<p>A filter apparatus that while maintaining a high revolution speed, realizes reduction of filter element vibration. The filter apparatus is one comprising cylindrical main-body vessel (1); tubular filter element (7) having a multiplicity of filter pores (7a) for removal of foreign matter contained in liquid, disposed in the main-body vessel (1) coaxially with the main-body vessel (1); inflow pipe (5) for introduction of a liquid containing separation objects, disposed in a direction tangential to a circumferential wall surface of the main-body vessel (1); outflow pipe (8) for outflow of the filtrate having passed through the filter element (7); and foreign matter discharge pipe (12) for discharging of the separation objects together with the liquid, disposed in a direction tangential to the circumferential wall surface of the main-body vessel (1), wherein the filter pores (7a) partially or wholly are formed into a taper such that the pore size on a fluid inflow side is different from that on a fluid outflow side.</p> |
