Working principle

BOWNT BOS is a self-cleaning filter with filter element, a screen, which can removes the particles with a size bigger than the filtration grade. An electromagnetic drainage valve equipped to the end cover of the filter. When water flows from the filter inlet through the filter screen to the outlet, impurity particles continuously accumulated on the inner surface of the filter screen, increasing pressure differential between inner and outer screen surface. When differential pressure reaches a predetermined value (0.05MPa), pressure switch transfer signal to control unit to open the drainage valve to let the sewage, out.
