Polymer Filter Elements  (Click here for more polymer filtration products)

For over 30 years, Purolator Facet has been designing and manufacturing polymer filter elements to meet the growing needs of polymer producers worldwide.  Purolator Porofelt® and Pormesh® elements feature the most advanced media technology and manufacturing techniques in the industry.  These features provide the user with reliable and consistent filtration, and extend the life of the filter well beyond that of competitive filters.

 

Furnace sintering at over 1100º C in a controlled atmosphere causes metal molecules to migrate across contact points of the various layers.  Recrystallization takes place to form a completely integrated structure.


Poromesh® Media

Porofelt® Media
Features & Benefits:
  • Electron beam welds.  Electron beam welding permanently joins the filter media, end fittings and core.  The process is performed in an oxide-free vacuum chamber using 4% of the heat input of conventional welds.  The risk of media sensitization during welding is eliminated.

    •  
  • Diffusion-bonding.  Each layer of filter media is metallurgically bonded at every point of contact.  This helps ensure stable pore size and structure at high pressures, with no media migration or wire loss.  Additionally, the stress-relieved wires enhance the filters' corrosion resistance.

    •  
  • Wide range of micron ratings and media.  Porofelt® diffusion-bonded fiber metal felt depth media are available from 3µ - 60µ absolute.  Poromesh® diffusion-bonded wire mesh surface media are available from 10µ - 200µ absolute.

    •  
  • In-house core manufacturing.  The two-stage cold forming process results in maximum uniformity and strength.  In addition, electropolishing is used to remove all burrs and provide a smoother surface for polymer flow.
