Schroeder 9Vz3 Hydraulic Filter Cartridge For Rlt, Z-Media,, And 1.5" Id. Product Details The special class of micro-glass and other fibers used in Z media are manufactured with utmost precision, to specific thicknesses and densities, and bonded with select resins to create material with extra fine passages. No other filter media can provide the benefits of Schroeder?s Excellement Z media: maximum dirt-holding capacity, superior particle capture, excellent beta stability, minimum pressure drop, high flow rate and low operating cost. The typical multiple layer construction has evolved from comprehensive laboratory testing to provide extended element life and system protection. Each successive layer performs a distinct and necessary function. The outermost layer is designed to maintain element integrity. Beyond this layer is a spun bonded scrim, offering coarse filtration and protection for the filtering layers within. Multiple sheets of fine filtering media follow, providing intricate passageways for the entrapment of dirt particles. Together, the various layers of filter media provide the ideal combination for peak filtration performance. Epoxy-coated steel wire fabric provides maximum support and rigidity. Spun bonded scrim protects intricate filtration media within. Two layers of Z media provide maximum efficiency and dirt-holding capacity with minimal pressure drop. Spun bonded scrim provides downstream media support and increased stability. Epoxy-coated steel wire fabric provides maximum support and rigidity.
