RF Industries’ mini pleat filters use polypropylene media with a three-dimensional, progressive structure. This innovative design incorporates nanofibers that effectively capture even the smallest particles. Unlike competitive products that only have nanofibers on the surface, our media distributes them throughout its entire thickness. As a result, the fibers are resistant to damage and do not shed. This unique construction allows us to use the media in both surface-loading and depth-loading applications.
