DOKUMENTASJON AV DINAIR LUFTFILTER Jørgen Ludvigsen Swegon AS 24. mai 2012 19. juni 2013

Dokumentasjon Vår produsent av luftfilter; DINAIR har nedenstående relevant dokumentasjon ift. gjeldende forskrifter og standarder. Eurovent Standard EN 779:2012 Både MaxFlo og GreenFlo F7 tilfredsstiller energiklasse A. Rapportering pågår inn til Eurovent, da standarden ennå ikke er fullstendig integrert. Vedlagt energiberegning utfra forskriftskrav. Dokumentasjon av filter TESTRAPPORTER Utføres av Statens Provningsanstalt (SP), VTT eller andre godkjente testlboratorier.det vanlige er å dokumentere hele og halve moduler i hver filterklasse. Dokumenteres iht. EN 779:2012 og på nyere testrapporter inngår også Energiklassing.Vedlagt testrapport på Dinairs kompaktfilter DinPleat V F8 helmodul som holder energiklasse A (målt 1471 kwh mot kravet som er 1600 kwh). I filterdokumentasjonen inngår vitale testfakta knyttet rundt areal, starttrykkfall, sluttrykkfall, støvkapasitet m.m. P-merking Posefilter i filterklasse F5, F6, F7 og F8 er P-merket iht. sertifiseringsregler for luftfilter SPCR 022. Dette er en garanti fra en nøytral tredjepartsinstans på at filterene oppfyller de krav som stilles til kvalitet og funksjon. SP, Sveriges Provnings- og Forskningsinstitut overvåker kontinuerlig konstruksjon, produksjon og testing av P-merkede filter. Kvalitet og Miljø (miljøfilter CO 2 ) Kvalitet og miljøsertifisert iht. ISO 9001 og ISO 140001. Gjennom å velge luftfilter med en klimasmart konstruksjon kan du redusere CO 2 - utslippene vesentlig. Bare ved å velge bort oljebasert plast i rammene kan en spare opptil 6 kg CO 2 pr. helmodul. Dinair har utviklet ett nytt luftfilter GreenFlo der mengden av fossilt syntetfiber av PP er minimert og blitt erstattet av fornyelsesbare PLA-fiber (fra planter), samt 30 % lettere stålramme gir lavt CO 2 utslipp ved forbrenning. Viser til fullstendig rapport Luftfilters klimatpåverkan utarbeidet av Sweco som kan bestilles separat (NOK 900,-) Emballasje Våre komprimerte filterkartonger leveres med 2 filter i hver, og inneholder tetningslist. Returposer fås på forespørsel, da ca. 70 % svarte at de ikke benyttet medsendte returposer i plast. Vi vil ikke bidra til ekstra forsøpling ved å sende med unødig emballasje. 2(2)
