantageously. In the filter system for the compressed air, wherein liquefied fine particles and solid fine particles which are contained in the compressed air are separated from the compressed air by use of the first filter means (32), while, the liquefied fine particles and the solid fine particles which remain in the compressed air are removed or made to disappear by use of the second filter means (34), as the first filter means (32), a deflector (68) formed along the axis thereof with spiral vanes, for swirling air is used and arranged such that the axial direction thereof coincides with the air flow direction, whereby the compressed air is swirled, so that the liquefied fine particles and the solid fine particles can be separated by the centrifugal separating action.</p> |
