3. Theinflowflushestheentireworkzoneofthecabinet;withinthemainchamberofthecabinet,
negativepressure(relativetotheambientenvironment)ismaintainedinordertoensurethatno
chemicalfumesorvaporsescapetheworkzone.
4. Airistakenthroughanactivatedcarbonfiltermountedintheinterior;thisremovesallfumesfrom
theexhaustairstream;exhaustairisre‐circulateddirectlybacktotheroomfromthetopofthe

FiltraCheckisatrademarkserviceprovidedbyEsco’sfumefiltrationdivision.Customerswhointendto
purchaseaductlessfumehoodbutareunsurewhetherthecabinetissuitablefortheirapplication,can
forwardalistofchemicalsthattheywillbehandlingandtheirpatternofusagetoEsco'sFiltraCheckservice


APDFQuestionnaireformisavailableathttp://ductless.escoglobal.com/.Thisquestionnairecanbe
downloadedandeitherforwardedbyemailorbyfaxtoEsco.Aftercarefulanalysisoftheprovidedchemicals


Thisdocumentwillrecommendtheappropriatelaboratoryequipment;ductedfumehoodorductlessfume
