Provided is a filtering device for filtering foreign substances from fluid. The filtering device comprises: a device housing for discharging processed fluid which has a filtering means where fluid is passed through and filtered; and rotary current type foreign substance removing means which sprays the fluid while forming a rotary current towards the filtering means and which is comprised to remove foreign substances from the filtering means. Foreign substances are filtered by being contained in fluid especially including supplied water and cooling water used broadly in factories, and foreign substances attached on the filtering means (screen structure) are filtered via the fluid rotary current which is forcibly formed via multidirectional spray control. Hence, the entire filtering performance is maximized, the maintenance becomes easy, and the lifetime is extended. |
