CLOGGING INDICATORS DESCRIPTION During the system operation, the pressure drop through the lter increases as the element clogs, due to the contaminant retained. The lter 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 lter. 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 lter element replacement.

ATEX Vacuum gauges Vacuum switches On return and low pressure lters the clogging indicator can be a pressure gauge or a pressure switch, measuring the pressure upstream the lter. On some return lters and on high pressure lters, the clogging indicator can be of differential type: measuring the pressure upstream and downstream the lter and activating a signal when the differential pressure reaches the set value. On suction lters the clogging indicator is a vacuum gauge or a vacuum switch, measuring the depressure downstream the lter. All the UFI lters have the port for the indicator as a standard feature; if the lter is ordered without indicator the port is plugged with a removeable plug allowing the indicator to be added easily at any time.
