Abstract
A filter well suited for paint arrestor usage having a monolithic high loft manmade fiber body with a convoluted flow contact surface. The filter is preferably formed by a convoluter as in one with a roller set and blade cutter to form mirror image fiber filter sheets from a received fiber batt. Provided is a well mixed proper fiber blend, such as one having a set of fibers made of a majority of course fibers joined by way of thermal bonding fibers which facilitate, during convoluting, formation of a crisp cut and high integrity three dimensional surface, as in one of rows of peaks separated by valleys. The projection/recess arrangement over the flow contact surface as well as the thickness and relative projection-to-base dimensions are arranged to provide a high paint holding capacity without too fast a load up of, for example, paint particles and while avoiding too great of a pressure drop within that load up time.
