Pleated elementsCustomer Info No. 27Filter components Introduction: Pleated elements signi cantly increase the ltration area in a given construction space. In addition, they reduce the total volume required for a de ned ltration surface. Pleated elements are made from ribbons, which are pleated and cut to size. Endless pleated elements are made having suitable joints. The individual fabric layers are simultaneously cut and welded along their longitudinal side by means of ultrasonic (US) slitting or heat cutting. Cutting to a de ned number of pleats is done using US-slitting or other suitable cutting technologies. Various lter media and lter materials can be combined, e.g. synthetics, steel, glass Up to 5 layers are possible, e.g. lter fabric with a support fabric, non-woven depth lter with woven surface lter, etc.Pleat width ranges from 20 to 1200 mmProduct details Pleat heights range from 6 mm to 50 mmDifferent pleat heights can be combinedPleat counts are unlimited Product details Endless pleated elements are formed using ultrasonic welding or metal clamping Pleated elements can be packed into PE bags that are closed by weldingEndless pleated elements can be supplied in blister packs Pleated elements made of SEFAR MEDIFAB fabrics are double-bagged The label shows all the necessary information and allows complete traceability to the polymer Customer-tailored solutionsExtensive choice of lter materialsWide range of dimensionsOptimal utilization of construction spaceLowest priming volume Biocompatible products according to USP Class VI and ISO 10993Full traceabilityBlister packaging signi cantly simpli es handling Metal clip closurePreviously, US-welding was the most common used technology to fabricate endless pleated elements. However, this technology has its limitations, especially when it must be applied to the wide variety of materials now available. To produce pleated elements for the automotive industry and other general applications, Sefar set up a specialized environment using state-of-the-art technology and machinery. This allows Sefar to produce pleated lter elements suitable for almost all customer needs and using any material.Advantages of metal clip closureMaterial independent (synthetic fabrics, wire mesh, eeces,...)Independent of thickness (multi-layer)Temperature-resistant (limit --� fabric resistance)Extremely durable and resistantNo bulging (supporting effect)Multi-layer pleats possibleNo frayingSolid connection regardless of material surface and coating.Application areasOil- ltrationFuel ltrationAir- ltrationDust- ltrationWet ltrationMedical ltration 3105-0161-000-00 | 11.2010 | SEFAR is a registered trademarks of the SEFAR AGwww.sefar.com ltration@sefar.comBuffalo, Depew, NY – USA ltration@sefar.usKansas City, MO – USAkc ltration@sefar.usinfo.bdh@sefar.comSefar S.A. de C.V.Iztapalapa, D.F. – Mexicoinfo.mexico@sefar.comSefar TenylTenyl Tecidos Técnicos Ltda.contato.brasil@sefar.comSefar Singapore Pte.
