Panel filters are manufactured of progressive thermally smoothened synthetic polyester having high dust holding capacity and high constancy for humidity. The filter media is framed by a rigid polyester-, cardboard-, or plastic frame, which makes filters completely incinerable. For more information on Halton’s panel filters, see the PDF product sheets below, which contain details on, among other things, their uses, materials, and technical properties. To view the product sheets, you need the Adobe Reader software, which can be downloaded from the Adobe Web site.
