Pre-Coat Pressure Filters

Standard filter are not able to provide very fine filtration of 1 micron or lesser is required. In such cases precoat filter is used. Precoating is a process of adding a graded powder to form a layer on the standard filter media. The layer provides a larger surface area which in turn increases the dirt holding capacity. It also generates a toroidal path for the fluid, thereby entrapping the finer particles.
