New Technologies in Liquid Filtration are Focus of Technical Presentations at 2012 AFS Conference

Attendees at the 2012 AFS Annual Conference will learn about the application of new and complex composite technologies used in liquid filtration during two technical presentations by Hollingsworth & Vose (H&V), a global leader in the supply of technically advanced nonwovens for engine, high efficiency, and liquid filtration.

“Introduction to NANOWEB® Materials and Application in Liquid Filtration” will be presented at the conference’s Latest & Best I session on June 6th at 2:34 p.m. The session will include study findings on the filtration properties of a polypropylene-based NANOWEB Advanced Nanofiber Technology. The study researched NANOWEB media performance including fractional efficiency, water flux, and dirt holding capacity versus some standard phase-inversion polymeric membranes.

Recently introduced by Hollingsworth & Vose, the NANOWEB technology platform features a new type of microporous fibrous membrane. The membrane structure is predominantly composed of randomly packed polymeric nanofibers that create a highly voided and interconnected network. The chemical and mechanical robustness of the nano-nonwoven material is dependent on the choice of polymers, basis weight and some proprietary processing methods.

The presenter, Jack Manns, is Director of Marketing Specialty and Liquid Filtration Products, HESF Division, H&V. Manns has more than 30 years of experience in the filtration and nonwovens industry, including 24 years at H&V in various marketing positions related to both air and liquid filtration applications.
“Complex Composites in Liquid Filtration” will be presented at the conference’s Latest & Best II session on June 6th at 4:41 p.m. Complex composite media, developed by combining and optimizing different processes and materials into a single media, are changing the engine and industrial fluid filtration market segment.

At H&V, in one example, two main processes — wetlaid structures and microporous fibrous membranes — are being combined in new ways. Nano fibers in a variety of materials, ranging from 60 to 700 nanometers, are combined with larger wetlaid bases consisting of glass, synthetic and/or cellulosic fibers. The resulting composite is a new, single media with capabilities for diverse liquid fluid applications well beyond either non-woven by itself.
The presenter, Andrew Shepard, is the Global Director of Marketing, Engine and Industrial Division, H&V. Shepard has more than 20 years of experience in the automotive and powertrain industry, working on new product development, engineering, design, management consulting and product management.

Admission to both presentations is free to attendees of the 2012 AFS Annual Conference. No reservations are needed.
