Clogging Indicators for Pressure Filter

CLOGGING INDICATORS FOR PRESSURE FILTERS

 During the system operation, the pressure drop through the filter increases as the element clogs, due to the contaminant retained. The filter element must be replaced when clogged and anyway before the pressure drop reaches the bypass valve set value. For this reason it is recommended a clogging indicator on the filter. It gives a visual or electrical indication and must have a set value lower than the bypass valve set value, to get an exact indication of the right time for filter element replacement.
