DesignFilling filter: cylinder screen - flow direction from center to outside. Ventilating filter: Flow direction bi-directional (air IN / OUT). The star- shaped pleating of the filter material results in: • largefiltersurfaces • lowpressuredrop • highdirt-holdingcapacities • longservicelife

Quality management according to DIN EN ISO 9001

Toensureconstantqualityinproductionandoperation,ARGO-HYTOSfilter elements undergo strict controls and tests according to the following ISOstandards:

ISO 2941 Verification of collapse/burst pressure ratingISO 2942 Verification of fabrication integrity (Bubble Point Test)ISO 2943 Verification of material compatibility with fluids

ISO 3968 EvaluationofpressuredropversusflowcharacteristicsISO 16889 Multi-Pass-Test(evaluationoffilterfinenessand dirt-holding capacity) ISO 23181 Determination of resistance to flow fatigue using high viscosityfluid

Various quality controls during the production process guarantee the leakfreefunctionandsolidityofourfilters.
