Applied 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.

Porosity
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.

Materials
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.

Properties
Sintered porous metal media, in its simple form (such as a sheet or tube), has very definable performance characteristics. These characteristics include flow in gas or liquid applications, filtration efficiency, surface characteristics, 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 products.
