STAUFF pressure filters have a wide range of clogging indicators available. If no indicator is specified, the port is sealed by
a plug (HI-O). The clogging indicators are actuated by the differential pressure (ëp) across the element. The special piston
design minimizes the effects of peak pressures in the system. An optional thermal lockout (thermo-stop) is available to prevent
false indication under cold start conditions. Fluid temperature must be at least 20øC (68øF) for the indicator to function.
