Description
For Aggressive Liquid and/or Culinary Grade Steam Filtration Applications
PSS Plus series porous metal filter elements are designed for aggressive liquid and/or steam filtration applications requiring 316L stainless steel porous metal construction.
PSS Plus series metal elements are Pall’s most recent development in porous metal filtration. The elements utilize a new state-of-the art manufacturing method to fabricate elements that have a 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, culinary grade steam and solvent resistance. They are recommended for clean steam service and well suited for liquid or gas applications including solvents chemical intermediates, heat transfer and cryogenic fluids, polymers, pharmaceuticals and high-temperature gases.
| Features | Benefits |
| All stainless steel construction | Compatible for applications like steam, chemicals, high temperature gases |
| More consistent permeability | New process allows for a tighter range of permeability |
| High pressure and corrosion resistance | Withstands high reverse flows |
| New manufacturing process reduces production time lead | Flexibility in order procurement |
| ISO 9001 Certified Facility | Manufactured for use in conformance with cGMP |

Clean Pressure Drop
| Liquid Service | Gaseous Service |
| Aqueous Pressure Drop psi/gpm/ft2 | Air Pressure Drop psi/acfm/ft2 |
| 0.13 | 0.013 |
1 Pressure drop in psi obtained by multiplying value shown by actual flow desired in gpm, viscosity of liquid in centipoise (if other than 1 cp).
2 Pressure drop in psi using the 10:1 ratio of liquid:gas to be confirmed using IMR.
