Duraclear® filters are pleated polypropylene (PP) depth type filters designed to provide exceptionally high dirt holding capacity and long service life. The Duraclear® filter medium is a network of continuous, self-bonded PP microfibers manufactured with precisely controlled fiber uniformity and density. The resulting filter porosity is extremely uniform, precise and consistent in service. Duraclear® filters do not channel or unload trapped contaminants under even the most extreme process conditions. Duraclear® filters contain no resin binders to break down or leach out in service.
