Hollingsworth & Vose, East Walpole, MA, has signed a global licensing agreement with Minneapolis-based Donaldson Company, covering technology used to produce nanofiber filter media and nanofiber-containing filter elements for pleated air filters for on-road vehicle applications. Under terms of the license H&V will make, use and sell nanofiber filter media under certain patents and patent applications related to this market application owned by Donaldson. This arrangement will allow H&V's customers to use such filter media in connection with the manufacture, marketing and sale of filter products using Donaldson's technology. The goal of Hollingsworth & Vose and Donaldson is to provide new innovative filter performance in pleated air filters for use in on-road vehicle applications. It has been shown that nanofiber technology offers dramatically improved filter element life in such applications, particularly when challenged with diesel soot contaminants. Diesel soot contaminants have been shown to more closely represent actual conditions encountered in on-road automotive and truck filtration applications.
