MPI Series Inside-to-Out Flow Flushing Pleated Paper Filter Cartridges


The Facet Flushing Filter elements are designed to be used in place of coalescer elements in a coalescer separator vessel during flushing on new systems or when there’s been repairs to the existing equipment. The elements are less expensive than coalescer elements and have more filtration media for better solids holding capacity. Benefits, features and materials of construction are similar to our MP Series filter elements, except designed to flow inside to outside same as coalescer cartridges

These cartridges are constructed to meet the demanding requirements of the industrial filter market. Media with high efficiency throughout the life of the cartridge is available in ratings of 0.5 to 5 micron. We recommend replacing cartridges when the differential pressure reaches 15 psi. Our pleated paper filter media is made from a variety of natural and synthetic fibers. The fibers are bonded using various resins to provide excellent filtration and solids holding characteristics.

Features & Benefits
  • Less expensive than coalescer cartridges.
  • More solids holding capacity than coalescer cartridges.
