Filter for Booster Installation Prototypehttp://www.shelco.com/pdfs/MH_final.pdfPleated polypropylene media cartridge0.5 micron, 90% efficiency ratingOver 5-1/2 square feet of media, very high dirt holding capacity than other cartridges.$24 eachPressure drop vs GPM at 0.5 micronAt 2 GPM, delta P at less than 1 PSIDRecommended Changeout 25 PSID

Filter MonitoringTap on Filter housing for inlet and outlet pressure monitoringLocal pressure gaugesRemote Pressure Transducers, 0.5% of full scale accuracy4-20 mA output signalRemote monitoring from Main Control RoomAcknowledgement to Kent Triplett, Sensor testing and verificationLoop Power Source, 10-30 VDC

Alarm Set PointFilter Delta P Clean, at 1 GPM, 0.3 PSIDCorrector needs 80 PSID for 0.6 GPMBooster 95 LCW System provides S=120 PSID min

Bottom LineInstalling Small Filter in Enclosure will teach us :Impact on New Corrector ProgramHealth of the Booster 95 LCW SystemProtect prototype corrector during critical testing
