Porous Technologies, Inc. media is manufactured from special
grades of atomized metal
powders. To achieve the wide range of porosities
available in our media, each powder lot is prescreened to a specific
size range and distribution specification. Prepared powders are
precompressed in special tooling to form the basic shapes for
the finished media.
The "green" media is sintered in carefully controlled atmospheric
furnaces to create strong, monolithic structures that can be
used as is or incorporated into engineered assemblies.
Typical porosity grades, as measured in a standardized bubble point test, include
0.2, 0.5, 1, 2, 5, 10, 20, 40, 60, and 100 micron. Applied Porous
Technologies, Inc. can also custom-tailor media to provide the
exact filtration or flow characteristics needed for any application.
The standard material used in our media is 316L Stainless Steel. For special
applications, media can also be manufactured from a variety
of other materials including nickel, Inconel®, Hasteloy®,
titanium, and others. This allows the end user to choose the material that
best fits their application to provide the necessary strength,
heat resistance, corrosion
resistance, and process compatibility.
Sintered porous metal media, in its simple form (such as a sheet
or tube), has very definable performance characteristics. These
flow in gas or liquid applications, filtration efficiency, surface
strength, and corrosion resistance. Tailoring these properties to
meet the requirements of a specific application makes the media
a true engineering medium from which the design engineer can
develop a broad range of end
