Viledon Filter Mats:Clean Air by the RollProductOverview

Viledon:The brand, its philosophy, its productsReg. No. 1420Expert certificationis not onlyreassuring, . it minimizes yourrisks as well!Where all Viledon filter mats excel!Freudenberg, the world’s largest manufacturerof nonwovens, and an acknowledged specialistin questions of air filtration, uses only highperformance nonwovens produced inhouse forViledon filter mats, made of synthetic-organicfibers like polyester or polyolefine.Besides the technical filtration data like arrestance, pressure drop, and dust holding capacity, there are additional criteria which characterize a filter mat’s overall performance:Viledon filter mats, for example, are moistureresistant up to 100 % relative humidity, and thermally stable up to 100 C. For use in dryer systems, the PA filter mats can even withstand 120 Cfor short periods.Viledon filter media satisfy the stringent requirements of Fire Class F1 to DIN 53 438 andare self-extinguishing.The "inner" values of our filter mediaIn order to achieve maximized arrestance performance combined with ultra-favorable pressuredrop characteristics, Viledon filter mats are progressive in structure, with layers of differing fiberdiameters being arranged behind each other soas to ensure that the density of the fiber layers increases towards the clean-air side. This optimizesthe defined filter performance and the dust hold-ing capacity, resulting in long useful lifetime forthe filter concerned.Quality is paramountAt Freudenberg, quality is an across-the-boardcommitment, which starts off with full comprehension of the customer's requirements, beforetranslating these into products, processes andservices.A modern quality management system to ISO9001 monitors all operations, from the very beginning of development work and applicationengineering consultancy all the way through todelivery of the finished product.The consistent quality of Viledon filter matshas been tested by an independent institute inaccordance with EN 779, and documented byimprinting the filter mats with brand name, typedesignation and filter class.The independently type-tested Viledon filtermats additionally bear the DIN mark of conformity, plus the model validation number involved.

Viledon works. Depend on it.When we recommend a particular solution foryour application, our advice is backed up bydecades of experience and in-depth know-howconcerning dusts, testing methodology, standards and specifications, and a whole lot more.Experience and know-how geared to makingsure that both staff and machinery are effectivelyprotected against air pollutants.Dependability is paramount and essential fortrouble free operation of filter systems or filterunits. With Viledon filter mats, dependabilitymeans a filter optimally tailored to the requirements involved, so as to provide the desiredarrestance performance over the filter’s entire lifetime.Dependability starts with the fibers used.Only non-breakable fibers are used for Viledonfilter mats, thus preserving the original nonwovenstructure throughout the entire period of operation.Applications with high air flow rates demandhigh mechanical strength in the filter material. Foryour own particular operation, we recommendthe filter mat which will offer you maximizeddimensional stability for ultra-reliable operation.Cost efficiency that's worth affordingDependability and cost efficiency – two aspectswhich are inextricably linked. After all, a filterwhich is not dependable in its performance,which cannot cope properly with the operatingconditions involved, will inevitably increase yourmaintenance and filter replacement costs. A filterwhich has been incorrectly dimensioned anddesigned for the clean-air quality required, or forthe intake air conditions encountered, may consume too much energy, or fail to reach its specified useful lifetime.One of the key factors in the cost efficiency ofViledon filter mats is the progressive structure ofthe filter media involved. This is complemented byselection of the right filter mat for each application, optimally matched to the filtration requirements encountered. We will be pleased to helpchoose the right filter system for your own individual needs, and will prepare a solution gearedto optimum filtration at maximized cost efficiency.The environment will thank youWith Viledon air filters, you are making your owncontribution towards a cleaner environment. Sothe least we can do is try to make our products asenvironmentally compatible as possible. Whenwe make Viledon filter mats, we pay particularattention to the following points, with concomitantadvantages for you:We do not use any additional bonding agentsin our filter mat production process. This meanshomogeneous filter material which is easier todispose of.Only high quality synthetic-organic fibers(e.g. polyester and polyolefine) are used inViledon filter mats.The environment-friendly P15 filter mats canbe cleaned by washing, beating or spraying,and can then be used again. Your advantage:this avoids waste and cuts your filtering costs.The filter media are not dyed, but are innatural white, i.e. no unnecessary chemicals areused.Viledon filter mats made of purely syntheticorganic fibers can be disposed of without anyproblems, e.g. in refuse incineration plants.All Viledon filter mats, both rolls and cutpieces, are supplied in recyclable transport packaging.Our goal:an ideal synthesis ofcost efficiency . technicalpeak performances . and responsibleenvironmentalawareness!
