EXACTPORETM TUBULAR FILTER

MORE SAFETY AND LOWER COSTS IN BIGCASTINGS WITH EXACTPORETM TUBULARFILTERSThe use of filter products is common practice and at
the same time a critical factor for success in foundries.
Depending on the filter technology used, not only is metal
cleanliness improved, but production costs can also be
drastically reduced by cutting down on rework and scrap.
More specifically, the demands placed on large-scalecasting processes require innovative solutions to exploit
the advantages of filtration. This is because these processes must combine the efficient use of filter material forlarge tonnages with a high degree of process reliability.
Especially in big castings, with low quantities but very
high tonnage per piece, the avoidance of filter breakage isan extremely relevant aspect. With such casting dimensions, errors caused by filters or other process steps must
be avoided at any time to prevent excess scrap and highcosts.
The tubular EXACTPORETM filter with the EXACTFILLTM
filter housing combines these advantages optimally.

Customizable EXACTPORETM filter
EXACTPORE™ filters avoid loose particles thanks to thehighest structural integrity. In addition, the new filters offer
almost all possibilities regarding pore design. The filter
materials can also vary. EXACTPORE™ filters are offeredin both standard zirconia (PSZT) and higher purity zirconia(PSZM), as well as in aluminum oxide. This enables theproduction of completely customized variations.
Tubular filter for large castings
The design of tubular and cylindrical ceramic filters has
been further improved for utilization in the largest steel andiron castings. Thanks to the sophisticated structures andgeometries, coupled with a housing system designed foreasy and safe handling, fast and effective installation ispossible. By using the available casting systems, numerous
combinations are possible, offering a solution for almost
every application.
High performance filtration with tubular EXACTPORETM
filters and EXACTFILLTM filter housingTogether, tubular EXACTPORE™ 3D filters withEXACTFILL™ filter housings provide a powerful combination for metal filtration. The high-performance system shows
its strength in terms of process costs: Due to the enormous
filtration capacity, robustness of the material, pore structure as well as the self-supporting geometry of the tubular
EXACTPORETM filters, the solution offers particularly great
advantages for the very cost-intensive areas of casting
rework and machining. Foundries can therefore achieve
considerable savings in terms of energy consumption, tool
wear and working time.
