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.
