Filter assembly for metallic and intermetallic tube filters

A filter assembly and a filter element system, the filter assembly for holding the filter element including a porous metallic type body having two opposing ends, one defining a weldable open end and the other defining a closed end;

• the filter element body having a uniform diameter, said filter assembly and filter element system comprising:
• (a) a filter housing, said filter housing having a certain axial length and having a peripheral sidewall, said sidewall defining an interior chamber;
• (b) a one piece, all metal, fail-safe/regenerator device, having a top and bottom end, disposed within the interior chamber of the filter housing, extending beyond the axial length of the filter housing, said device containing an outward extending radial flange near the top of the device within the filter housing, for seating an essential sealing means, the device also having heat transfer media disposed between a screening means at the top of the device within the filter housing and a screening means at the bottom of the device;
• (c) one essential sealing means consisting of one compliant gasket separate and apart from the filter housing, said compliant gasket positioned next to and above the outward extending radial flange of the fail-safe/regenerator device said gasket effective to provide a seal between the filter housing and the fail-safe/regenerator device;
• and
• (d) a porous metallic corrosion resistant superalloy type filter element body welded at the bottom of the metal fail-safe/regenerator device outside of the filter housing.
