Abstract
A cylindrical radial flow type dust collector filter for filtering the fluid flowing in the radial direction thereof is disclosed. The filter is composed of a cylindrical first filter member having a zigzag-shaped cross section in the flowing direction of the fluid, a second filter member having flowing resistance smaller than that of the first filter member, which is arranged outside of the first filter member so as to cover the outer periphery thereof and a third filter member having flowing resistance substantially the same as that of the second filter member, which is arranged inside of the first filter member so as to cover the inner periphery thereof and to define an open passage for the fluid in the axially central portion thereof.
