Working Principle:


BOWNT BOS is an automatic self-cleaning filter with a screen,which can remove impurities with a size bigger than the filtration grade.

A drainage valve is equipped to the end cover of the filter. When start the filter, feed flow through the inlet to the inner screen surface, impurities continuously accumulated on the screen surface, which increasing the differential pressure between inner and outer screen. When the differential pressure meets the preset value 0.5bar(7psi), the pressure switch(PDS) send a signal to the controller to start back washing cycle, open the drainage valve and let the sewage out.
