20090199717 | Filtration Medias, Fine Fibers Under 100 Nanometers, and Methods - An electrospinning fine fiber production methodology for generating a significant amount of fibers with diameters of less than 100 nanometers is provided. Also, a filter media composite comprising a substrate layer and an electrospun fine fiber layer having a increased efficiency relative to pressure drop and/or a controlled pore size distribution is provided. According to some embodiments nylon is electrospun from a solvent combination of formic and acetic acids. | 08-13-2009 |
20100181249 | Filter Having Melt-Blown and Electrospun Fibers - A multi-layer filter media including at least one layer of melt-blown fiber filter media and at least one layer of electrospun nanofiber filter media is provided. The multi-layer filter media of the present invention is configured such that the at least one layer of the melt-blown fiber filter media is on the upstream and the at least one electrospun nanofiber filter media is positioned downstream of the at lest one melt-blown fiber filter media. | 07-22-2010 |
20110210059 | NON-PLEATED TUBULAR DEPTH FILTER HAVING FINE FIBER FILTRATION MEDIA - A non-pleated depth filter element in the form of a tubular ring of depth filter media is provided. Multiple wraps of sheets, some including fine fibers, are employed. The depth filter element has particular applications to liquid filtration applications. | 09-01-2011 |
20110210060 | EXPANDED COMPOSITE FILTER MEDIA INCLUDING NANOFIBER MATRIX AND METHOD - A composite filter media includes an expanded substrate media carrying fine fibers, wherein the fine fibers are extended with the expanding substrate media, thereby improving dust holding capacity and slowing down pressure drop increase. | 09-01-2011 |
20110210061 | COMPRESSED NANOFIBER COMPOSITE MEDIA - A coalescing media includes a compressed composite filter media comprising substrate layers and hydrophilic fine fiber layers for separating free water emulsified in fuels. | 09-01-2011 |
20110210081 | FINE FIBER LIQUID PARTICULATE FILTER MEDIA - A filter media for liquid particulate filtration applications is provided. The filter media includes a substrate and fine fibers, which are compressed together. | 09-01-2011 |
20110223330 | Fine Fiber Electro-Spinning Equipment, Filter Media Systems and Methods - Electrostatic fine fiber generation equipment such as for forming nano-fibers from polymer solution is provided. The fine fiber generation equipment includes a strand that may take the form of a stainless steel beaded chain. The beaded chain can be an endless chain entrained upon two guide wheels and driven about an endless path perpendicularly relative to the collection media. | 09-15-2011 |
