Description
PSS Plus Series Junior Style Metal Elements
For Low Flow Liquid and/or Environmental Applications
PSS Plus Series porous metal elements in junior style (4463) are designed for low flow liquid and/or gas applications requiring 316L stainless steel porous metal construction.
PSS Plus Series filters are Pall’s most recent development in porous metal filtration. The filters utilize a new state-of-the art manufacturing method to fabricate elements that have more uniform pore structure within the metallic media to increase filtration efficiency and tighten permeability.
The fine sintered stainless steel structure enables filtration in applications with high temperature, pressure, and solvent resistance. They are recommended for clean steam service and well suited for liquid or gas applications including solvents chemical intermediates, heat transfer fluids, polymers, pharmaceuticals, and high-temperature gases.
With a filtration area of 30 in2 (194 cm2), these filters are designed specifically for low flow liquid and/or gas applications.
