GTH Screen Filter

The GTH filter consist of two stages of filtration; a course pre-filter and a stainless steel fine screen. The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake which filters out even finer particles, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the control system. The solids are removed from the fine screen using a focused backwashing method aggressively sucking the dirt off the screen, similar to a vacuum cleaner, and are carried to the drain via the rinse valve. The dirt collector rotates and moves linearly, ensuring the entire screen is completely cleaned for each cycle. Both Electrically Driven and Hydraulically Operated (no power required) configurations can be used. The entire cleaning process takes only seconds without any interruption of flow to the main system.
