Low maintenance, easy to operate, continuous cleaning with KSF Series self-cleaning filters. Flow capability up to 35 m3/h. These self-cleaning filters come with a top mounted electric motor which continuously rotates a scraper on the surface of an internal wedge wire element to remove dirt. This eliminates the need for backwashing and makes these filters easy to use and maintain. An advantage of using wedge wire elements is that the V shaped profile avoids blockage by particulates. A manual drain valve can be used to remove the dirt from the vessel at regular intervals. Alternatively, an optional pneumatically operated valve with timer can be used to remove dirt automatically at timed intervals.
