Seitz® IR Series Depth Filter Sheets - Pall Corporation (PLL)

Data Sheet FBIRENaSeitz ® IR SeriesDepth Filter Sheetsfor Distilled Spirits FiltrationSeitz IR series depth filter sheets were developed to meet theproduction needs and requirements of the distilled spiritsindustry.DescriptionA visually bright finished product free from visible particles isone of the main objectives of spirits filtration. Components(C12-16 fatty acid esters, terpenes, proteins or their complexcompounds with metals and/or phenols) of some spirits mayprecipitate if calcium ion levels are too high. Magnesium mayalso cause precipitations in tannin containing spirits likewhisky and brandy. Standard filter sheets contain smallquantities of these extractable ions from the raw materials.IR Series filter sheets undergo a proprietary treatment thatresults in extremely low levels of extractable ions makingthem the ideal solution for distilled spirits applications.FeaturesMedia produced by a specificmanufacturing process (lowcalcium and magnesium)Each individual filter sheet islaser etched with the sheetgrade, batch number andproduction date.Benefits• Reduced risk of precipitate indistilled spirits• High economic efficiency dueto a long service life• Full traceabilityApplicationsGradeKS 50 IRK 100 IRK 250 IRK 800 IRApplicationPolishing filtration in white spiritsChill filtration of white spiritsChill filtration of tannin containing spiritsor white spirits high in fatty acidsParticle removalSeitz IR Series Filter SheetsPacking label includes sheetgrade, batch, identificationnumber and a fork andglass symbol.• Applicability for food contactapplications clearly indicatedNominal Retention 1K 800 IRQuality• Filter sheets produced in a controlled environment• Manufactured according to ISO 9001:2008 certified• Quality Management SystemK 250 IRK 100 IRFood Contact CompliancePlease refer to the Pall website www.pall.com/foodandbev fora Declaration of Compliance to specific National Legislationand/or Regional Regulatory requirements for food contact use.KS 50 IR0 5 10 15 20Nominal retention rate [μm]1Measured under laboratory test conditions. Removal performance of filtersheets is nominal and dependent on process conditions. There is nostandardized method among manufacturers for its characterization.
