Thompson - Strainer Brochure

For enhanced capability, any Thompson Strainer can be outfitted with a Pressure Differential Alarm (PDA) or Automatic Timer Flush Package (ATF-EA-1.5) or both (PDA/ATF-EA-1.5). The Pressure Differential Alarm Package continuously monitors the inlet and outlet system pressure. When the pressure differential exceeds the preset limit, a switch-gauge triggers a siren and visual flashing alarm. These alarms are intended to alert maintenance personnel that the strainer screen needs to be removed from the strainer housing for manual cleaning.
